Add data to existing data frame.

Description

Using key identifying columns, add additional columns to an existing data frame. This function allows you to match new columns based on specified IDs and you can choose what columns to add. Additionally you can specify the column number at which to add the new columns, so they are not added to the end of the data frame. Helpful for adding environmental or taxonomic data to your quadrat data.

Usage

add_data(data, add, cols, data_id, add_id, number = FALSE)

Arguments

data

A data frame you want to add columns to.

add

A data frame with columns you want to add to data.

cols

The column names from add that you wish to add to data.

data_id

The ID column in data that will be used to match rows in add.

add_id

The ID column in add that will be used to match rows in data.

number

The column number to start at to add the new columns, so they are not added to the end of the data frame. If not specified they will be added to the end of the data frame by default.

Value

A data frame with added columns.

Examples

Sites <- as.factor(c("One", "One", "One", "Two", "Two", "Three"))
Transect <- as.factor(c("1-Deep", "1-Shallow", "2-Shallow", "1-Shallow", "1-Deep", "1"))
coral_name <- c("Acropora.sp", "Leptastrea.sp", "Sinularia.sp", "Psammocora.sp", "
    Psammocora.sp", "Leptastrea.sp")
prop_cover <- c(0.1, 0.6, 0.4, 0.9, 0.2, 0.5)
coral_cover <- data.frame(Sites, Transect, coral_name, prop_cover)

corals <- c("Acropora.sp", "Leptastrea.sp", "Psammocora.sp")
lifehistory <- c("compeditive", "weedy",  "stresstolerant")
functionalgroup <- c("hardcoral", "hardcoral", "hardcoral")
coral_info <- data.frame(corals, lifehistory, functionalgroup)

add_data(data = coral_cover, add = coral_info, cols = c("lifehistory", "functionalgroup"),
         data_id = "coral_name", add_id = "corals", number = 4)

Categorize data based on contents of a column

Description

Using a column within the data frame, categorize rows in a binary of yes or no, or customize with a set of category names. Data can be categorized based on the inclusion or lack of inclusion of parts of characters, or based on exact characters. Especially useful for turning ID tags into useful categories for analysis such as morphology, bleaching, taxonomy etc.

Usage

categorize(data, column, values, name, binary = TRUE, exact = TRUE, categories)

Arguments

data

The data frame.

column

The column name which contains the data on which to categorize rows.

values

The characters or parts of characters to use to classify rows.

name

The name of the now column of categories.

binary

If binary = TRUE, the name column will be returned with "Yes" denoting that characters ,or parts of characters specified by values are present in the row, while "No" denotes that there are no characters or parts of characters specified in values present in the row. If binary = FALSE there must be categories provided which will be used to classify the presence of characters or parts of characters specified in values.

exact

If exact = TRUE only exact matches will be selected. If exact = FALSE matches will be selected if they contain the characters in the values vector and will not be limited by exact matches.

categories

The factor names denoting the presence of the characters or parts of characters specified by values. These must be specified in the same order as the corresponding element in values.

Value

A data frame with new categorization column.

Examples

Sites <- as.factor(c("One", "One", "One", "Two", "Two", "Three"))

Arguments

data

A data frame with each row representing a sampling unit (ex. a quadrat or photo).

spp

The column names containing all observations to be used in the proportion calculation. It is important to note that the proportions will be scaled to the total observations in these columns for each quadrat.

prop

If prop = TRUE, the resulting cover will be proportions. If prop = FALSE, the resulting cover will be in percentages.

total

If total = TRUE, a column containing the total number of observations at each sampling unit will be returned in a new column called total_pts. This will not be returned if total = FALSE.

Value

  values,
  select,
  keep = TRUE,
  drop_levels = TRUE,
  exact = TRUE,
  colname
)

Arguments

data

Sample Quadrat Data (0.6m by 0.9m)

Description

A data_frame that can be used with the Simple Cleaning Quadrat Data and the Cleaning and Cropping Quadrat Data vignettes to show how quadrat data can be cleaned to produce easy to analyze data frames. Data was collected by the Baum Lab and Kiritimati Field Teams. Data is the uncleaned version of data found in Maucieri and Baum 2021. Biological Conservation. doi:10.1016/j.biocon.2021.109328 The data are from photo quadrats (0.9m by 0.6m) which were randomly annotated with 54 random points each. At each of these annotated points, the substrate was identified. Photo quadrats were collected on Kiritimati Island in the Republic of Kiribati and document coral cover over time and space. The annotations and output of the data_frame were produced using CoralNet and all annotations were done manually, by trained researchers.

Sample Annotation Data for Cropping Vignette

Description

A data_frame that can be used with the Why to Crop Quadrats by Area vignette to show how quadrat data can be cropped while maintaining spatial relationships between observations. Data was collected by the Baum Lab and Kiritimati Field Teams. Data is the uncleaned version of data found in Maucieri and Baum 2021. Biological Conservation. doi:10.1016/j.biocon.2021.109328 The data are from photo quadrats (1m by 1m) which were randomly annotated with 100 random points each. At each of these annotated points, the substrate was identified. Photo quadrats were collected on Kiritimati Island in the Republic of Kiribati and document coral cover over time and space. The annotations and output of the data_frame were produced using CoralNet and all annotations were done manually, by trained researchers.

Usage

softcoral_annotations

Format

A data_frame with 4 columns, which are:

Name: Unique identification code for each quadrat.
Row: The pixel row where the annotation occurred in the photo of the quadrat.
Column: The pixel column where the annotation occurred in the photo of the quadrat.
Label: The identification for the substrate below the annotation location.

Sum columns based on matching names

Description

Select columns and attach a vector of their new names, then columns with matching names will have each row summed. This is helpful to simplify your data quickly, like simplifying at a higher taxonomic group.

Usage

sum_cols(data, from, to)

Arguments

data

A data frame.

from

The column names in data.

to

A vector of new names, with matching names being the columns where each row will be summed.

Value

A data frame with summed columns.

Examples

Sites <- as.factor(c("One", "One", "One", "Two", "Two", "Three"))
Transect <- as.factor(c("1-Deep", "1-Shallow", "2-Shallow", "1-Shallow", "1-Deep", "1-Deep"))
Acropora.tabulate <- c(0.1, 0.6, 0.4, 0.9, 0.2, 0)
Acropora.corymbose <- c(0.4, 0, 0.1, 0, 0.3, 0.5)
Gardineroseris.sp <- c(0.4, 0.9, 0.5, 0.23, 0.5, 0.6)
Psammocora.sp <- c(0.9, 0.6, 0.5, 0.8, 0.1, 0.4)
Leptastrea.sp <- c(0.5, 0.7, 0.4, 0.8, 0.2, 0.3)
coral_cover <- data.frame(Sites, Transect, Acropora.tabulate, Acropora.corymbose,
                          Gardineroseris.sp, Psammocora.sp, Leptastrea.sp)

new_names <- c("Acropora.spp", "Acropora.spp", "Gardineroseris.sp",
               "Psammocora.sp", "Leptastrea.sp")

sum_cols(data = coral_cover, from = colnames(coral_cover[,3:7]),
         to = new_names)

Extract usable observations

Description

Sum columns containing unusable observations and remove rows that contain more than the specified cutoff number of unusable points. Helpful if there are annotations that were unidentifiable and you want to remove them from the total usable observations, and you can remove quadrats with too many unusable observations.

Usage

usable_obs(
  data,
  unusable,
  max = FALSE,
  cutoff,
  above_cutoff = FALSE,
  rm_unusable = TRUE
)

Arguments

data

A data frame with each row representing a sampling unit (ex. a quadrat or photo).

unusable

A vector of column names containing unusable observations.

max

If max = FALSE, no threshold will be examined. If max = TRUE, a threshold cutoff needs to be provided where rows containing more than the cutoff will be removed from the data frame.

cutoff

The threshold number where rows containing more unusable observations than the cutoff will be removed from the data frame.

above_cutoff

If above_cutoff = TRUE, the data frame returned will be the rows containing more unusable observations than the cutoff. If above_cutoff = FALSE the data frame returned will be the rows containing equal to or less unusable observations than the cutoff.

rm_unusable

If rm_unusable = TRUE, the columns named in the unusable vector will be removed from the data frame. These columns will not be removed if rm_unusable = FALSE, though duplicate data will remain.

Value

A data frame containing summed unusable points.

Examples

#create data set for example
Sites <- as.factor(c("One", "One", "Two", "Two", "Three", "Three"))
Transect <- as.factor(c("1-Shallow", "2-Shallow", "1-Shallow", "2-Shallow",
    "1-Shallow", "2-Shallow"))
Acropora.sp <- c(1, 2, 3, 4, 5, 6)
Gardineroseris.sp <- c(6, 1, 2, 3, 4, 5)
Psammocora.sp <- c(5, 6, 1, 2, 3, 4)

Unk <- c(2, 3, 4, 5, 6, 1)
coral_cover <- data.frame(Sites, Transect, Acropora.sp, Gardineroseris.sp,
                          Psammocora.sp, Leptastrea.sp, Blurry, Unk)


usable_obs(coral_cover, c("Blurry", "Unk"))

usable_obs(coral_cover, c("Blurry", "Unk"), above_cutoff = TRUE)

usable_obs(coral_cover, c("Blurry", "Unk"), rm_unusable = FALSE)

usable_obs(coral_cover, c("Blurry", "Unk"), max = TRUE, cutoff = 8)

usable_obs(coral_cover, c("Blurry", "Unk"), max = TRUE, cutoff = 8, above_cutoff = TRUE)
