Download Foundry Files locally.
Description
Download Foundry Files locally.
Usage
datasets.download_files(alias, files)
Arguments
alias |
The alias representing the Dataset. |
files |
The file paths or file properties. |
Value
A list mapping Foundry Dataset files to the local file paths where files were downloaded.
Examples
## Not run:
# Download a single file in a Dataset
downloaded_file <- datasets.download_files("my_alias", c("dir/my_file.csv"))
read.csv(downloaded_file$`dir/my_file.csv`)
# Extract text from all PDF files in a Dataset
pdf_files <- datasets.list_files("my_alias", regex = ".*\\.pdf")
downloaded_files <- datasets.download_files("my_alias", pdf_files)
contents <- lapply(downloaded_files, pdftools::pdf_text)
## End(Not run)
Lists the files stored in a Foundry Dataset.
Description
Lists the files stored in a Foundry Dataset.
Usage
datasets.list_files(alias, regex = ".*")
Arguments
alias |
The alias representing the Dataset. |
regex |
A regex used to filter files by path. |
Value
The lists of file properties.
Examples
## Not run:
# List all PDF files in a Dataset
all_files <- datasets.list_files("my_dataset", regex=".*\\.pdf")
# Get all file names
file_names <- sapply(all_files, function(x) x$path)
## End(Not run)
Reads a tabular Foundry dataset as data.frame or an Apache Arrow Table.
Description
Reads a tabular Foundry dataset as data.frame or an Apache Arrow Table.
Usage
datasets.read_table(
alias,
columns = NULL,
row_limit = NULL,
format = "data.frame"
)
Arguments
alias |
The alias representing the Dataset. The Dataset must be tabular, i.e. have a schema. |
columns |
The subset of columns to retrieve. |
row_limit |
The maximum number of rows to retrieve. |
format |
The output format, can be 'arrow' or 'data.frame'. |
Value
A data.table or an Arrow Table
Column types
Note that types may not match exactly the Foundry column types. See https://arrow.apache.org/docs/r/articles/arrow.html for details on type conversions from an arrow Table to a data.frame.
Examples
## Not run:
# Download a subset of a tabular Dataset
df <- datasets.read_table("my_input", columns = c("columnA", "columnB"), row_limit = 1000)
## End(Not run)
Upload a local file or folder to a Foundry Dataset.
Description
Upload a local file or folder to a Foundry Dataset.
Usage
datasets.upload_files(files, alias)
Arguments
files |
The local files and folders to upload. If a folder is provided, all files found recursively in subfolders will be uploaded. |
alias |
The alias representing the Dataset. |
Value
A list mapping local file paths to the corresponding Foundry Dataset file.
Examples
## Not run:
# Upload RDS files to a Dataset
local_dir <- file.path(tempdir(), "to_upload")
dir.create(local_dir)
saveRDS(iris, file.path(local_dir, "iris.rds"))
saveRDS(Titanic, file.path(local_dir, "Titanic.rds"))
datasets.upload_files(local_dir, "my_output")
## End(Not run)
Writes a data.frame to a Foundry dataset.
Description
Writes a data.frame to a Foundry dataset.
Usage
datasets.write_table(data, alias)
Arguments
data |
A data.frame or an arrow Table. |
alias |
The alias representing the Dataset. |
Column types
Note that types may not be exactly preserved and all types are not supported. See https://arrow.apache.org/docs/r/articles/arrow.html for details on type conversions from a data.frame to an arrow Table. Use arrow::Table$create to use more granular types.
Row Names
Row names are silently removed.
Examples
## Not run:
datasets.write_table(mtcars, "my_output")
## End(Not run)
Loads a config from an environment variable with format 'FOUNDRY_CONFIG_KEY' or from an option with format 'foundry.config.key'.
Description
Loads a config from an environment variable with format 'FOUNDRY_CONFIG_KEY' or from an option with format 'foundry.config.key'.
Usage
get_config(name, default = NULL)
