plot.incidence() now reverts to the previous behaviour of plotting ticks on either side of the interval as opposed to centering within the interval.plot.incidence() introduced with new release of ggplot2 (bug report) As a temporary fix, dates are now centered within the interval instead of to the left of the interval.seq.Date() can handle (e.g. “5 weeks”) can be handled by incidence() (see https://github.com/reconhub/incidence/issues/67)$weeks is now added to the incidence object, which contains an “aweek” classmake_breaks() will automatically calculate breaks from an incidence object for plotting.scale_x_incidence() will produce a ggplot2 “ScaleContinuous” object to add to a ggplot.plot.incidence() argument labels_iso is deprecated in favor of labels_week$isoweeks if the weeks are ISO 8601 standard, but users should rely intead on $weeks instead. The $isoweeks element will be removed in a future version of incidence.as.incidence() argument isoweeks has been deprecated in favour of standardincidence() will no longer allow a non-standard first_date to override standard = TRUE. The first call toincidence()specifyingfirst_datewithoutstandardwill issue a warning. To use non-standard first dates, specifystandard = FALSE. To remove the warning, useoptions(incidence.warn.first_date = FALSE)`. See https://github.com/reconhub/incidence/issues/87 for details.citation("incidence") will now give the proper citation for our article in F1000 research and the global DOI for archived code. See https://github.com/reconhub/incidence/pulls/106incidence() now returns an error when supplied a character vector that is not formatted as (yyyy-mm-dd). (See https://github.com/reconhub/incidence/issues/88)fit() now returns correct coefficients when dates is POSIXt by converting to Date. (See https://github.com/reconhub/incidence/issues/91)plot.incidence() now plots in UTC by default for POSIXt incidence objects. this prevents a bug where different time zones would cause a shift in the bars (See https://github.com/reconhub/incidence/issues/99).first_date and last_date parameters.plot.incidence() will now respect single groups. (See https://github.com/reconhub/incidence/issues/84)as.data.frame.incidence() will now respect single groups. (See https://github.com/reconhub/incidence/issues/84)demo("incidence-demo" package = "incidence") has been updated to show use of custom colors.print.incidence() will now print isoweeks even if the $interval element is “week”.subset.incidence() will now give a more informative error message when the user specifies a group that does not exist.demo('incidence-demo', package = 'incidence') now shows plotting with show_cases = TRUE.incidence.max.days optionplot.incidence(), incidence(), and as.data.frame.incidence() For details, see https://github.com/reconhub/incidence/issues/79group_names() allows the user to retrieve and set the group names.get_timespan() returns the $timespan element.get_n() returns the $n element.dim(), nrow(), and ncol() are now available for incidence objects, returning the dimensions of the number of bins and the number of groups.plot() called show_cases has been added to draw borders around individual cases for EPIET-style curves. See https://github.com/reconhub/incidence/pull/72 for details.estimate_peak() no longer fails with integer datesincidence() no longer fails when providing both group information and a first_date or last_date parameter that is inside the bounds of the observed dates. Thanks to @mfaber for reporting this bug. See https://github.com/reconhub/incidence/issues/70 for details.internal_checks.R file has been split into the relative components.$lm field of the incidence_fit class is now named $model to clearly indicate that this can contain any model.incidence() will now accept text-based intervals that are valid date intervals: day, week, month, quarter, and year.
incidence() now verifies that all user-supplied arguments are accurate and spelled correctly.
fit_optim_split() now gains a separate_split argument that will determine the optimal split separately for groups.
A new class, incidence_fit_list, has been implemented to store and summarise incidence_fit objects within a nested list. This is the class returned by in the $fit element of fit_optim_split().
bootstrap() will bootstrap epicurves stored as incidence objects.
find_peak() identifies the peak date of an incidence objects.
estimate_peak() uses bootstrap to estimate the peak time of a partially observed outbreak.
get_interval() will return the numeric interval or several intervals in the case of intervals that can’t be represented in a fixed number of days (e.g. months).
get_dates() returns the dates or counts of days on the right, center, or left of the interval.
get_counts() returns the matrix of case counts for each date.
get_fit() returns a list of incidence_fit objects from an incidence_fit_list object.
get_info() returns information stored in the $info element of an incidence_fit/incidence_fit_list object.
incidence_fit_class instructs the user on how incidence_fit and incidence_fit_list objects are created and accessed.incidence() function, the iso_week parameter is deprecated in favor of standard for a more general way of indicating that the interval should start at the beginning of a valid date timeframe.The $timespan item in the incidence object from Dates was not type-stable and would change if subsetted. A re-working of the incidence constructor fixed this issue.
Misspelled or unrecgonized parameters passed to incidence() will now cause an error instead of being silently ignored.
Plotting for POSIXct data has been fixed.
incidence object to avoid conflicts with additional geoms such as geom_ribbon, now used in projections::add_projections.ggplot2the argument n_breaks has been added to plot.incidence, to specify the ideal number of breaks for the date legends; will work with ggplot2 > 2.2.1
added the internal function make_iso_weeks_breaks to generate dates and labels for date x-axis legends using ISO weeks
added a function add_incidence_fit, which can be used for adding fits to epicurves in a piping-friendly way
added a function cumulate, which computes cumulative incidence and returns an incidence object
new generic as.incidence, to create incidence objects from already computed incidences. Methods for: matrix, data.frame, numeric vectors
better processing of input dates, including: automatic conversion from characters, issuing errors for factors, and silently converting numeric vectors which are essentially integers (issuing a warning otherwise)
new vignette on conversions to and from incidence objects
new tests
fixed issues caused by variables which changed names in some datasets of the outbreaks package, used in the documentation
disabled by default the isoweeks in incidence; this part of the code will break with changes made in the devel version of ggplot2, which is now required by plotly
it is now possible to subset an incidence object based on Date dates using numeric values, which are interpreted as number of intervals since the first date (origin = 1)
NAs are no longer removed from the input dates, as it would cause mismatches with grouping factors.
ebola.sim -> ebola_sim and ebola.sim.clean -> ebola_sim_cleanadd an argument iso_week to incidence.Date() and incidence.POSIXt() to support ISO week-based incidence when computing weekly incidence.
add an argument labels_iso_week to plot.incidence() to label x axis tick marks with ISO weeks when plotting ISO week-based weekly incidence.
The README.Rmd / README.md now contains information about various websites for incidence as well as guidelines for posting questions on the RECON forum.
incidence now has a dedicated website https://www.repidemicsconsortium.org/incidence/ generated with pkgdown
First release of the incidence package on CRAN!
