The server function of the categorycountplot module

Lets the user tally rows of a data frame by a categorical column, optionally split by a second, rendered via interactive_barchart (the same tally that interactive_count_barplot exposes as a standalone function). Identifier-like columns (e.g. a gene or sample ID/name, where almost every row has its own distinct value) are excluded, since there would be little to count beyond '1' per row.

Usage

categorycountplot(id, getAnnotation, filename = "categorycounts")

Arguments

id

Module namespace

getAnnotation

Reactive supplying a data frame (one row per feature or sample) whose categorical (non-numeric) columns are offered for counting

filename

Filename stem for the exported counts table/plot image

Examples

categorycountplot("categorycount", getAnnotation = reactive(mtcars))
#> Error in categorycountplot("categorycount", getAnnotation = reactive(mtcars)): could not find function "categorycountplot"
