observation_count: Get the number of times a row appears in a dataframe

In meerapatelmd/rubix: rubix Package

Description

Not to be confused with a total row count of a dataframe (ie 'nrow()'), this is a shortcut for 'group_by_all()' followed by 'count()'.

Usage

observation_count(data, desc = TRUE)

Arguments

data	A dataframe or tibble.
desc	If TRUE, the output is arranged in descending order. Otherwise it is arranged in ascending order.

Value

Ungrouped dataframe with all input columns with the addition of an 'n' column for the count.

Examples

library(tidyverse)
test_data <- 
        tibble(
                Group = sample(c("Apple", "Pear"), size = 10, replace = TRUE),
                A     = sample(c(NA_integer_, 1:3), size = 10, replace = TRUE),
                B     = sample(c(NA_integer_, 4:6), size = 10, replace = TRUE),
                C     = sample(c(NA_real_, seq(from = 6.01, to = 6.09, by = 0.01)), size = 10, replace = TRUE)
        )
