fun_by_row tidyverse_syntax for funs on rows: row functions inside dplyr mutate

Description

Must be used inside the dplyr function mutate in order to work.

Usage

row_sum(..., ignore_na = FALSE, rationalize = FALSE)
row_sum_(..., ignore_na = TRUE, rationalize = TRUE)
row_mean(..., ignore_na = FALSE, rationalize = FALSE)
row_sum_(..., ignore_na = TRUE, rationalize = TRUE)
row_sum(..., ignore_na = FALSE, rationalize = FALSE)
row_mean_(..., ignore_na = TRUE, rationalize = TRUE)
row_mean(..., ignore_na = FALSE, rationalize = FALSE)

Arguments

vars or tidyselect function

ignore_na

a logical indicating whether missing values should be removed

rationalize
