gather_se: Distribute columns into blocks of rows.

In seplyr: Improved Standard Evaluation Interfaces for Common Data Manipulation Tasks

Description

A standard (value-oriented) interface for gather. Take values from the columns named in the columns argument and move them into blocks of rows, placing values in the new column specified by value and indicating which column each value came from in the new column specified by key.

Usage

gather_se(
  data,
  ...,
  key = "key",
  value = "value",
  columns = NULL,
  na.rm = FALSE,
  convert = FALSE,
  factor_key = FALSE,
  use_one_of = TRUE
)

Arguments

data	data.frame to take values from.
...	not used, force later arguments to bind by name.
key	character, name for new column to record which columns values were taken from.
value	character, name for new column to record values.
columns	character, names of columns to take values from.
na.rm	passed to gather.
convert	passed to gather.
factor_key	passed to gather.
use_one_of	logical, if TRUE use dplyr::one_of() instead of rlang:::'!!!'.

Value
