separate_rows: Separate a collapsed column into multiple rows.

Description

If a variable contains observations with multiple delimited values, this separates the values and places each one in its own row.

Usage

separate_rows(data, ..., sep = "[^[:alnum:].]+", convert = FALSE)

Arguments

data

A data frame.

...

Specification of columns to separate. Use bare variable names. Select all variables between x and z with x:z, exclude y with -y. For more options, see the select documentation.

sep

Separator delimiting collapsed values.

convert

If TRUE, will run type.convert with as.is = TRUE on new columns. This is useful if the component columns are integer, numeric or logical.

Examples

df <- data.frame(
  x = 1:3,
  y = c("a", "d,e,f", "g,h"),
  z = c("1", "2,3,4", "5,6"),
  stringsAsFactors = FALSE
)
separate_rows(df, y, z, convert = TRUE)
