Replace values across a data frame

Replace all occurrences of given values in all columns of a data frame. Factor levels are preserved (and extended by the replacement values), and numeric/logical columns are only touched where a value actually matches, so unrelated entries keep their exact binary representation.

Usage

replace_values(data, to_replace, replace_with)

Arguments

data

The input data frame to be modified.

to_replace

A vector of values to be replaced within the data frame. This must be the same length as replace_with.

replace_with

A vector of corresponding replacement values. This must be the same length as to_replace.

Value

Modified data frame with specified values replaced.

Examples

# \donttest{
data <- data.frame(
  q1 = c("neg2", "neg1", "0"),
  q2 = c("1", "neg2", "neg1")
)

replace_values(
  data,
  to_replace = c("neg2", "neg1"),
  replace_with = c("-2", "-1")
)
#>   q1 q2
#> 1 -2  1
#> 2 -1 -2
#> 3  0 -1
# }
