Arguments

x	A vector.
to_replace	Either a vector of values to replace, or a list of vectors for the sets of values to replace.
replace_with	A vector of values, either a single value or a vector matching in length with to_replace.

Value

A vector.

Examples

# Example vector
x <- rep( LETTERS[1:4], each = 3 )
# Replace all cases
replace_cases( x, c( 'A', 'B', 'C', 'D' ), 1:4 )
# Replace some cases and use default value for others
replace_cases( x, c( 'A', 'B', 'C' ), 1:3 )
# Replace combinations of cases
replace_cases( x, list( c( 'A', 'B' ), c( 'C', 'D' ) ), 1:2 )

# Robust to NA values
x <- c( 1, 1, 2, 2, NA, NA )
replace_cases( x, c( 1, 2, NA ), c( 'A', 'B', '' ) )
