Replace: Replace elements of a vector

In tdeenes/eegR: Analyze EEG Signals

Description

Replace replaces the values in x which are equal to from to the values given in to. The values in to are recycled to match the length of from.

Usage

Replace(x, from, to, digits = 10L)

Arguments

x	a raw, integer, character or numeric (double) vector, or a factor
from	vector of elements to replace
to	the elements
digits	integer indicating the number of decimal places to be used in the comparison of double values (ignored if is.double(x) is FALSE)

Value

a vector with replaced values

Examples

x <- c(NA, c("a", "a", "z", "e", "q"))

# note that 'from' might contain values which are not present in 'x'
xr <- Replace(x, from = c("w", "a", "e"), to = c("ww", "aa", "ee"))

# only 'a' and 'e' were replaced
xr
stopifnot(identical(length(x), length(xr)))
stopifnot(identical(xr[c(2, 3, 5)], c("aa", "aa", "ee")))

# the missing value is not affected
stopifnot(is.na(xr[1]))
