Replace specified values with new values, in a factor or character vector.
If x is a factor, the named levels of the factor will be
replaced with the new values.
revalue(x, replace = NULL, warn_missing = TRUE)
x |
factor or character vector to modify |
replace |
named character vector, with new values as values, and old values as names. |
warn_missing |
print a message if any of the old values are
not actually present in |
This function works only on character vectors and factors, but the
related mapvalues function works on vectors of any type and factors,
and instead of a named vector specifying the original and replacement values,
it takes two separate vectors
mapvalues to replace values with vectors of any type
x <- c("a", "b", "c")
revalue(x, c(a = "A", c = "C"))
revalue(x, c("a" = "A", "c" = "C"))
y <- factor(c("a", "b", "c", "a"))
revalue(y, c(a = "A", c = "C"))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
