recodeLookup | R Documentation |
Recodes the values of a variable. Function resembles the recode

lookup |
a data.frame with exact two columns. First column contains old values, second column new values. Values which do not occur in the old column remain unchanged. |
a vector of the same length as var
with recoded values
num_var <- sample(1:10, size = 10, replace = TRUE)
lookup <- data.frame(old = c(2, 4, 6), new = c(200,400,600))
num_var2<- recodeLookup(num_var, lookup)
