Hey,
Try the following code:
a=c(1,2,3,4,5)
b=c(10,20,30,40,50)
c=c(100,200,300,400,500)
d=c(1000,8210,9000,8310, 7000)
e=c(,,9190,,)
to.replace=c(8210,8310,9190)
df = data.frame(a,b,c,d,e)
xdf <- apply(df, 2, function(x) x %in% to.replace)
df[xdf] <- "others"

Hi Yosub,
if "dat" is your data frame, try something like (untested):
dat$code[!dat$code %in% c("8210", "8310", "9190")] <- "others"
the general idea being create a logical vector of codes that match the
three you want, use "!" to negate this (so you are getting all codes
NOT in the ones you wan
Hello,
I have a data frame with 2 columns: year and code. In code column, I want to
replace elements that are not "8210", "8310", or "9190" with "others".
