HI Team,
Need help with the below syntax.
merge.salaries[, name:=paste("nameFirst","nameLast")]. Here
merge.salaries
is the data set I have merged.
There are 2 columns nameFirst and nameLast I need to merge these two into
one and name as name however I can getting an error:
Error in `[.data.frame`(merge.salaries, , `:=`(name,
paste("nameFirst", :
could not find function ":="
Please advice.
Thanks, Shivi

Hi Shivi,
I usually do
merge.salaries$name <- paste(merge.salaries$nameFirst,
merge.salaries$nameLast)
also if merge.salaries[,
name:=paste("nameFirst","nameLast")] would work,
you would end up with a column full of "nameFirst nameLast".
Best,
Ulrik

The problem in the original post is, as clearly stated , the ":=", which is some other language, not R. From which I infer that the OP needs to spend some additional time with an R tutorial or two to learn R.
