Hi,
try this:
paste(code,gsub("\\d+","",name)[match(code,gsub("\\D+","",name))],sep=" ")
#[1] "101001 Alta" "1032 Media" "102 Bassa" "101001 Alta" "102 Bassa"
#[6] "1032 Media"
A.K.

Subject: [R] match and substitute two variables
Hello,
I have two variables (of different length and from two different data
frames):
code<- c("101001", "1032", "102", "101001", "102", "1032");
name<- c("101001 Alta", "102 Bassa", "1032 Media");
and I would like to substitute the first variable with the second variable
according to their shared numerical part, thus obtaining the following
result:
code.new
"101001 Alta" "1032 Media" "102 Bassa""101001 Alta" "102 Bassa" "1032
Media"
I tried using: <- sapply(code, gsub, pattern="\\d+", replacement=name) but
the replacement cannot be of length more than one, thus my output is only
"101001 Alta" "101001 Alta"... I am not sure how to get the right answer...
Thank you!
