two questions about character manipulation
Hello,
Try the following.
1)
pattern <- "response."
m <- regexpr(pattern, ex) #gregexpr to get all "response"
regmatches(ex, m)
2)
gsub("\\$", "\\.", ex)
Hope this helps,
Rui Barradas

Dear all, I want to manipulate a character string such as ex<-"cbind(data$response1,data$response2)" in R in two ways: 1) extracting the "response1" portion of ex 2) replacing "$" with "." I am wondering that is it possible efficiently doing these in R?
