Thanks for your post, I was aware of strsplit, but really could not find out how i could use it.

I tried like in your example ...

A<-c(1,2,3) B<-c("dgabcrt","fgrtabc","sabcuuu") C<-strsplit(B,"abc")

[[1]]

[1] "dg" "rt"

[[2]]

[1] "fgrt"

[[3]]

[1] "s" "uuu"

Which looks promissing, but here C is a list with three elements. But how to create the two vectors I need from here, that is

("dg","fgrt", "s") and ("rt","","uuu")

(or how to get access to the substrings "rt" or "uuu").

Greetings

Manuel

Dear R users,

I have a dataframe with one character field, and I would like to create two new fields (columns) in my dataset, by spliting the existing character field into two using an existing substring. ... something that in SAS I could solve e.g. combining substr(which I am aware exist in R) and "index" for determining the position of the pattern within the string. e.g. if my dataframe is ... A B 1 dgabcrt 2 fgrtabc 3 sabcuuu Then by splitting by substring "abc" I would get ... A B B1 B2 1 dgabcrt dg rt 2 fgrtabc fgrt 3 sabcuuu s uuu Do you know how to do this basic string(dataframe) manipulation in R Saludos, Manuel ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
