Dear group, I have the following data frame
v1 v2 v3 v4 v5 1 1 3 1 3.5 1 2 1 4 3 3.5 1 3 1 8 3 3.5 1 4 2 9 8 2.5 1 5 2 10 9 2.5 1 6 2 6 3 1.5 1 7 3 4 3 2.0 1 8 3 5 3 1.0 1 9 3 8 3 1.0 1 10 4 9 8 2.0 1 11 4 6 5 1.0 1 12 4 8 4 1.0 1 13 5 4 3 2.0 1 14 5 5 3 2.0 1 15 5 6 5 2.0 1 I'm trying to split it into data frames where each equal v1 so all v1==1 in data frame and all v1==2 in separate data frame and so on. so it would be v1 v2 v3 v4 v5 1 1 3 1 3.5 1 2 1 4 3 3.5 1 3 1 8 3 3.5 1 then v1 v2 v3 v4 v5 4 2 9 8 2.5 1 5 2 10 9 2.5 1 6 2 6 3 1.5 1 ....... ... and so on I tried a<- split(df, df$v1==1) but the resulting class is a list and when I try to access for example a$v2 it gave me NULL ?? how can I split it an get each vector of v2 for each group, lots of thanks Ragia ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
