Dear sirs, I have a data that is generated like this:
> dat1 <- data.frame(V1 = rep(1, 5), V2 = sample(c(40:45), 5)) > dat2 <- data.frame(V1 = sample(c(0,1), 5, replace = TRUE), V2 = > sample(c(40:45), 5, replace = TRUE)) What I want to do is to obtain a data frame that contain list of list. > hiv $hiv.dat1 $hiv.dat1$V1[[1]] [1] 1 1 1 1 1 $hiv.dat1$V2[[1]] [1] 41 42 43 40 44 $hiv.dat2 $hiv.dat2$V1[[1]] [1] 0 1 1 0 0 $hiv.dat2$V2[[1]] [1] 42 43 40 44 43 But why this line of command failed to create that? > hiv <- list(hiv.dat1 = as.list(dat1), hiv.dat2 = as.list(dat2)) Especially it gives "$hiv.dat1$V1" instead of "$hiv.dat1$V1[[1]]". How can we correct that? I need this particular data structure required for a specific package (ROCR). - G.V. ______________________________________________ R-help@r-project.org mailing list 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.
