Dear list, I have to use a list of lists containing vectors.
For instance : [[1]] [[1]][[1]] [1] 1 2 3 [[1]][[2]] [1] 3 2 1 I want to attribute vectors to the main list without use of an intermediate list, but it does not work : x <- list() x[[1]][[1]] <- c(1, 2, 3) x[[1]][[2]] <- c(3, 2, 1) Thanks in advance, Carlos ______________________________________________ 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.
