Dear List, The following code produces a list, which is what I what:
set.seed(123) tmpf <- function() { x <- rpois(rpois(1,4),2) } n <- 3 m <- replicate(n,tmpf()) m [[1]] [1] 3 2 4 [[2]] [1] 0 2 4 2 2 5 2 [[3]] [1] 2 0 4 1 0 Now I need something that would to extract iteratively (or as many times as the size of 'n') the values that are greater than 2 in each component of 'm' into another list such that the sub-list would be: [[1]] [1] 3 4 [[2]] [1] 4 5 [[3]] [1] 4 Below is what I tried: for(i in 1:3) sub.list <- lapply(m,subset,m[[i]]>2) > sub.list which gives me something different from what I want: [[1]] [1] 4 [[2]] [1] 4 [[3]] [1] 4 Any help would be appreciated. > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 2.1 year 2005 month 12 day 20 svn rev 36812 language R ______________________________________________ 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 and provide commented, minimal, self-contained, reproducible code.
