Re: [R] extracting columns from a list
I forgot to answer to the last part of your question. I think what you call a list is actually an element of a list, right? If so, the command you want depends on the way you want to combine these elements. For example, the following lines will extract columns 12 and 13 of any array-like element of your list and bind them into columns of a same array (if all your elements have the same number of rows). List2 - lapply (NameOfYourList, function (dat, NumCol) dat[,NumCol], c(12,13)) Array2 - do.call (cbind, List2) If you meant something else by 'combine, please be more explicit.

Re: [R] extracting columns from a list
Le ven. 23 mai à 09:37, mohamed nur anisah a écrit : Dear all, i have 2 lists of data with each of the list contain 14 columns. No, you have one list with two elements; each is a 14-column data frame. How am i going to extract column 12 and 13 from each of the list ?? Let's call your list 'x'. Then lapply(x, [, c(12, 13)) or, better yet, lapply(x, [, c(breakp.start, breakp.end)) if I counted your columns correctly. and can i combine my extracted columns to form a single list. You mean a single data frame? Given that the number of rows is not the same in both elements, no. If they were, using sapply() instead of lapply() would do the trick.
