[R] How to clean up missing values in a list of lists

ists$content[which(nchar(pull_lists$content)==NULL)]<-NA } clean_lists <- lapply(pull_lists, clean_files) But that simply replaces *every* value with NA (similarly if I change ==NULL to <1, or <2). How can I make this code work? Best, Aron --  Aron Lindberg Doctoral Candid

[R] Subsetting a list of lists using lapply

nds "manually" it returns NULL for every list, and when I run the whole apply function it says:  Error in FUN(X[[1L]], ...) : subscript out of bounds I've tried reading the sections on lists and subsetting in Hadley's Advanced R, but I still cannot figure it out.

Re: [R] Subsetting a list of lists using lapply

sometimes input[[i]]$content simply returns list(). Chuck’s solution however bypasses this and works on the full dataset (which was 8mb, which is why I didn’t upload it as a gist). Best, Aron --  Aron Lindberg Doctoral Candidate, Information Systems Weatherhead School of
