...x <- list( 1, list(3,NULL,4), 5 ) > x [[1]] [1] 1 [[2]] [[2]][[1]] [1] 3 [[2]][[2]] NULL [[2]][[3]] [1] 4 [[3]] [1] 5 This is a good thing for me as it can be passed through into C++ where I can know the value is missing. (Can't seem to detect a NA from C++ for some reason. There is RF_isNull in the API but no RF_isNA that I can find!) Is it possible to put a null in an already created list. e.g. now do > x[[2]][[2]] <- NULL > x [[1]] [1] 1 [[2]] [[2]][[1]] [1] 3 [[2]][[2]] [1] 4 [[3]] [1] 5 But x[[2]][[2]] has been deleted. Many thanks Regards, David
