Hi guys, here is a simple thing I want to do but it doesn't work:
I have a vector of the element indexes that I want to delete called index
so when I write myList[[index]] <- NULL to delete these elements here is
what I get:
Error in myList[[index]] <- NULL :
more elements supplied than there are to replace
Isn't it possible to delete multiple elements?
If your index is a list of numerical indices as opposed to names, then
just do
myList <- myList[-index]
the same way you'd delete elements from any vector.
If index is a vector of names, you need to convert it to numbers, using
something like
indexnums <- which( names(myList) %in% index )
and then use myList[-indexnums].
