Quite a handy couple of lines of code to subset a list in R to just those elements which meet a certain condition. Here’s an example to return only those elements of a list which are a certain class.
Thanks to this StackOverflow answer.
list.condition <- sapply(input.list, function(x) class(x)=="desired.class")
output.list <- input.list[list.condition]
