I am using gsub to remove numbers for each element of a list. Code

below.
testList <- list("this contains a number 1000","this does not

removeNumbers <- function(X)

gsub("\\d","",X)
}
outputList <- lapply(testList,removeNumbers)
However, when I try to find the number of words in outputList as
follows
outLength <- lapply(strsplit(outputList," "),length)
By changing a single letter "l" -> "s" you could get that to succeed:
> outputList <- sapply(testList,removeNumbers)

[[1]]
[1] 4
[[2]]
[1] 4
it throws out the following error:
Error in strsplit(outputList, " ") : non-character argument
