[R] Equivalent of Nothing (in VBA) or [] in Matlab in R

[Rui Barradas]

Hello,

There are other types of "empty" objects in R (zero length or dimension).
Maybe some of these

x <- list()
length(x)

x <- matrix(list())
dim(x) <- c(0, 0)
x

Matlab's [] is the empty matrix so maybe the second works.
Other possibilities could be x <- numeric(0) (or integer(0) or
character(0)).
Trial and error might get you there...

Hope this helps,

Rui Barradas
