Sys.Date is a function. It's perfectly possible
to write string <- format(Sys.Date, "%s") (or, generically,
string <- format(sin, "%s"), etc), but it will just put some
description of the function in the string.
Also, the assignment in R is "<-", not "=".
Try:
foot <- function(){
str1 <- format(Sys.Date(),"%Y%m%d")
sprintf("99%-4s%s","nm",str1)
}
