for example, suppose able define function returned name of assignment variable concatenated first argument: a <- add_str("b") # "ab" the function in example above this: add_str <- function(x) { arg0 <- as.list(match.call())[[1]] return(paste0(arg0, x)) } but arg0 line of function replaced line name of variable being assigned ("a") rather name of function. i've tried messing around match.call , sys.call, can't work. idea here assignment operator being called on variable , function result, should parent call of function call.
