Is there an R equivalent of the pythonic "if __name__ == "__main__": main()"?
python, r
Solution
I think that the `interactive()` function might work.
This function returns `TRUE` when R is being used interactively and `FALSE` otherwise. So just use `if (interactive())`
i.e. the equivalent is
if (!interactive()) {
main()
}
Problem
The objective is to have two simple ways to source some code, say func.R, containing a function. Calling `R CMD BATCH func.R` initializes the function and evaluates is. Within a session, issuing `source("func.R")` simply initializes the function. Any idea?
