[R] "function" as variable name - probably better error message

[Rainer M Krug]

Hi

The following code works as expected:


list(plot="Not any more!")

,----
| > plot <- "Not any more!")
| [1] "Not any more!"
`----

But for this I get an error:

,----
| > function <- "Not any more!"
| Error: unexpected assignment in "function <-"
`----

The error message is quite cryptic and does not help much further. Would
it be possible to provide a more useful error message in this case that
(presumably) "function" is a reserved word?

Along the same lines - is there a list of reserved words which can not
be used in R as variable names (not even as elements in a a list())?

This is not a huge problem, but it cost me a few minutes of figuring
out.

Thanks,

Rainer
