[R] Quoting underscores in variable names

[Edward C. Lang]

(please Cc: me in replies, as I am not on the r-help list)

Hi,

I have discovered that underscores are not allowed in variable names,
although this is not by any means the first instance of such a
discovery. Short of going through all my other data, and removing
underscores, is it possible to quote underscores in R? I had something like:

> plot(g\_code ~ sp\_code, data=genes)
Error: syntax error

in mind, but obviously that does not work.

Any thoughts/ideas appreciated.

Regards,

Edward.
