Is there a way to tell whether an object name 1. is valid 2. is not going to cause a collision with an existing object by the same name?
For 1, you could put your names in a character vector x, then check whether x and make.names(x) are identical; if so, x contains syntactically valid names. (Do remember that almost anything can be a name if you put it in back quotes.)
For 2, you could check exists(x) to find if objects with those names exist.
