Interestingly, cat() does the pasting job in the simplest
possible way:

> temp <- c("November", "December","Monday","Tuesday")
> cat(temp,sep=",")
November,December,Monday,Tuesday> 

[copied from the R console; note the trialing ">" which is
 the command prompt for the next input -- not part of the
 output of cat() ]

with output to screen (or to nominated file). But there
seems to be no way to persuade cat to *return* this result
as a value, which could be assigned to a variable.

If there were such a way, that would be a very smooth solution!
