[R] Slight fault in error messages

[Yan Wong]

Just a quick point which may be easy to correct. Whilst typing the  
wrong thing into R 2.2.1, I noticed the following error messages,  
which seem to have some stray quotation marks and commas in the list  
of available families. Perhaps they have been corrected in the latest  
version (sorry, I don't want to upgrade yet, but it should be easy to  
check)?

 > glm(1 ~ 2, family=quasibinomial(link=foo))
Error in quasibinomial(link = foo) : ‘foo’ link not available for  
quasibinomial family, available links are "logit", ", ""probit" and  
"cloglog"

 > glm(1 ~ 2, family=binomial(link=foo))
Error in binomial(link = foo) : link "foo" not available for binomial  
family, available links are "logit", ""probit", "cloglog", "cauchit"  
and "log"

I hope this is helpful,

Yan
