R help - Dec 2009 - Passing arguments to gpar

Dear R-users,

I would like to know how to pass arguments to gpar() without hard-coding 
them. I tried to store my arguments in a list and passed this list to 
gpar(), but it did find the way to do it properly. Any help would be 
appreciated.

a<- list(fontisze=8,col=3)
gpar(fontsize=8,col=3)
gpar(a)
gpar(unlist(a))

Hi

Are you looking for this ... ?

do.call("gpar", a)

Hi,

Yes, that is exactly it. Charlie Sharpsteen gave me the same solution 
last week but he probably just replied to me, so his email did not go to 
the list. Thanks for the reply, I appreciate it.... I always forget 
about this do.call function.
