Stargazer and gam - how to include the whole summary output?

When fitting a generalized additive model with smoothed splines stargazer only returns the main effects and not the smooth terms which you can see in

summary(pros.gam)
. Can stargazer return these as well? Or is there another function or package that can do the job?

library(ElemStatLearn)
library(mgcv)
library(stargazer)

pros.gam=gam(lpsa~s(lcavol)+s(lweight)+s(age)+s(lbph)+svi
+s(lcp)+gleason+s(pgg45),data=prostate)

summary(pros.gam) # Table should include the smooth terms that are visible here
stargazer(pros.gam,summary=TRUE)

Answer

toLatex of the utils package does the job:

require(utils)
toLatex(summary(pros.gam)$s.table) 

Output:
