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

Question

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 1

toLatex of the utils package does the job:

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

Output:

# \begin{tabular}{lD{.}{.}{7}D{.}{.}{7}D{.}{.}{7}D{.}{.}{7}}
# \toprule
 # & \multicolumn{1}{c}{edf} & \multicolumn{1}{c}{Ref.df} & \multicolumn{1}{c}{F} & \multicolumn{1}{c}{p-value} \\
# \midrule
# s(lcavol) & 1.0000000 & 1.0000000 & 48.8654347 & 0.0000000 \\
# s(lweight) & 7.4334733 & 8.3759397 & 2.9521585 & 0.0054553 \\
# s(age) & 1.7609527 & 2.1888342 & 3.2466098 & 0.0402275 \\
# s(lbph) & 1.7480193 & 2.1293872 & 2.3329425 & 0.0998080 \\
# s(lcp) & 3.3087460 & 4.0189658 & 1.3792509 & 0.2484695 \\
# s(pgg45) & 1.1277962 & 1.2388741 & 0.2681440 & 0.6563885 \\
# \bottomrule
# \end{tabular}

Answer 2

I was having the same problem converting the output of GAM models (mgcv package), I got what I wanted with the "itsadug" package authored by R. Harald Baayen.

Convert model summary into Latex / HTML table for knitr / R Markdown reports.

data(simdat)

Model with random effect and interactions:

m1 <- bam(Y ~ Group+te(Time, Trial, by=Group),data=simdat)
summary(m1)
gamtabs(m1, caption='Summary of m1')

See for more examples:

vignette("inspect", package="itsadug")
