R help - Jun 2009 - xtable with longtable is doublespaced, rather than single as intended

Hello,

Quick R/LaTeX question.

I have the following code within a .Rnw file:

<<label=regionalSummary,results=tex,echo=false>>cVec <-
c("RATE","SVC.PCT","AGR.PCT","IND.PCT","density00")
x.big <- xtable(aggregate(qp3[,cVec], list(qp3[,"COURT"]), mean))
colnames(x.big)[1] <- "COURT"
print(x.big, tabular.environment="longtable", include.rownames=TRUE)
@

However, in the PDF the table comes out double spaces, rather than
single spaced like in the xtableGallery document. Is there any way to
force single space behavior. I have nothing strange in my .Rnw file.

Thanks,
-stephen

Found the answer. It seems to work to wrap longtables with this set of commands:

\renewcommand{\arraystretch}{0.6}
% make a longtable
%...
\renewcommand{\arraystretch}{1.0}

Hope this is useful to someone else.
