R help - Aug 2011 - xtable - caption missing with float=FALSE

Hi,

For some reason I'm finding that my table caption is disappearing if I 
print xtable output with the floating argument set to FALSE. Below is a 
very simple Sweave file that produces two tables the first has no 
caption and the second has a caption (if you want to see it 
http://www.zevross.com/temp/test.pdf).

Does anyone know what I can do to fix this?

% begin Rnw file

\documentclass[a4paper]{article}

\begin{document}

<<results=tex, echo=FALSE>>library(xtable)

atable<-data.frame(a=1:10, b=rnorm(10))
print(xtable(atable, caption="FLOAT"), floating=FALSE)
print(xtable(atable, caption="NO FLOAT"), floating=TRUE)
@

\end{document}


Sweave("test.Rnw")
texi2dvi("test.tex", pdf=TRUE, clean=TRUE)

Hi,

If you compare the output of the two commands, the 'floating = TRUE'
variant places the tabular environment within a table environment. The tabular
environment does not support the \caption command, table does, hence no caption
if the tabular is not contained within a float (floating = FALSE).

HTH,
