Dear all I would like to export a matrix to a LaTeX "longtable" environment that would have its caption on top of the table. However xtable() seems to bar me from doing this:> print(xtable(mtcars[1:10,c(1,2)], caption="CARS"),+ tabular.environment="longtable", caption.placement="top" + , floating=F) % latex table generated in R 2.9.1 by xtable 1.5-5 package % Tue Aug 25 13:48:01 2009 \begin{longtable}{rrr} \hline & mpg & cyl \\ \hline Mazda RX4 & 21.00 & 6.00 \\ Mazda RX4 Wag & 21.00 & 6.00 \\ Datsun 710 & 22.80 & 4.00 \\ Hornet 4 Drive & 21.40 & 6.00 \\ Hornet Sportabout & 18.70 & 8.00 \\ Valiant & 18.10 & 6.00 \\ Duster 360 & 14.30 & 8.00 \\ Merc 240D & 24.40 & 4.00 \\ Merc 230 & 22.80 & 4.00 \\ Merc 280 & 19.20 & 6.00 \\ \hline \hline \caption{CARS} \end{longtable} Warning message: In print.xtable(xtable(mtcars[1:10, c(1, 2)], caption = "CARS"), : Attempt to use "longtable" with caption.placement="top". Changing to "bottom". The error seems strange since I would assume that "longtable" tables would naturally have the caption at the beginning of the table, especially if it streches over multiple pages. There is no such error when caption.placement="bottom". Would this be a bug in xtable()?
