Dear R-Devel subscriber,
I encountered the following problem for tex-formatted table with xtable(). Suppose I do want the following matrix as a table in LaTeX:
library(xtable)
a11 <- "\\color{green}\\textbf{big green}"
a21 <- "\\color{red}\\textbf{big red}"
a12 <- "\\color{green}green"
a22 <- "\\color{red}red"
A <- matrix(c(a11, a21, a12, a22), nrow = 2, ncol = 2)
colnames(A) <- c("big", "normal")
rownames(A) <- c("green", "red")
A
xtable(A, vsep=c('@{\\hspace{0.1cm}}', rep('@{\\hspace{0.4cm}}', 6), '@{\\hspace{0.1cm}}'))
I do get the following output:
% latex table generated in R 2.5.0 by xtable 1.4-3 package
% Fri Apr 27 13:19:43 2007
\begin{table}[ht]
\begin{center}
\begin{tabular}{rll}
\hline
& big & normal \\
\hline
green & $\backslash$color\{green\}$\backslash$textbf\{big green\} & $\backslash$color\{green\}green \\
red & $\backslash$color\{red\}$\backslash$textbf\{big red\} & $\backslash$color\{red\}red \\
\hline
\end{tabular}
\end{center}
\end{table}
Please, note that the curly braces are prefixed with a backslash and the double backslashes are interpreted as math backslashes. The above code snippet worked fine in R 2.4.1 and I reckon that this behaviour might be due to:
o There is a warning if \ is used unnecessarily in a string when
being parsed, e.g. "\." where probably "\\." was intended.
("\." is valid, but the same as ".".) Thanks to Bill Dunlap
for the suggestion.
Anyway, has somebody else encountered this problem and/or is so kind and give me some hints/pointers to circumvent this problem?
Many thanks in advance,
Bernhard
