[R] paste in xtable

Actually the '\\textbf' specification would work just fine. If you
examine test[,1] you'll see it contains the correct thing. The
problem is when print.xtable is called. This is because it
automatically contains a function that "sanitizes" the character
entries to "fix" characters that have a special meaning in latex.
Hence \\textbf becomes $\backslash$textbf. The following should work:
test= matrix(1:4, nrow=2,ncol=2)
test = xtable(test)
test[,1] = ifelse(test[,1]>1,paste('\\textbf{',test[,1],'}'),test[,1])
print(test, sanitize.text.function=I)
The last command sets the sanitize function to do effectively do
nothing and simply return the string. Hope this helps.
