Hi R-people

I am trying to have R write latex-code.

do not produce similar results.  I would like to something like

write("\begin{tabular} ,file=. . .)

write("\end{tabular},file=. . .)

Hmmm. Not too clear what your problem is but if something is eating
your backslashes, chances are that you just need to double them, as in

cat("\\help\n")

\help

In some rare cases you need to redouble them, but this is not one of
them, I think....

Oh. It is one of these cases , I think:
\b means: Backspace!

To write something with "\" in it, it is much safer to double the "\"
every time.

This means that for the \\ at the end of lines of tables you need to
double each backslash.  e.g. for some tables I produced I had R code like
this ...

tabfile _ "../tex/zzq.table"
write("\\begin{table}\\label{table:zzq}\\caption[Summary of results --- simulation zzq]",file=tabfile,append=T)
write("\\begin{tabular}{|l|c|c|c|c|}",file=tabfile,append=T)
write("\\multicolumn{5}{c}{$\\hat\\la$ (true value = \\laval)}\\\\",file=tabfile ,append=T)
write("\\hline",file=tabfile,append=T)
write("method & mean & median & std. dev. & IQR \\\\",file=tabfile,append=T)
write("\\hline",file=tabfile,append=T)
write(paste('starship (K-S) &',signif(mean(ks.zzq$l1),4),' & ',
 signif(median(ks.zzq$l1),4),' & ', signif(sqrt(var(ks.zzq$l1)),4),' & ', 
 signif((quantile(ks.zzq$l1,.75)[[1]]-quantile(ks.zzq$l1,.25)[[1]]),4),
 ' \\\\ '),file=tabfile,append=T)
write("\\hline",file=tabfile,append=T)
