R-Latex question

Hi, maybe my question is not typical. I want to make R table-kind output to
be readable immediately in Latex but I am struggling with symbol '\' needed
for instance in '\hline'. For example when 'Table' is a matrix class object:

cat("&",Table[1,1], "&",Table[1,2], "\n");flush.console() 
cat("\hline \n");flush.console()
cat("&",Table[2,1], "&",Table[2,2], "\n");flush.console() 

etc, to have specific output which I can paste (or save) in latex readible
format.

but '\' was not accepted by R. Is there any way to over come this obstacle
or maybe other way to 'implement' R table output into latex format

thank you in advance

Double the backslashes and/or have a look at the "xtable" package.

you need to double the backslashes, as in

cat("\\hline \n");flush.console()

as in
\hline 

The warning when using just one kind of hints at what is going on:
hline 
Warning messages:
1: '\h' is an unrecognized escape in a character string 
2: unrecognized escape removed from "\hline \n" 

You may want to take a look the packages Hmisc and xtable, which both
have great facilities for doing latex output from all kinds of R
objects.
