How to remove the % lines in xtable table output by Knitr

Question

By using xtable and knitr, I add a table to my RMD document and export to PDF file.

```{r, results=\'asis\'}
library(xtable)
xtable(matrixtable)
````
         


        

Answer 1

The inclusion of the comment in the final table is defined by the comment argument to print.xtable

the default value for this is getOption('xtable.comment',TRUE).

so, if you set

options(xtable.comment = FALSE)

then for any future tables this comment will not produced.

Answer 2

You can put in directly in the print statement like so:

xtb=xtable(...)
print(xtb, comment=FALSE)
