[R] a question about "latex" in Hmisc

[Shi, Tao]

Hi Erik,

Thanks for the quick reply!

My attachment was in .png which should be supported by the list ....  I'm resending it.

Yes, I knew by assigning it to an object, I can avoid this.  But, I'm curious to know what if I choose to do e.g. just latex(x), how can I get rid of the error window.  It actually worked for me once (i.e. I got Yap poped out to preview the table I'm generating), but I had no idea what I did differently.

...Tao

Your attachment did not come through, most likely because it

Well I can't directly help you with your issue, since I

As for what your
