[R] question about message

[Jeff Newmiller]

a) This is not the RStudio support forum

b) Don't post using HTML on this list. It messes up R code. Truly.

c) You have quoted a snippet of instructions to follow, but not provided what you actually did.

d) You also include errors having to do with knitr and latex, which seem unrelated to the instructions you snipped. You may well be having some problems we can help you with,  but we cannot tell from this info.

Please read the Posting Guide (see the footer), and read about making reproducible examples [1], and learn which question you really want to ask and ask it in the correct forum. You may find it easier to distinguish RStudio problems (off topic here) from R problems (on topic here) if you use the RGui program to get things working at first.
