Hello @nguyen_thuy , is there any output or log information that you can included? Do you notice any errors or warnings that it gives after you click "knit"?

[nguyen_thuy]

when I press Knit, It said "Rendering R Markdown documnts requires updated versions of following packages:rmarkdown, xfun. Do you want to install these packages now?
I pressed 'YES"
Then screen show "R Markdown Dependencies :Fail"

@qquagliano do you know how to fix this case?

[qquagliano]

It looks like you are missing dependency packages for rmarkdown.

@nguyen_thuy try running this code is your R console:

install.packages(c(
   rmarkdown,
   xfun
))

Afterwards, restart Rstudio and try knitting again. If you get another error of some sort put it here and we can troubleshoot more

Any guidance on how to troubleshoot this?

Read your error messages. They often imply or straight out suggest what to do. At the very least you can share them here so others can interpret them for you.
