Fail to run "Knit to HTML"

[cheoljcho]

Dear experts,

I am successful in executing a R Markdown file in R Studio, After that, I attempt to knit it to html document. But at the end of the converting process, the error massages shown below are displayed. How can I be successful in getting the HTML document? I will appreciate any comments. Thanks.

So you have a code example? not sure if it's a code failure, maybe a latex failure or a software issue
