Hello all, 

I want to set (x_1, x_2, \dots, x_n) in a bold font within R documentation. I wrote 
\deqn(\bold{x}_1, \bold{x}_2, \ldots, \bold{x}_n),
but when Rstudio shows HTML preview of the documentation,  x is not 
bold and \bold{x} is illustrated instead. The other latex math bold producer such as \boldsymbol, \mathbf, \boldmath were also unsuccessful.
However, for PDF version of documentation it works.


So, What is the right command for setting a character in a bold within math for HTML version of documentation?

Thank you,

P.S.I achieved the same result with \mathbf and \boldsymbol
