Hi R gurus Got an issue risen by CRAN about using unknown characters from Latex.
Here is the error message, in the context of PDF generated form manual pages *Check: PDF version of manual, Result: WARNING LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! Undefined control sequence. <recently read> \blacktriangleright * * l.237 STRATUM $\blacktriangleright $ LAYER\_3 ! Undefined control sequence. <recently read> \blacktriangleright * * l.239 PHASING $\blacktriangleright $ RUN ! Undefined control sequence. <recently read> \blacktriangleright * * l.241 INTENT $\blacktriangleright $ FEEDBACK* I understand that the \blacktriangleright is an unknown control sequence from latex ... and that sounds strange to me, as I uses it often in vignettes without any issue so far. I did some tests on my machine with R CMD Rd2pdf --force --output=x.pdf man/*.Rd and it reproduces the issue. In the incriminated manual page, the code generating this sequence is the following *\ifelse{latex}{\out{$\blacktriangleright$}}{\ifelse{html}{\out{▶}}{\u25b6}}* Apparently I need to add the \usepackage{amssymb} to the manual page. Do not know yet, how to achieve this. Yours ideas and hints welcome and this point or any other solution to this tricky issue. I know that I can still change *\backtriangleright* with any available control sequence and it will work. Indeed, not the way I prefer. Really wish to get my *\blacktriangleright* display. Best.
