The PNAS format requires installing extsizes
package from CTAN. Using tinytex with R Markdwn, it should install automatically if missing. For example, I got this by rendering
tlmgr.pl: package repository https://mirrors.nxthost.com/ctan/systems/texlive/tlnet (not verified: pubkey missing)
[1/1, ??:??/??:??] install: extsizes [12k]
running mktexlsr ...
done running mktexlsr.
tlmgr.pl: package log updated: C:/Users/chris/AppData/Roaming/TinyTeX/texmf-var/web2c/tlmgr.log
tlmgr.pl: command log updated: C:/Users/chris/AppData/Roaming/TinyTeX/texmf-var/web2c/tlmgr-commands.log
You can install manually using tinytex::tlmgr_install("extsizes")
or using tlmgr
at command line directly (or install the package fro your distribution (MikTeX maybe).
Anyway, format depends on some CTAN package that needs to be installed. Error log will tell you what is missing if you don't rely on automatic installation.
We don't usually add .cls
files in the templates when they can be available through a CTAN package.
Thank for reporting though.
