`argument is of length zero` error in `afm_scan_files` #78

Open deeenes opened 4 years ago

Hi,

If I run font_import, after scanning all the directories, it fails with the following error:

Found FontName for 5044 fonts.
Scanning afm files in /usr/lib/R/library/extrafontdb/metrics
Error in if (grepl("Bold", weight)) { : argument is of length zero
In addition: There were 50 or more warnings (use warnings() to see the first 50)

The traceback:

5: FUN(X[[i]], ...)
4: lapply(afmfiles, afm_get_info)
3: afm_scan_files()
2: ttf_import(paths, recursive, pattern)
1: font_import()

In the /usr/lib/R/library/extrafontdb/metrics directory there are 4862 afm.gz files. Also I can run font_import only as root, is it normal?
