The package ggplot themes installs just fine, but will not run when trying to load:
Error: package or namespace load failed for ‘ggthemes’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/rstudio-user/R/x86_64-pc-linux-gnu-library/4.0/stringi/libs/stringi.so':
libicui18n.so.55: cannot open shared object file: No such file or directory
Any idea what might be causing this?
