Dear friends,
I received clang-san error messages for all vignettes that include ggplot2
figures when submitting an R package to CRAN. Please see below for an
example.
How can I resolve this problem without replacing the ggplot2 figures with
base R plots?
Thank you in advance for your help.
Regards,
Kaifeng
