I am having difficulty loading and installing the xlsx package. The
loading occurred without any problem, however the library command
library(xlsx) produced an error related to rJava. I tried to install
rJava seperately, re-loaded the xlsx package, and entered the
library(xlsx) command but received the same error message about rJave.
Please see terminal messages below. Any suggestion that would allow me
to load and run xlsx would be appreciated.
Thank you,
John
