library(xlsx) fails with an error: Error: package ‘rJava’ could not be loaded
You might want to try readxl instead, as it doesn't have any external dependencies. Hadley On Sat, Apr 18, 2015 at 3:07 PM, John Sorkin

Windows 7 64-bit R 3.1.3 RStudio 0.98.1103 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
