Hi,

r2excel doesn't have anything to do with Bioconductor, so this isn't the right forum to ask about it. It would appear though that r2excel depends on the xlsx package and you don't have xlsx installed properly yet. xlsx in turn depends on rJava. So, if I were you, I'd go right back to

library(rJava)

and start trouble-shooting from there. Once you get that to work, you can see if

library(xlsx)

works. Only then would you have any chance of installing r2excel.

If you have problems, write to the authors of those packages, or use the github issues forum for those packages.
