I'm using XLConnect with Java on a 64 bit platform. Even after adding

options(java.parameters = "-Xmx4g")

I'm unable to load a 22MB file with extension .xlsx in R.

Some people have suggested openxlsx package but as far as I know, it makes use of rJava as well.

physical memory at your machine? `sessionInfo()` as well? – amonk May 22 '17 at 12:25
openxlsx doesn't use rJava. It uses Rcpp instead. You can see there: https://cran.r-project.org/web/packages/openxlsx/openxlsx.pdf – Sabri Karagönen May 22 '17 at 12:29
