I am trying to load library(xlsx) in R but getting below mentioned error:

Loading required package: rJava
Error : cannot allocate vector of size 3.6 Gb
In addition: Warning messages:
1: package ‘xlsx’ was built under R version 3.1.3 
2: package ‘rJava’ was built under R version 3.1.3 
3: In get(Info[i, 1], envir = env) :
  Reached total allocation of 4028Mb: see help(memory.size)
4: In get(Info[i, 1], envir = env) :

Error: package ‘rJava’ could not be loaded

I installed package rJava as well but get similar error while loading library rJava as well. I don't have any java knowledge. Please help how I can fix this error. I don't have java installed on my machine.

If not mistaken, `rJava` clearly needs java to be installed. – Mar 12 '15 at 05:26
@Pascal is right, you first need to install Java on your machine. – Dominic Comtois Mar 12 '15 at 05:37
And to avoid some memory limitations, add this line `options(java.parameters = "-Xmx16g")` – statespace Mar 12 '15 at 07:06
