Error #02

[user-amcc]

Hi,
I am having some issues getting the R extension to work. I am using:
Netlogo 6.2.2
RStudio (R 4.1.2)
Java 1.8.0_321
Windows 10 (64bit)

I wish to use the R extension and so I have followed the instructions for the user.properties. I have set them as follows:
r.home=C:/Program Files/R/R-4.1.2
jri.home.paths=C:/Users/username/Documents/R/win-library/4.1/rJava/jri
r.lib.paths=C:/Users/username/Documents/R/win-library/4.1

I have added the path under advanced system settings as required (https://ccl.northwestern.edu/netlogo/6.0/docs/r.html#windows-specific-installation-steps).

My R code is taken from RNetLogo as follows:

#libraries
library(rJava)#NetLogo runs on Java
library(JavaGD)
library(CommonJavaJars)
library(RNetLogo)#Our simulation package
library(parallel)#for parallelisation

nl.path <- "C:/Program Files/NetLogo 6.2.2/app"

NLStart(nl.path, gui=TRUE, nl.jarname='netlogo-6.2.2.jar')

I get the following but a NetLogo window opens:
Unable to locate empty model: /system/empty.nlogo

When I 'check' extension [r] in NetLogo I get:
Error #2: Cannot find rJava/JRI. The R Extension was unable to locate your installation of rJava

I am a little confused as when I save my users.profiles (as specified above) in the following location:
C:/Users/username/AppData/Roaming/NetLogo/6.2/r
I get:
Exception in thread "Thread-3" java.lang.OutOfMemoryError: Java heap space

Note, I have not loaded any model and it is on some kind of loop as it continuously sends this message until I quit RStudio.
I also tried changing the the .cfg file's [JVMOptions] but this did not help.

I have tried another solution related to the JGR package in R but still no joy with using the extensions [r] command in Netlogo.

Any guidance is greatly appreciated.
