I can install rJava seemingly fine from Rstudio:
install.packages("rJava")
trying URL 'https://cran.rstudio.com/bin/macosx/contrib/4.1/rJava_1.0-6.tgz'
Content type 'application/x-gzip' length 1138672 bytes (1.1 MB)
==================================================
downloaded 1.1 MB
The downloaded binary packages are in
/var/folders/qz/9s5hs9ss00z2yzj_r2668_3c0000gn/T//RtmpqNOAbP/downloaded_packages
But when I then try to call it from the library I get the following error:
library(rJava)
Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:

error: JVM could not be found
In addition: Warning messages:

2: In fun(libname, pkgname) :

Install Java and/or check JAVA_HOME (if in doubt, do NOT set it, it will be detected)

I have installed the latest version of Java and my R is version 4.1.2. I'm using Mac.
If anyone knows how to help I would be very grateful.
Thank you!
