Java On For R Software Needs Java

Not the answer youre looking for Browse other questions tagged java r rstudio rjava macos-high-sierra or ask your own question.

In addition, loading rJava or any package that depends on rJava (e.g., xlsx ) caused RStudio to crash (R also crashed when I tried this by opening R.app directly).

Error:.onLoad failed in loadNamespace() for rJava, details.

I tried setting it to the following (per this SO question ).

In addition, when I quit RStudio, it would seem to close normally, but then an RStudio quit unexpectedly message would pop up, indicating that the program had crashed while trying to close.

Java On For R Software Needs Java

Now, when I opened R or RStudio the This software needs Java 6 pop-up message no longer appeared.

However, I was still getting the.onLoad failed in loadNamespace() for rJava error message posted above.

It turns out that on the command line, loading rJava or any package that depends on rJava works and does not throw any errors.

However, Id like to find a way to fix the underlying problem, whatever it may be, so that RStudio can be opened in the usual Mac way, without needing a command line kludge.

Im also concerned that having an old version of Java installed could cause problems down the road.

Ive wrote a blog post regarding this issue and described this problem there.

The final step to allow starting RStudio through FinderSpotlight was to link libjvm.dylib to usrlocallib.

It still works on macOS Sierra 10.12.5 and Java Version 8 Update 141.

Additionally I had to add a symlink in the R framework to the usrlocalliblibjvm.dylib file, since usrlocallib doesnt seem to be on the rpath.

The accepted answer is probably a better option.

I tried with other solutions found around but this was the one that solved my issue.

Tried this since first since it appears simplest (and earlier efforts with directions for installing Java runtime 1.6 had not solved the problem) and immediate success with pkg:rJava and dependency pkg;XLConnect.

May need to install the legacy Java 1.6 that is available from Oracle and linked from the Apple page.

The linking of libjvm.dylib into usrlocallib made it also start:).

In my case (Mac OS.

Mojave) I had installed jdk-13 which was tested against jdk-11.

Im sure there are more than one solution to this problem and I sincerely thank them all for their contributions because sometimes one line like the one below saves a lot of time from going to trash.
