Is it possible to load an RData file? #10

Closed pedromss closed 7 years ago

pedromss commented 7 years ago

I have an R script load.R that attempts to do 

load("test.RData")

When I run:

engine.eval(new FileReader("load.R"))

An exception occurs:

It looks like you don't have Renjin's dependencies on your classpath. Take a look at the documentation on project setup: http://docs.renjin.org/en/latest/library/project-setup.html

I have read the documentation and added the renjin engine dependency...

The class org.tukaani.xz.XZInputStream is part of the org.tukaani:xz:1.0 and should be on your classpath as xz-1.0.jar -- but that doesn't seem to be the case.

It looks like you're running this from Intellij. Can you take a look at the first line of the console output? It should be the command line that launches the JVM and should include the full classpath, including xz-1.0.jar.

Do you have a different, newer version of org.tukaani:xz on your classpath? The md5sum of the xz-1.0.jar should be 8c53d7a772f11a88ee95c6ed0c215e49.

Perhaps IntelliJ is out of sync with your SBT file?
