"R Extension - runs but..."

alien

Hi

I have the R extension running (Ubuntu 64 bit), however any R graphics commands in the embedded R console result in the error message:

>>>Error in plot.new() : no active or default device

However plotting works fine in the standalone R.

The rapidminer startup log shows an error

but i'm not sure where the config.log file is to understand the root cause of the error. The java I am running is as below. Is the use of openjdk a problem? Or just privileges? I'm not launching rapidminer under sudo.


$ sudo R CMD javareconf

Done.


Many thanks in advance!

Hi,
it seems that during the installation of the R Package JavaGD the compiler causes an error. The Compiler is used because there are no precompiled binaries for your platform. Since I'm not a unix expert, I don't know where the GCC puts the log file.

To pursue this error, you could start R and install the JavaGD package manually there. This rules out RM related issues. Might be root privileges would help...

Greetings,
