Cannot install on the server.

[Yuanchao-Xu]

rJava works well, can be loaded. But downscaleR.java cannot be loaded.

All the packages can be installed successfully, but downscaleR.java cannot be loaded. When loading it, it will stop after loading rJava.

I use Java8u40, and R 3.1.2. all the dependencies are installed with the latest version. I install with the same condition on my personal computer and they can be loaded and used successfully. For other computers, either cannot be installed or can be installed and loaded. I never met such situation that the package can be installed but cannot be loaded.

Anybody has the same problem like this ?

Hi Diana, I do not know what is the problem. It is working fine on our server. Any hints are welcome. best regards,

Joaquín

Dear Joaquín,

When I try to install the package using the git I have the following error:

devtools::install_github(c("SantanderMetGroup/downscaleR.java","SantanderMetGroup/downscaleR")) Downloading GitHub repo SantanderMetGroup/downscaleR.java@master Installing downscaleR.java "C:/PROGRA~1/R/R-32~1.2/bin/i386/R" --no-site-file --no-environ --no-save --no-restore CMD INSTALL \ "C:/Users/hgc874/AppData/Local/Temp/RtmpuM08t6/devtools172879821987/SantanderMetGroup-downscaleR.java-357b9ec" --library="\a00143.science.domain/hgc874/Documents/R/win-library/3.2" \ --install-tests

I don't know what I'm doing wrong. Could you please help me? Regards, Diana

Then if I use the functions directly from the unzip file using for (i in list.files()){source(i)} I have the following problem:

ncep.inv <- dataInventory(ncep) [2015-09-23 11:54:50] Doing inventory ... Error in .jcall("java/lang/Class", "Ljava/lang/Class;", "forName", cl, : No running JVM detected. Maybe .jinit() would help. Error in .jfindClass(as.character(class)) : No running JVM detected. Maybe .jinit() would help. .jinit() ncep.inv <- dataInventory(ncep) [2015-09-23 11:55:06] Doing inventory ... Error in .jfindClass(as.character(class)) : class not found

Maybe this is a problem of my lack of knowledge in Java but I don't know. have you experience this before?

Any help would be really appreciated :)

[dianalucatero]

Oh! I forgot to mention, I only have the problem above with the ncep file. If I try to do the data inventory with the observations file it works perfectly.

Hi folks, two things:

• I am experiencing the same installation problems as described by Yuanchao in the first post using Windows on VirtualBox. I have to force the stop. I will try to find out the reason for this.
• For Diana's problem installing downscaleR.java, my suggestion is to download the zip file from the master and and install locally. This should work fine.

cheers

It finally worked after restarting in Windows. I found no problems with Ubuntu, nor in our server...
