After a long sufferance I had succeeded in installing R GUI on my Linux/SuSE system. It worked fine. Unluckily a system upgrade patch messed up my monitor so I had to reinstall SuSE 10.3 and every other application on top of it. I have R running back with text interface. I tried to get the nice R GUI up & running again. I followed all the steps to reinstall the R GUI but this time I get a

Hi, I have a MapReduce Java code, which I am calling from R using rJava. I have prepared the R package and tested that successfully. But when I deployed the package in a cluster and executed it, I am getting ClassNotFoundException. If I run the same job directly without integrating with R, it runs perfectly. Here is my R code: library(rJava) muMstSpark <- function(mesosMaster = NULL, input =

What do all of you do out there? I would envision a situation where each night a script is run by cron that
