[R] Snowfall - Error in checkForRemoteErrors(val) with sfClusterApplyLB()

Hello, I'm trying to run a code that uses the snowfall package. Here is the structure of my code. sfInit(parallel=T, cpus = 5, slaveOutfile="ErrorMessage.txt") sfExportAll() sfLibrary(rgdal) sfLibrary(raster) sfLibrary(sp) sfLibrary(rgeos) sfLibrary(snowfall) system.time( sfClusterA

You forgot to load the required packages on the client nodes by sfLibrary(fCalendar) sfLibrary(fractalrock) and you really should not tryCatch without evaluating the errors for yourself. Best wishes, Uwe Ligges On 12.01.2011 09:47, Santosh Srinivas wrote: Hello, Just wondering why I am u

[R] snowfall on Win7

Dear list, Does the snowfall package work under Windows 7? Recently I upgraded from Windows Vista to Windows 7, and at the same time upgraded R from 2.8.1 to 2.10. On my machine (Intel i7 based) snowfall worked perfectly on my previous installation, but after the upgrade the same scripts do n

[R] snowfall: sfExport apparently harmless error

I'm running my script using mpirun -mp 4 and using snowfall+Rmpi on Linux 64bits. I receive the following error, but apparently without consequences on the results. Any idea? I'm able to reproduce it with a minimal script (below). Seems the critical issue is the for loop. Without it no error.

Re: [R] snowfall sfInit error

Dear Mr. Ripley, indeed that it true. sfInit() currently have a bug on Windows depending on the usage of the Linux tools and the broken Exceptionhandling. Too bad I never tested it accordingly on Windows (as we do not have any Windows machines in our institute). snowfall 1.62 is in the pipe
