Running command had status 1

Question

I've tried to run command in R 2.15.2

rsaga.geoprocessor(lib="ta_channels", module=0, param=list(ELEVATION="DEMflt.sgrd", CHNLNTWRK=paste("channels", i, ".sgrd", sep=""), CHNLROUTE="channel_route.sgrd", SHAPES="channels.shp", INIT_GRID="DEMflt.sgrd", DIV_CELLS=3, MINLEN=40), show.output.on.console=FALSE)

and I'm constantly getting this warning:

    Warning message:
running command '"C:/Users/Nenad/Documents/R/win-library/2.15/RSAGA/SAGA-GIS/saga_cmd.exe" ta_preprocessor 2 -DEM "DEM1.sgrd" -RESULT "DEMflt.sgrd" -MINSLOPE "0.05"' had status 1 

I use windows 8 and also tried to ran R as admin.

Any idea what is the problem? Thanks!

Answer 1

Running system commands from R can be really tricky. In my experience, as long as the exit code is not 127 then the command did run, and you could use the intern=TRUE switch in the system command for a more verbose output. If you run the command again, the warning message could contain a errmsg attribute as well for some more info. hth

Idk how actual it is, but I've been struggling with " had status 1 " warning a lot. Especially it got really annoying when I tried to use seasonal package to conduct the X13-ARIMA-SEATS seasonal decomposition of time series. The seasonal::seas command just doesn't work, because in the command there is a stop condition when running a certain stuff with cmd.exe returns non-zero status. While, as it was mentioned before, ' status 1 ' doesn't prevent command execution, in case of seasonal package it does.

The problem in my case was caused by some mistake in Windows Registry (Win 10), that in turn caused warning System cannot find the path specified when launching CMD.exe or PowerShell, which caused warning inside R as well. So to fix it:

1. Press Win+R -> regedit
2. In HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Command Processor folder clean the value of Autorun record (it should be empty)
3. Do the same for Autorun in HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Command Processor

After these actions annoying warning with " has status 1 " has gone and seasonal::seas started to work perfectly. Hope it will be usefull for somebody.
