Hello,
First please keep in mind I am not a programmer and know very little about R. I
am running the 64bit version of R on a Windows 8.1 machine. I am trying to run
a script (which I have successfully run in the past) to download some weather
data from a NOAA ftp site.
When I attempt to run the following command: system("wget -P data/raw
ftp://ftp.ncdc.noaa.gov/pub/data/noaa/2013/724620-23061-2013.gz";)
it returns status 127, which as I understand simply means the command will not
run.
If I go directly to my command prompt in Windows, navigate to my working
director, and run wget -P data/raw
ftp://ftp.ncdc.noaa.gov/pub/data/noaa/2013/724620-23061-2013.gz
the command runs and the file downloads without a problem.
Playing around, it seems I can't invoke any system commands from R. Even a
simple system("dir")
returns status 127.
I have moved to a new computer since I last successfully ran this script...I'm
wondering if this might be a permissions issue or other security setting
preventing me from invoking system commands.
Any ideas?
-Matt
