Dear Everyone,
I am using R 2.6.2 on my Redhat AS4. I installed the RPM offered on the cran
website. I would like to use R from my bash console with the following command:
/path/to/R --vanilla --slave --args < /data/myscript.R
this script invokes a range of functions and tools, among others to process a
bunch of raster images in a loop using GDAL. The thing is that releasing this
command in the bash results in the following error
Error in function (handle) :
GDAL Error 1: TIFFReadDirectory:/tmp/RtmpPCALnL/file265f67a6: cannot
handle zero scanline size
Calls: <Anonymous> -> .Call
Execution halted
The scripts halts, although there are more images to process. The question is
why the script halts and why the script is not halted (but still "decorated"
with errors) when releasing it within the R console like so
R CMD source("/data/myscript.R")
The result of this R CMD is shown below. Note that the script is doing what it
is supposed to, despite the error it produces. The loop is completely finalized
Error in function (handle) :
GDAL Error 1: TIFFReadDirectory:/tmp/Rtmp6gXG5W/file67e9e074: cannot
handle zero scanline size
[1] "/data/someimg1.tiff"
Error in function (handle) :
GDAL Error 1: TIFFReadDirectory:/tmp/Rtmp6gXG5W/file21e4ef74: cannot
handle zero scanline size
[1] "/data/someimg2.tiff"
Error in function (handle) :
GDAL Error 1: TIFFReadDirectory:/tmp/Rtmp6gXG5W/file67e9e074: cannot
handle zero scanline size
[1] "/data/someimg3.tiff"
etc.
Obviously, the tmp directory is being deleted before the stored image in it can
be used. Does anybody know what to consider or provide when working in a
external console like bash and/or does anybody know about such halted
executions when working with GDAL?
Help is greatly appreciated,
Ciao,
Chris
