I've submitted spgrass6_0.5-9.tar.gz to CRAN, so barring accidents it
should be out soon. If you're using the raster or vector plugins and have
comments, please let me know - look for the new plugin= argument, which is
FALSE by default to avoid problems, but can be NULL for autodetection, or
TRUE to force use if the plugin is known to be available.
My apologies, 0.5-9 was released on CRAN three weeks ago, so no change.
Dear Roger,
not sure what that means: can you upload only periodically from time to
time?
No, I just forgot that I had released the package with the changes, and
tried to release an identical package, but the CRAN administrator asked if
I was aware of this!
What I do need is advice on whether to leave plugin=FALSE, or to set
plugin=NULL for autodetect, and risk foobars from existing user code
assuming the current region rather than the raster region seen by the plugin
if installed and autodetected.
Let me suggest:
The raster plugin behavior will be a problem (we should really fix that in GDAL)
while the vector plugin behaves well.
How about having two parameters:
rasterplugin = FALSE
vectorplugin = NULL
?
OK, will do for next release.
My preference remains for plugin=FALSE, that is, users have to change to
NULL or TRUE themselves, and accept the consequences of mixing up regions.
Above might help.
Is there a shell-level utility in GRASS to check whether the region of a
raster is equal to the current working region - the function could call that
and create a copy of the required raster in current resolution if they
differ?
The easiest way it to compare the output of
r.info -g map127
north=230000
south=214000
east=646000
west=628000
and
g.region -g | grep '^n=\|^s=\|^e=\|^w='
n=228513
s=214975.5
w=629992.5
e=645012
But the resolution may differ too - I need a one shot comparison. Isn't
anything exposed - I've looked in g.copy and r.resample without seeing
anything. Maybe:
r.info -gs elevation.dem
g.region -g | grep '^n=\|^s=\|^e=\|^w=\|^ewres=\|^nsres='
but an internal match (where r.resample would be a no-op or not) would be
helpful.
