Using GRASS/R interface with an xy location
I am using GRASS 5.7 and R 2.0 for OS X. I have a simple xy location I
am doing some theoretical work with and would like to import maps into
R using the interface in order to do analyses. Yet when I attempt to
do this, I get the following error:
>G<-gmeta()
Error in gmeta() : region for current mapset is invalid
line 11: <top: 100>
run "g.region"
I traced the problem to the compiled C program that is called from the
gmeta R function (i.e. > .C("gmeta") gives me the same error). I
haven't been able to locate...

NA's from GRASS-package
Hello,
I run R inside GRASS and tried to obtain values of a raster file inside GRASS
but this raster image contains only a few relevant pixel and approx. 1.5
Mill. NA's, I did
G <- gmeta()
sites1 <- rast.get(G, "sites1")
df.sites1 <- data.frame(east(G), north(G), sites1, na.action=na.omit)
Error in as.data.frame.default(x[[i]], optional = TRUE) :
can't coerce function into a data.frame
executing it without na.action works fine but with 1.5 Mill. redunda...

check does not accept --vsize option (PR#481)
...Version: 1.0.0
OS: Linux 2.2.10/i686
Submission from: (NULL) (130.75.72.37)
Hi,
I wanted to "check" the R.GRASS GIS interface from Roger Bivand:
http://www.geog.uni-hannover.de/grass/statsgrasslist.html
using
R CMD check --vsize=10M GRASS
but:
[error message shortened]
> G <- gmeta()
Error: heap memory (6144 Kb) exhausted [needed 1024 Kb more]
See "help(Memory)" on how to increase the heap size.
Execution halted
It seems that --vsize is ignored. I check R/bin/check, the
parameter is sent properly to R but ignored there. From the
buglist I have seen that this...

geoR size limit problem
Hi all,
I tried to produce some kriged surfaces with geoR (latest version). The size
of the grid should be around 900 x 650 cells (what I find is not a very big
grid), and the number of points is around 2500. The command krige.conv
stopped after arround 5 min saying it can not allocate a vector with around
1.5 billion units. Sounds reasonable.
Is there a workaround? How would I partition the

matrix from sequences
Hi all,
I have a data frame with sequences of x and y from a map. I would like to
know it both ways:
1. How to make a matrix from that;
2. how to make a data frame of all points in a map.
Probably it is a silly question, but please tell me where to read about it
or tell me how to do it.

last point (optional!) about krige.G
I also tried to use krige.G from the grass package, but for the moment I have
a strange error message : (where G is obtained with gmeta() command)

Running an R script without running R
Is there any way to run an R script without running R?
As an example, suppose I have a tcl/tk interface that asks
for a number (in a GUI) and displays its factorial. Is there a
way to invoke this script without invoking R?
I'm using R 2.4.1 in GNU/Linux Fedora Core 4.

using Rterm under cygwin, no possiblity to delete characters
Dear R-users,
When I call Rterm from cygwin, I have no options but typing the exact syntax
the first time. If I happen to hit the "delete" key (backspace), R dies when
I press enter saying :
Error: ... (error concerning the function on the last line of text)

Perhaps some of you have experienced this and found work arounds? One has to
be pretty good to type without
