v.krige is installed with GRASS 7 but does not run.
When you attempt to start it from the menu, it raises an error:
"ERROR: Required parameter <column> not set:
(Name of attribute column with numerical value to be
interpolated)."
When you try to run it from the command line, it raises an error:
"Loading packages, please wait...
Rpy2 not found. Please install it and re-run."

I reported this issue (for 6.5) in mailing list in January. It turned out
to be a default behaviour when a vector map without proper column data is
active when this command is performed. I noticed it on my sample data, but
another data were Ok. To tell the truth, I don't know what exactly
'column' means in this context as during creating a new vector layer from
my sparse data I didn't notice any option for that.

Comment (by cmbarton):
It turns out that there seems to be dependency after dependency for this.
I had to update R from 2.9 to 2.10 to install Rpy2. Next, I had to install
gstat and its dependencies. Now it looks like I need to install spgrass6.
When will it end? I don't yet know.

Well, spgrass6 is not in the R package manager. So where is it? Let's
pretend I'm a GIS professional who is trying GRASS for the first time and
I see a menu entry for "ordinary or block kriging". I'd be pretty
frustrated right now--especially since there is no information in the
launch failure error message to say that you also must install R.

Comment (by hamish):
I assume it is installed in the usual R/CRAN command line way with
install.packages("spgrass6"). Or in the R-GUI click on Packages, Install
package(s)..., pick a mirror, then select the package.
FWIW the dependencies are listed in the help page and this is still just
new code in the development branches so the need for a little extra shine
here and there is to be expected.

Comment (by cmbarton):
I do appreciate the pointers. However, spgrass6 will not install because
rgdal won't install--and maybe other errors besides.
Easy access to the manual is in the module GUI. But the module GUI won't
launch without the many dependencies. So you need to look it up elsewhere
to try and figure out why.
I think it is great to have kriging available for GRASS. But I'm beginning
to think it is somewhat premature to ship it with the main GRASS
distribution and in the menu when it not only will not run with the normal
GRASS dependencies, but takes a LOT of external dependencies and special
compilations to even get it to launch.
A very positive thing about GRASS is that it is possible to enhance it in
many ways, and that an increasing number of sophisticated packages are
available in the addons library to do this.
However, I worry about having items in a standard GRASS distribution,
particularly items in the menu, that don't work out of the box. And
especially items in the standard distribution that require this much work
to get to run.
To install rgdal on mac osx i need to install rgdal manually from the terminal instead of use the gui,
beacouse the gui method fails to find gdal and proy libs and include.
when tring to install from the gui, scorll the "log" and look for the web address for rgdal
(see also a section in the log where it suggest to install rgdal manually
adding the " --configure-option " string)
then :
wget ...rgdal.tgz
and insyall it manually from a shell using :
R CMD install /path/to/rgdal.tgz --configure-options="add here the path to proy and gdal"
i hope this can help.
note.
William has a binary packages for rdal
you cn also give a it a try.

Comment (by aghisla):
Hi all,
the dependency tree of v.krige is its biggest weakness. The installation
of all software is platform-dependent, can be perfomed in several ways,
and I found lot of problems related to rpy2 code.
Sorry I had very little time to work on that, after integration of v.krige
in trunk.
What about removing v.krige from main code until dependencies are better
handled? Alternatively, can it be turned into an optional module?

Anne,
I agree with this idea. You've done a lot of work on this and I'm sure
that these issues will ultimately be solved. But until then, I think it's
better in the addons. As good as it is to have a krige module, it is
better to make it an optional install than to have it a default install
and not work.

hm, is it really necessary? No way how to solve the problem without moving
the module to addons and the back? Martin
the list of dependencies takes a few iterations to get past, but after
following the R+GRASS install instructions on the GRASS wiki, and after
that is working
install.packages("put-pkg-name-here")
in an R session for all the ones v.krige complained about missing.
As commented earlier in the ticket, probably explicitly listing them in
the v.krige man page, and as a footer section in the GRASS wiki's "R" page
will help folks get through them quickly. I wonder how we could automate
that more?

I do get one error now when I run it in grass7:
{{{
[...]
Checking rgeos availability as gpclib substitute:
TRUE
Loading required package: automap
GSelect: invalid item: descriptor 'lower' requires a 'unicode' object but
received a 'str
}}}
We've seen that before in the main wx.gui, and ISTR it's an easy fix. I'm
using `LANG=C`.
thanks,
Hamish
ps- trac-tip: if you comment or change a ticket you're automatically added
to the cc-list. If you take ownership you have to then manually add the
grass-dev ML to the cc-list.
pps- do you lose anything by using the free-for-all-use rgeos cran package
versus the first-tried free-for-commercial-use gpclib cran package? aka
why not make rgeos the default?

Hello Hamish,
sorry for delay and thanks for testing.
Please see if r46642 is clearer now, then I will also add comments on "R"
wikipage.

I'm using `LANG=C`.
I can't replicate this error, when does it appear?
I run trunk compiled now (r46642).

Not at all, I added it as dependency (r46643), so that gpclib is no more
required.
