I think my version that worked was with rpy1, not 2. You should be
able to do library(rgdal) in R to see if it is loading properly.
Something like this should show up in the R console:
> library(rgdal)
Loading required package: sp
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.6.0, released 2008/12/04

1.6/Resources/gdal
Loaded PROJ.4 runtime: Rel. 4.6.1, 21 August 2008

It might be worth trying an older R binary, not 2.8.x. Perhaps the R
update breaks something.
Cheers,

I imagine most versions are hidden in there somewhere but just in
case: Qgis 1.0.0; OS X 10.5.6; R 2.8.0.
I suspect that rgdal isn't properly installed but then again, I
think that will be a problem yet to come. The near penultimate line
references rpy2. Does that indicate it is installed correctly or the
source of the problem?
Yeah, I should figure out how to do this directly via adehabitat and
ultimately I will. This would be nice to figure out all the same.

Well, you might try the plugin again. I'm using a qgis build from
the developer trunk, so things might be unstable because it's
bleeding edge.
The weird thing is that one run worked, at least partially. I
noticed that it failed on the kernel methods (or one of them at
least). I've tried a few more times today to no avail. Give it a
try on your end and let me know if it works, what versions of
everything you're using, etc.
The alternative is to do the calculations in R with the adehabitat
package (I think that's the one with home range analyses).

Wow, thanks for the quick response and follow-ups.
The mention of problem with R 2.8 was most useful as that is what
I have. Oddly, on my first attempt to install HR all went
smoothly, no errors, menus appeared and such. It was in trying to
get some data to test that I discovered the delimited text issue.
However, at some point during start-up of Qgis errors associated
with HR appeared and proved rather troublesome (selecting the
plugin menu to uninstall HR would cause the application to
freeze). Eventually during a freak error free start I uninstalled
it. That is when I realized I needed rgdal. I guess that won't be
the final solution!
At this point I'll wait for an update of HR rather than risk more
incompatibilities by stepping backward. This will give me a chance
to try to figure out installing rgdal. I'm missing something in
the proper command.
Thanks again for your help and advice. Hard to believe it but
there a couple of other newbies after me for advice!

I'm on my phone. Sorry for brevity.
I think I ended up doing the source install through R. The HR
plugin is currently not working with R 2.8. If you need it, grab
an older version or wait until it's fixed.

Hey John,
Indeed. I was crawling up the GRASS learning curve and then
along came Qgis which seems to be a gentler way into the GRASS
way of doing things (and even allows access to at least some of
the power of GRASS).
Do you have any hints as to how to install rgdal (OS X)? I'm
trying to install the Home Range plugin into Qgis and this seems
to be the primary thing I'm missing. I can get the source
through the R package installer (no binary) or the framework
from http://www.kyngchaos.com/ but I'm not really sure of what
to do from there. I suspect I can eventually sort it out (I
think rpy2 installed ok) but I get a bit nervous experimenting
in the monitor window. Tips would be welcome!

The devs are quite great (I'm just a user, myself). Stick with

the latter for heavy crunching of analytical maps. I'm quite
pleased with both.
