[GRASS-user] Installing spgrass6 package - Errors and warnings

[Chethan S]

Hello everybody!

I am using GRASS 6.4.0 RC6 in ubuntu 10.04. I installed R version 2.11.1
(2010-05-31) just today. As I need GRASS and R interface for my work, I went
ahead as per instructions in
http://www.osgeo.org/files/journal/final_pdfs/OSGeo_vol1_GRASS-R.pdf.

Initially when I started R from within GRASS and tried the command I got the
following errors:
> install.packages("spgrass6", dependencies = TRUE)
Warning in install.packages("spgrass6", dependencies = TRUE) :
  argument 'lib' is missing: using '/usr/local/lib/R/site-library'
Warning in install.packages("spgrass6", dependencies = TRUE) :
  'lib = "/usr/local/lib/R/site-library"' is not writable
Would you like to create a personal library
'~/R/i486-pc-linux-gnu-library/2.11'
to install packages into?  (y/n) n
Error in install.packages("spgrass6", dependencies = TRUE) :
  unable to install packages
> q()

Later I started R using "sudo R" and then the following errors and warnings
occurred.
> install.packages("spgrass6", dependencies = TRUE)
Warning in install.packages("spgrass6", dependencies = TRUE) :
  argument 'lib' is missing: using '/usr/local/lib/R/site-library'

If you have installed the GDAL libraries, then make sure that
gdal-config is in your path. Try typing gdal-config at a
shell prompt and see if it runs. If not, use:
 --configure-args='--with-gdal-config=/usr/local/bin/gdal-config' echo with
appropriate values for your installation.

The result is I am not able to use spgrass.

Error in library(spgrass6) : there is no package called 'spgrass6'

As an intermediate level user in terms of commands and also regarding R and
GRASS packages I am not able to decide what went wrong. Can you please help
me out.
