[GRASS-user] R-GDAL incompatible libraries

[Kim Besson]

Following Leo's suggestion I installed GDAL 1.6.3 and I tried again:

> library(spgrass6)
Loading required package: sp
Loading required package: rgdal
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.6.3, released 2009/11/19
Path to GDAL shared files: /usr/share/gdal16
Loaded PROJ.4 runtime: Rel. 4.6.1, 21 August 2008
Path to PROJ.4 shared files: (autodetected)
Loading required package: XML
GRASS GIS interface loaded with GRASS version: 6.4.0svn
and location: nc_spm_08

(seems OK?)

> precip <- readVECT6("precip_30ynormals", ignore.stderr)
OGR data source with driver: GRASS
Source: "/mnt/GIS/nc_spm_08/PERMANENT/vector/precip_30ynormals/head", layer:
"1"
with 136 features and 18 fields
Feature type: wkbPoint with 3 dimensions
(seems OK?)

When I did
> plot(nc_state, axes=TRUE)
> plot(precip30n, add=TRUE, lwd=2, col="brown")
Error: object 'precip30n' not found
Error in plot(precip30n, add = TRUE, lwd = 2, col = "brown") :
  error in evaluating the argument 'x' in selecting a method for function
'plot'
THe last plot gave that error

But would you say that it seems to be working?

Thank you all for your help and support
Thanks
Kim


Question: Is there any known problem with GRASS and GDAL1.6.3?
