Re: [GRASS-user] R-GDAL incompatible libraries

[Leo Hardtke]

Kim you have to plot the R object precip, not the grass vector precip30n plot(precip,lwd=2, col="brown") should work!

Thank you all for your help and support Thanks Kim Question: Is there any known problem with GRASS and GDAL1.6.3? 2010/3/2 Kim Besson <kimbesson1...@gmail.com> Ok I reinstalled rgdal R CMD INSTALL rgdal And then: R library(spgrass6) Output: Loading required package: sp Loading required package: rgdal Geospatial Data Abstraction Library extensions to R successfully loaded Loaded GDAL runtime: GDAL 1.5.4, released 2009/01/07 Path to GDAL shared files: /usr/share/gdal15 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: North-Carolina precip30 <- readVECT6("precip_30ynormals", ignore.stderr=TRUE) ERROR: Incompatible library version for module.

R version 2.9.2 (2009-08-24) Any idea of what might not be compatible?

You also need to update the GRASS-GDAL plugin.
