[Qgis-user] Re: Manage R

[Alessandro Sarretta]

Hi Carson,
I tried to use the Ctrl+F command in the manageR interface to export a R 
layer to a file, but I had this message:
Unable to find R package 'rgdal'.
but using R interface I installed rgdal and I can load it without 
problem (with "library(rgdal)" command).
If I use "library(rgdal)" in the manageR interface I have this message:
Errore: caricamento pacchetto/namespace fallito per 'rgdal' (in italian)
Error: loading package/namespace failed for 'rgdal' (in english)

The Ctrl+M command works fine.
What could be the problem?
I'm using QGIS 1.0.1 (OSGEO installer) and R-2.7.0 in Windows XP.

About this problem, I updated the plugin and now it's works: the fields 
are in the original order!
Thank you very much!!!
