[Qgis-developer] problems with SDA4PP plugin

[Giovanni Manghi]

Hi Volkan,

very nice the idea to add the R package installer in the plugin.


I'm noticing the following:

*) the R package installer does not seems to "see" that the necessary
packages were already installed (using the R console).

*) after installing the packages, with the R package installer, it keeps
saying that iplots and rggobi are not installed (under Seven) or that
rgdal and rggobi are not installed (under xp).  Trying install again the
"missing" packages (even after removing the package folders in the R
library folder) does not seems to help.


cheers
