[Qgis-user] Problems with R script in sextante

[Agustin Diez-Castillo]

Hi,
I'm trying to reproduce an script published in Rbloggers [1] with no
success so far. Simpliying it do not improve the result. No png seems to be
drawn. The provided raster histogram works.

##layer=raster
##Tools=group
##dens_or_hist=string
##showplots
library('rpanel')
library('rasterVis')
str <- dens_or_hist
if (str !='dens' & str != 'hist'){

rp.messagebox('you must enter "dens" or "hist"', title = 'oops!')
} else {
    im <- stack(layer)

    if (str == 'dens') {

    densityplot(im)
    } else if (str == 'hist') {

    histogram(im)
  }
}

-------------------------------------------------------------------------

##layer=raster
##showplots

library('rasterVis')

densityplot(layer)
