yes barry I really need this.

I tried to use raster or rgdal but with poor results.

I have this function:

VGM_PARAM_A3 <- gstat(id="bos_bison",
formula=combusto~1,locations=~coord_x+coord_y, data=archezoology_table,
nmax = 10)

VGM_PARAM_A3 <- gstat(VGM_PARAM_A3, model=vgm(1, "Sph", 5, 0),
fill.all=TRUE)

ESV_A3 <- variogram(VGM_PARAM_A3, map=True, with=0.1, cutoff=9)

VARMODEL_A3 = fit.lmc(ESV_A3, VGM_PARAM_A3)

plot(ESV_A3, threshold = 5, col.regions = bpy.colors(), xlab=, ylab=,
main="Map - A3")
png("C:\Users\User\pyarchinit_R_folder\A3 semivariogram_map.png",
width=10000, height=10000, res=400)

I make a png file but how can I convert it in ascii-grid?

thanks
