Dear all,

I am trying to change the size to raster maps generated in R. However, the
differently layers separate when i do this.
Any body knows if its possible and how to avoid this?
Thanks
There it goes an reproducible example

alt <- getData('alt', country='CHE')
slope <- terrain(alt, opt='slope')
aspect <- terrain(alt, opt='aspect')
hill <- hillShade(slope, aspect, 40, 270)
plot(hill, col=grey(0:100/100), legend=FALSE, main='Switzerland')
plot(alt, col=rainbow(25, alpha=0.35), add=TRUE)

Then, use image export or save in pdf, or zoom options in Rs tudio to
change the size of the file.

Thanks in advance.
Agus
