dear R user,

I am trying to merge three raster ascii grid format (raster1.asc,
raster2.asc, raster3.asc) and save a new ascii grid with

merge(x, y, ..., tolerance=0.05, filename="", overwrite=FALSE,
filetype='raster', track=-1 )

of raster package but I am a very brand new of this package. could you help
me to understand better this function?

thanks

Gianni
