No. As I said before, all I see when I enter myMap at the console prompt is a
set of RGB values displayed, not as a graphic item but rather as a character
matrix with [1:78,1:1280]-entries.
…. omitted a thousand lines of output
[76,] "#384435" "#3B4A38" "#485242" "#384435" "#243223" "#243223"
[77,] "#424C3D" "#3B4A38" "#424C3D" "#3B4A38" "#2E3C2E" "#243223"
[78,] "#424C3D" "#3B4A38" "#3B4A38" "#384435" "#324432" "#2E3C2E"
[ reached getOption("max.print") -- omitted 1202 rows ]
Kind of a PITA.
