adimpro.options(xsize = 1280, ysize = 1024)invisible(NULL) On some systems the default X11.options()$type ''cairo'' leads to significant slower
image display. You may try to use X11.options(type=''Xlib'') instead. To automatically
choose this option set the system environment variable R_X11type (setenv R_X11type Xlib
or export R_X11type=Xlib) before loading the package.
