[R-sig-Geo] importing and viewing a JPEG2000 file

[Edzer Pebesma]

Try readGDAL in package rgdal. On my machine, gdalDrivers() returns

...
35  JPEG2000      JPEG-2000 part 1 (ISO/IEC 15444-1)  FALSE  TRUE
...
as one of the available drivers. Then, look into
?image.SpatialGridDataFrame (package sp) and check the red/green/blue 
arguments.
