Hello,

Could someone please tell if there is a way to append header info to the top of an exported dataframe (exported with write.table).  I want to append the following, which are the defininitions for an asciigrid:

ncols         532
nrows         999
xllcorner     510465
yllcorner     4766375
cellsize      30
NODATA_value  -9999


Thanks very much,

femke
