Thank you Henrik and Rolf. My migraine just disappeared. : )
myobjects = ls(pattern='^RH')
dataobj = mget(myTemp,.GlobalEnv)
map = Reduce(merge,dataobj)
did the trick. do.call() didn't cut it for some reason . . . it
returned an " 'x' is missing " error. But Reduce works quite nicely for

See ?get and ?do.call. That should be enough.
?Reduce may be an alternative for do.call(), but could also be less
memory efficient.

Hello,

These rasters are sections of a continuous map, and I would like to
combine them using the RasterObject merge tool in package 'raster.'
Merge expects an input list
