You could do an attribute SOP to first rename myData to myDataOrig,
then attribcreate myData as a vector, setting the values to $myData1,
$myData2, $myData3, then an attribute SOP to delete myDataOrig.
Or, you could do exactly this in VOPs (probably faster) but you'd
still need to follow it up with an attribute SOP to delete the original.
Or, you could use the unix SOP in ascii mode:
sed 's/myData 3 float/myData 3 vector/'
This will simply retype the attribute in the header of the geo
without ever reading it into Houdini.
