Hi It seems that you need to set an environment variable used by programs in ~/MRT/bin. I don't have this installed so please have a look for some README files in ~/MRT or other places to find which value the variable are supposed to have.
In R before calling reprojectHDF() do a: Sys.setenv(MRT_DATA_DIR = "to_some_value, probably: ~/MRT/data or something like that") Hope that helps.
