when i run the examplle geo = runMrt(product="MOD11A1", extent="austria", begin="2010001", end="2010002", SDSstring="101",

occure follow errors: 'mrtmosaic' Not an internal or external command, and not a runnable program Or batch files. 'resample' Not an internal or external command, and not a runnable program Or batch files.

Before installing the modis package, do i should install mrttool from modis web? i notice that the mrttool in the modis web have retired.

I strongly recommend using runGdal() instead. runMrt() has primarily been kept inside the package to account for backward compatibility, although the software has been retired a good while ago (I believe the last update was in 2011).

If you, for whatever reason, really want to try out MRT, you'll need to retrieve the software installer from somewhere, install and set environment variables MRT_HOME and MRT_DATA_DIR accordingly. You can then verify your installation via 

MODIS:::checkTools("MRT")
# Checking availability of MRT:
#   'MRT_HOME' found: C:/MRT 
#   'MRT_DATA_DIR' found: C:/MRT/data 
#    MRT enabled, settings are fine!
