Error en GDAL para la biblioteca MODIS en R

Question

Se ha dado una respuesta a esto pregunta anteriormente, sin embargo no resolvió la cuestión.

Estoy analizando los datos de MODIS, y me gustaría descargar y procesar los datos. Esto es lo que he hecho hasta ahora:

library(MODIS)

MODISoptions(localArcPath = "C:\\Users\\rameshv\\Downloads\\MODISDownloads\\",
         outDirPath = "C:\\Users\\rameshv\\Downloads\\MODISOutputs\\")

'outDirPath' does not exist and will be created in 
'C:/Users/rameshv/Downloads/MODISOutputs/'
 'MRT_HOME' not set/found! MRT is NOT enabled! See: 
 'https://lpdaac.usgs.gov/tools/modis_reprojection_tool'

  localArcPath : C:/Users/rameshv/Downloads/MODISDownloads/ 
  outDirPath   : C:/Users/rameshv/Downloads/MODISOutputs/

 GDAL           : Not available. Use 'MODIS:::checkTools('GDAL')' for more information! 
 MRT            : Not available. Use 'MODIS:::checkTools('MRT')' for more information! 
 pixelSize      : asIn 
 outProj        : asIn 
 resamplingType : NN 
 dataFormat     : GTiff

Como se observa arriba, sugiere que no hay GDAL. Sin embargo, he instalado rgdal así como:

> MODIS:::checkTools('GDAL')
 Checking availability of 'FWTools/OSGeo4W' (GDAL with HDF4 support for Windows):
  OK, 'gdalinfo' is not recognized as an internal or external command, operable program or batch file. found!

¿Alguna sugerencia?

Siguió las instrucciones proporcionadas aquí e instalé GDAL de nuevo en la máquina local, seguido de:

> MODISoptions(localArcPath = 
"C:\\Users\\rameshv\\Downloads\\MODISDownloads\\",
+              outDirPath = "C:\\Users\\rameshv\\Downloads\\MODISOutputs\\")
'outDirPath' does not exist and will be created in ' 
'C:/Users/rameshv/Downloads/MODISOutputs/'
  'MRT_HOME' not set/found! MRT is NOT enabled! See: 
'https://lpdaac.usgs.gov/tools/modis_reprojection_tool'
