An answer was provided to this question previously, however it did not solve the question.

I am analyzing MODIS data, and would like to download and process the data. Here's what I have done so far:

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'

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

 DOWNLOAD:
 _______________
 MODISserverOrder : LAADS, LPDAAC 
 dlmethod         : auto 
 stubbornness     : high 

 PROCESSING:
 _______________
 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

As you notice above, it suggests that there is no GDAL. However, I have installed rgdal as well as:

> 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!

Any suggestions?

Followed instructions provided here and installed GDAL again on the local machine, followed by:

> 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'
