在R中读取hdf4文件

Question

I have some hdf4 files which I want to read in R.

I came across this answer to use gdalUtils package. But the following code gives me a warning and it doesn't work.

gdalinfo(file.path)
NULL
Warning messages:
1: In gdal_setInstallation(ignore.full_scan = ignore.full_scan, verbose = verbose) :
 No GDAL installation found. Please install 'gdal' before continuing:
- www.gdal.org (no HDF4 support!)
- www.trac.osgeo.org/osgeo4w/ (with HDF4 support RECOMMENDED)
- www.fwtools.maptools.org (with HDF4 support)

2: In gdal_setInstallation(ignore.full_scan = ignore.full_scan, verbose = verbose) :
  If you think GDAL is installed, please run:
gdal_setInstallation(ignore.full_scan=FALSE)

This suggestion also didn't work gdal_setInstallation(ignore.full_scan=FALSE)

Do you know of any other package or way to read HDF4 files in R?

Answer 1

For Mac users : I had the same issue. I followed the instructions here .

Which consisted of downloading the most recent GDAL framework from here .

and then running the command:

echo 'export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH' >> ~/.bash_profile
source ~/.bash_profile
