There is a mailing list R-Sig-Geo which is more appropriate for
questions about the rgdal and related packages.
If by "read the information GDType" you mean to get that
"Int16"
description you can get it by delving into the attributes of the
GDALinfo return value, for example:
f <- system.file("pictures/erdas_spnad83.tif", package =
"rgdal")[1]
attr(GDALinfo(f), "df")["GDType"]
GDType
1 Byte
In your case that would be
attr(GDALinfo("MOD13Q1.A2001049.h13v11.005.2007002215512.250m_16_days_EVI.tif"),
"df")["GDType"]
If you just mean to read the data into R, then use readGDAL from the
rgdal package. Extensions to this support that simplify some matters
are available in the raster package.
Cheers, Mike.
