Error using getHdf: Error in setPath

[elisabeth-huellbusch]

Hello

I am trying to download a series with getHdf():
getHdf(product="MOD13A2", tileH=18, tileV=4, begin="2000.07.01",end="2000.07.15")

While on my Linux system this works perfectly well, I get an error when trying to do the same on Windows (personally I am working with Linux, but we want to use the MODIS package in a course where the students are going to work on Windows).

Though getHdf() manages to download a couple of hdf files, it will stop at some point and give me the following error:
Updating collection from LPDAAC for product: MOD13A2
Error in setPath(path.expand(paste0(opts$localArcPath, paste0(unlist(string), : dir.create(path, recursive = TRUE, showWarnings = showWarnings) is not TRUE)

If I then repeat the call of getHdf(), it will again download a couple of hdfs and then stop again at some point and so on.

Hope you guys can help me.

Hm, I fail to reproduce this on Windows. On my machine, everything runs smoothly:

hdf = getHdf(product="MOD13A2", tileH=18, tileV=4, begin="2000.07.01",end="2000.07.15", quiet = TRUE)
hdf

Can you maybe try once again (optionally, using the develop version: devtools::install_github("MatMatt/MODIS", ref = "develop")) and also include your sessionInfo()?

I tried again using the develop version and got the same.
