load_layers("BO_damean") gives error in .rasterObjectFromFile #16

Closed LennertSchepers closed 2 years ago

We received user feedback through mail from @MireiaValle:

load_layers("BO_damean")
trying URL 'http://www.lifewatch.be/sdmpredictors/BO_damean_lonlat.tif'
Content type 'application/zip' length 8300862 bytes (7.9 MB)
==================================================
downloaded 7.9 MB

Error in .local(.Object, ...) : 

In addition: Warning message:
In get_datadir(datadir) :
  file.path(tempdir(), "sdmpredictors") will be used as datadir, set options(sdmpredictors_datadir="<directory>") to avoid re-downloading the data in every session or set the datadir parameter in load_layers
Error in .rasterObjectFromFile(x, objecttype = "RasterBrick", ...) : 
  Cannot create a RasterLayer object from this file.

-> Feedback from @bart-v: If you just unzip the file (so you have a TIF file), before doing rasterObjectFromFile() this should work.

I suspect you just need to reinstall the package.

We launched recently a new version of the package, being the diffuse attenuation one of the updated layers. The URL http://www.lifewatch.be/sdmpredictors/BO_damean_lonlat.tif does not exist anymore. It redirects to https://bio-oracle.org/data/1.0/BO_damean.zip. The new version of the package handles zipped files. There is more information here: https://github.com/lifewatch/sdmpredictors/releases/tag/v0.2.10

@MireiaValle Can you check the version of the package you are using and reinstall if this is older than 0.2.10? 

packageVersion("sdmpredictors")

Let me know if this solves the issue.

As a side note to inform other people in the future; if handling the zipped files is new, can we update the release notes to include that? and I read "Currently uses layers from bio-oracle.org and lifewatch.be", but the news mentions that it uses the files from bio-oracle.org?

I was using version 0.2.9, I updated it to 0.2.10 and now everything works! Thank you very much for your help @salvafern, @LennertSchepers and @bart-v. Best wishes!
