Hi all,

I'm using PANTHER.db to run some enrichment analysis and am trying to use the function pthOrganisms to restrict the database to mouse.  More specifically, the code is:

pthOrganisms(PANTHER.db) = "MOUSE"

However, I obtained the following error:

Error: could not find function "pthOrganisms"

The package installs just fine and the library loads correctly.  Page 3 of the vignette (https://bioconductor.org/packages/release/data/annotation/vignettes/PANTHER.db/inst/doc/PANTHER.db.pdf) shows how to use the command, and my code matches exactly.  I also tried PANTHER.db::pthOrganisms(PANTHER.db) = "MOUSE" but still obtained the same error.  Any tips on how to proceed?

Thanks very much!

You're using a very old version of R, 3.1.2 is now nearly 3 years old.  Since Bioconductor releases (and thus versions of Bioconductor packages) are tied to the R version that you are using, this means you also get very old versions of the packages.  In your sessionInfo() output you can see that you have PANTHER.db_1.0.1, but the most recent version is PANTHER.db_1.0.3

If you check the old vignette for version 1.0.1 (https://bioconductor.org/packages/3.1/data/annotation/vignettes/PANTHER.db/inst/doc/PANTHER.db.pdf) you'll see that function doesn't appear as it is a relatively new addition.

My recommendation would be to get the latest version of R and freshly install the packages you want to use.
