I am trying to install Herper and it says it is not available for my version of Bioconductor. However, the Bioconductor website says that Herper should work with version 3.15 and R 4.2.1 which I have!

Here is my code:

if (!require("BiocManager", quietly = TRUE))
  install.packages("BiocManager")

BiocManager::install("Herper")

And here is the error I get:

> if (!require("BiocManager", quietly = TRUE))
+   install.packages("BiocManager")
Bioconductor version 3.15 (BiocManager 1.30.18), R 4.2.1 (2022-06-23)
> BiocManager::install("Herper")

'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details

A version of this package for your version of R might be available elsewhere,

Herper has failed to build since the last release on mac and linux, and therefore not yet available on those platforms. It did have a clean build on windows and the windows binary is available for that platform. See the package archive section on the Harper Landing Page and Harper Build report. We will be reaching out to the Harper package maintainer to fix the package to avoid deprecation.
