Hi, Thanks so much for developing fasterize! I've been playing around with using fasterize with terra, and I noticed that converting `RasterLayer` objects produced by `fasterize::fasterize()` into `terra::rast()` objects can...

This PR provides several fixes. These include (1) fix compatibility issues with upcoming version of the _Matrix_ package (version 1.4-2), (2) update package documentation to provide details for obtaining and...

The cplexAPI R package has been archived on CRAN. Since prioritizr uses this package to interface with CPLEX, this will cause issues for users that rely on CPLEX. I'd reached...

The rgdal, rgeos, and maptools R packages will be retired on Jan 1st 2024. So, we'll need to make sure that prioritizr fully transitions away from these packages before then.

enhancement

Add new objective for maximizing the minimum each feature is represented in the solution, see https://github.com/lizlaw/maximin-test

feature propsal

To generate a portfolio of solutions that are markedly different to inform real-world priority setting, @AnotherBobSmith suggested generating solutions with a random percentage (e.g. 20%) of selected planning units locked...

I propose adding a `add_min_size_constraints` function that would allow users to specify the minimum size a reserve can be to represent a particular feature. I think these constraints could be...

feature propsal

The `add_locked_in_constraints` and `add_locked_out_constraints` will fail--and ungracefully--when locking planning units in a multi-zone problem where some cells have NA values in a given zone and non-NA values in a different...
