Round up of things I found interesting.
gsignal is an R package that is an improvement over the signal package. The signal package is a group of signal processing functions like you might find in Matlab. It was helpful but was missing some common functions, and some functions did not play well with complex numbers. The gsingal packaged added some key functions and works with complex numbers. It has the poly function but seems to be missing the roots function.
Ventura, the new mac operating system, is available. I'm going for it. Wish me luck!
Copilot is an app that helps write code. It uses what you wrote to suggest code snippets as you write the code. It looks interesting; I'm going to give it a try.
