For quite some time, AI had kept it's grubby little hands out of the music production world. Now, a good percentage of the plugins (a plugin is a piece of software you can "plug in" to an audio track to add effects or generate audio) I see are advertised as "using AI". From reverb removers (yes, that's right, you can now remove the reverb from an audio recording), to EQ analysers. Today we'll focus on stem separation.

From a purely design aspect, Quarto's standard output for PowerPoint falls short. You're limited to seven layout options, with the most complicated being "Two Content". The {officer} R package provides a great alternative, for those seeking total control and customisation.

Positron is the new beta Data Science IDE from Posit. Though Posit have stressed that maintenance and development of RStudio will continue, I want to use this blog to explore if Positron is worth the switch.

Regular expressions. How they can be cruel! Well we're here to make them a tad easier. To do so we're going to make use of the {stringr} package. We're going to use the str_detect() and str_subset() functions. In particular the latter. str_detect() is used to detect whether a string contains a certain pattern.

Given that I do quite like twitter, I thought it would be a good idea to right about R’s interface to the twitter API; {rtweet}. As usual, we can grab the package in the usual way. We’re also going to need the {tidyverse} for the analysis, {rvest} for some initial webscraping of twitter names, {lubridate} for some date manipulation and {stringr} for some minor text mining.

Let’s get something straight, there isn’t really any trouble with tibbles. I’m hoping you’ve noticed this is a play on 1967 Star Trek episode, “The Trouble with Tribbles”. I’ve recently got myself a job as a Data Scientist, here, at Jumping Rivers. Having never come across tibbles until this point, I now find myself using them in nearly every R script I compose.

The {plotly} package. A godsend for interactive documents, dashboard and presentations. For such documents, there is no doubt that anyone would prefer a plot created in {plotly} rather than {ggplot2}. Why? Using {plotly} gives you neat and crucially interactive options at the top, whereas {ggplot2} objects are static.

As time goes on, your R scripts are probably getting longer and more complicated, right? Timing parts of your script could save you precious time when re-running code over and over again. Today I’m going to go through the 4 main functions for doing so.
