RStudio is the premier integrated development environment for R. RStudio for macOS is available in open source and commercial editions and runs on the desktop (Windows, Mac, and Linux) or in a browser connected to RStudio Server or RStudio Server Pro (Debian/Ubuntu, RedHat/CentOS, and SUSE Linux). It includes a console, syntax-highlighting editor that supports direct code execution, as well as tools for plotting, history, debugging, and workspace management.

The largest dataset I use for my dissertation has ~1 million observations and reads in as a larger CSV (400MB, although I'm currently exploring more efficient options for reading in the data).RStudio for Mac is an integrated development environment (IDE) for R. I have been worried by what I've seen about some buggy features of RStudio on the new M1 Macs.the main packages I use are the usual for data manipulation (tidyverse etc.) plus some mapping ones (sf, leaflet, usmap). The potential costs pain me but I really just need something that will reliably work for the next year and won't require me to completely change everything I've been doing. I'm trying to decide if I should 1) pay for the repair or 2) just upgrade to a new laptop now since this one has been so glitchy and delay-ridden, and if so, if I should try hard to wait for the M1X. I am a graduate student right in the middle of my dissertation analyses in R and my laptop (2017 MacBook Pro, 8GB RAM, intel) has just gotten quoted for yet another expensive repair (argh!!).
