P-REx Zero Console: Parameterized Runtime Execution (Z3R0 Edition) I just wanted to run one function. RStudio didn’t open. My Wi-Fi disappeared. Cookies were required — tragically, not the snacking kind. So I made this. This is P-REx Zero, a lightweight demo version of the full P-REx app. It’s a stripped-down R console for your iPhone. No cloud. No account. No add-ins. Just R, running offline, like it’s 2004 and deep focus was still fashionable. Whether you’re simulating data from the couch, calculating probabilities at 35,000 feet, or panic-testing t.test() before a meeting, P-REx Zero shows up quietly and does the math. Like a stats TA who won’t judge your p-value or your life choices. What this version does: • Runs a focused set of core R functions • Good for testing, learning, and basic stats • Offline, because life happens • Remembers your variables, even if you don’t • No ads, no feeds, no “smart” tooltips Want more? The full version of P-REx unlocks 99+ functions, extended syntax support, and extra features. But this gets you started. The paid version of P-REx Console can be found here: https://apps.apple.com/ca/app/p-rex-console/id6743998835 I built it to run one line of code. Now I use it to avoid everything else.
