P-REx Zero Console

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

The full version of P-REx unlocks 99+ functions, extended syntax support, and extra features. But this gets you started.

I built it to run one line of code.
Now I use it to avoid everything else.
