Data Analysis with R and Julia
summary
Compares hands-on R tooling (RStudio and Rattle GUI) against Julia, loading a 10,000-row Excel sample to predict marital status; a decision tree rule surfaces: homeowner & age <47.5 → single (p=0.75). Notes R is memory-bound (usable ≈ RAM/4) and limited by 2^31-1 object size; demos run trees, SVM and neural nets. Benchmarks show Julia far faster on fib, parse-int, quicksort and pi-sum (R times in the hundreds vs Julia near C speed), explained by Julia ~C-speed via LLVM JIT and multiple dispatch. Recommends R for production, Julia for personal investment.
