r-tips

This repository contain R-tips covering varied topics such as data wrangling, data visualization, mapping and more to help me learn R stuff.

Illustrated line plot of "How much I think I know about R" on the y-axis, and "Time" on the x-axis. Along the line are emoji-style faces, showing the non-linear progression of R knowledge over time. At first, a nervous face becomes a happy face early on in learning, then a "grimace" face at an intermediate peak before a steep decline (with an exhausted face at the local minimum). Then, a determined face charges back up a hill, reaching another peak with a "mind blown" face and text annotation "join R community on twitter" followed by another decline, but this time the faces look happy even though their "How much I think I know about R" value is declining.
