• Have fun. Be nice. Don't spoil.
• Learn and help others learn R.
• Make R names from the sticker's six characters. Each name must be at least 3 characters long and use the blue key character. Characters can repeat.
• Any function or package name counts, from base R and about 2,100 CRAN packages.
• Click a blank in the Environment pane for hints on that word. Blue blanks are well-known words, from base R, the tidyverse, and other packages most R users have installed.
• Type or click the sticker. Enter submits, Backspace deletes, and Space shuffles.

Scoring

• A 3-character name scores 1 point. A longer name scores 1 point per character, so filter scores 6.
• A pangram uses all six characters and scores 6 bonus points, so typeof scores 12. Your first pangram earns the day's sticker for your hexwall.
• The full score earns the top rank, R Core. Each day's full score is 80% of the points from the blue well-known words, but never more than half of all the points. So you can reach R Core without knowing obscure packages.

• Points past the full score are bonus points.
• Hints never cost points. They only change your sticker's edge: silver for a pangram found before any hint, gold for every word found without hints.
