If a word conforms to a special rule, I call it an R-complete Word™.
Use the examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ R-complete }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{TAX} & \text{TRIBUTE}\\\hline \text{NEEDLE} & \text{PIN}\\\hline \text{SUN} & \text{MOON}\\\hline \text{BEST} & \text{WORST}\\\hline \text{PUZZLE} & \text{RIDDLE}\\\hline \text{COFFEE} & \text{TEA}\\\hline \text{SCIENCE} & \text{PHILOSOPHY}\\\hline \text{COLUMN} & \text{ROW}\\\hline \text{CARTOONS*} & \text{SERIES}\\\hline \text{HEAVEN} & \text{HELL}\\\hline \text{TRUCK} & \text{LORRY}\\\hline \end{array}$$ * This is a Double R-complete Word™

Hints: A hint will be given every 50 views for the first three hints. After that, 1 hint every 100 views or 15 votes.
Hint #1 (50 views):
- It is also called 3R word because it is based on a 3-component score (Bonus: "Truck" is R-Complete and "Lorry" is not)
Hint #2 (100 views):
The R-score is defined as $$R = (R_1, R_2, R_3)$$ and a word is R-complete if $$ \min(R) > 0 $$
