Decomposing leaf mass into metabolic and structural components explains divergent patterns of trait variation within and among plant species - Oecologia
Across the global flora, interspecific variation in photosynthetic and metabolic rates depends more strongly on leaf area than leaf mass. In contrast, intraspecific variation in these rates is strongl...

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....
genzplyr is dplyr, but bussin fr fr no cap.

Rにまつわる怖い話をいくつか書いてみました。lmerのデフォルト設定がREML=TRUEとなっており、モデル選択できない使用になっているのに気づかず、やらかしてしまっている論文はかなり多いのでは、、と思ってます。

モデル選択できないGLMM 複数マッチのエラーがでない “sample” surprise なんとなく使っていると痛い目にあうRのデフォルト設定。
モデル選択できないGLMM GLMMで解析する際、lme4::lmer()（あるいはlme4::glmer()）を使うことは多い。しかし、これらの関数はデフォルト設定ではモデル選択できない。なぜなら、デフォルトでREML = TRUE（制限付き最尤...

🌳 How long do trees really live?
Our new study in Nature Ecology & Evolution reveals that Japanese trees can have a potential lifespan of ~400 years, but most live only ~80 years. Huge congrats to first author Yuta Kobayashi for this fascinating work! 🎉
