How to get Euler–Mascheroni's constant in R? -


is euler–mascheroni's constant $\gamma \approx 0.577$ available in r, $\pi$ pi or $e$ exp(1)?

mathmatically can write constant of interest negative of derivative of gamma function evaluated @ 1. r has derivative of gamma function digamma it's matter of plugging in.

-digamma(1) #[1] 0.5772157
