The R package wrapr 1.5.0 is now available on CRAN. wrapr includes a lot of tools for writing better R code: I’ll be writing articles on a number of the new capabilities. For now I just leave you with the nifty operator coalesce notation. Coalesce takes values from its arguments in left to right order taking the first non-NA value (if any available): NA %?% 5 # [1] 5 1 %?% 5 # [1] 1 5 %?% NA # [1] 5 For vectors each position is calculated independently, and scalars are re-cycled to vector sizes. This allows fairly complicated coalesce strategies (such as take from first two vectors if possible, else write in zero) to be expressed very succinctly: vec1 <- c(1, 2, NA, NA) vec2 <- c(10, NA, 20, NA) vec1 %?% vec2 %?% 0 # [1] 1 2…
