Re: [R] dplyr summarize by groups

This is because options(digits=3) specifies the number of significant digits, not the number of decimal places. See ?options and search for digits. > a <- 12.345 > options(digits=4) > print(a) [1] 12.35 > options(digits=5) > print(a) [1] 12.345 > options(digits=2) > print(a) [1] 12 > On Sat, Nov

[R] dplyr summarize by groups
