Webb12 feb. 2016 · 3 Answers Sorted by: 7 A workaround would be f <- function (data, x) { v <- substitute (x) data %>% eval (expr = v, envir = .) %>% mean () } The problem is that the pipe functions ( %>%) are creating another level of closure which interferes with the evaluation of substitute (x). You can see the difference with this example WebbWe could use the math formula: s u m ( x 1 − x 2) 2. In the nested manner this would be: x1 <- 1:5; x2 <- 2:6 sqrt (sum ( (x1-x2)^2)) However, if we chain this we can see how we would perform this mathematically. # chaining method (x1-x2)^2 %>% sum () %>% sqrt () If we did it by hand we would perform elementwise subtraction of x2 from x1 then ...

WebbThe operators pipe their left-hand side values forward into expressions that appear on the right-hand side, i.e. one can replace f (x) with x %>% f (), where %>% is the (main) pipe-operator. When coupling several function calls with the pipe-operator, the benefit will become more apparent. Consider this pseudo example:
