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 ...
