How to update values with dplyr

dplyr, r

Solution

Use `mutate` and `ifelse`

library(dplyr)

mutate(net4,
  ave = ifelse(ave < 10 & ave != temp2, temps2 / NNET * NET, ave)
)

Problem

I'm currently trying to update values from a data.frame using dplyr but I don't know if it is possible to replace a subset of values? ``` net4 <- read.table(text=" temps2 NNET NET ave 1 18 2 4 36 2 18 2 4 36 3 22 2 4 44 4 18 2 4 36 5 22 2 4 44 6 27 3 4 36", header=TRUE) # I would like to do the same command line as below: subs <- (net4$ave < 10 & net4$ave!=net4$temps2) net4$ave[subs] <- with(net4[subs,], temps2/NNET*NET) ``` Thanks
