Replace values

R:

mtcars %>% mutate(cyl = replace(cyl, 4, 400))

pandas:

mtcars.assign(cyl=mtcars.cyl.replace(4, 400))

plydata:

mtcars >> dp.define(cyl='cyl.replace(4,400)') (mutate ok)

dpylython:

dp.DplyFrame(mtcars) >> dp.mutate(cyl=X.cyl.replace(4, 400))

dfply:

mtcars >>dp.mutate(cyl = X.cyl.replace(4, 400))

dppd:

dp(mtcars).mutate(cyl = X.cyl.replace(4 ,400))
