creating a categorical variable

[OUI]

hello, I'm trying to create a new categorical variable based on percentiles higher than 25 but lower than 50 but dont know ho to express that in the line of code, here is the one I have so far.

income.type <- case_when(dataset$income == .25~ 1,
dataset$income >= .25 but <= .75 ~ 2,
dataset$income>= .50 but <= .75 ~ 3,
dataset$income == .75~ 4=)

You can use the AND operator, &, to express the logic.

income.type <- case_when(dataset$income <= .25~ 1,
dataset$income > .25 & dataset$income <= .5 ~ 2,
dataset$income> .50 & dataset$income <= .75 ~ 3,
dataset$income > .75~ 4=)

Notice that I changed the comparisons. You should not have a condition for == 0.25 and another one that starts with >= 0.25. Those will both be TRUE for values of 0.25. I merely guessed at a possible arrangement of the logic and you should change that to whatever is correct for your situation.
