Trying to do a reset test in Rstudio

I'm trying to do a reset test in Rstudio. Im new to this. This is my code:

model1 <- lm(inntekt ~ arbeidstid + kvinne + alder + leder + utd_hoy, data = d) summary(model1)

install.packages("lmtest") library("lmtest")

resettest(lm, power = 2:3, type = "regressor", data = d)

When i am trying to run the test i get this:

resettest(lm, power = 2:3, type = "regressor", data = d) Error: object of type 'closure' is not subsettable

Can somebody pleas help me? I am happy for all answers :)
