olsrr 0.60 - olsrr::ols_step_all_possible function displays the incorrect values under "Mallow's Cp"

[LSantanaZA]

Hi,

I encountered an issue with the standard output of "olsrr::ols_step_all_possible" in version 0.6.0.

The last column is labelled "Mallow's Cp" but appears to actually print the values for the predicted R-square.

This can be seen using the example code provided by the function's help file:

model <- lm(mpg ~ disp + hp, data = mtcars)
k <- ols_step_all_possible(model)

# output created by default (note the values of Mallow's Cp)
k
#  Index N Predictors  R-Square Adj. R-Square Mallow's Cp
#1     1 1       disp 0.7183433     0.7089548   0.6751205
#2     2 1         hp 0.6024373     0.5891853   0.5096958
#3     3 2    disp hp 0.7482402     0.7308774   0.6945438
