R: How do I replace a column with another column from a different dataframe?

Question

I want to replace the 6th column of the ped dataframe with the Phenotype column from bipolar_ctl dataframe.

My attempt:

dplyr::mutate_at(ped, vars(-one_of("bipolar_ctl$Phenotype")))

Answer 1

Using base R,

ped[,6] = bipolar_ctl$Phenotype
