I am looking for a way to perform linear regression in R. So far I have done a lot of regression analyses, but never with repeated measures.

My dataset has the following variables:

  • DV - the dependent variable - a continuous variable
  • IV1 - first independent variable (gender) - dichotomous variable
  • IV2 - second independent variable - continuous variable
  • MEAS_POINT - dichotomous variable indicating the measurement point at which the data was collected (1 or 2)
  • S.ID - subject ID

DV and IV2 were collected at two timepoints as indicated by MEAS_POINT but IV1 (gender) was obviously measured only once.

The data is in long format.

I have no idea on how to set up a model and I don't even know if the data needs to be in long or wide format.

Also, I have no clue on how to set up an interaction term. Any help would be hugely appreciated.
