I want to extra the part of the formula not including the response variable from an lm object. For example if the lm object ABx.lm was created by the call
ABx.lm <- lm( y ~ A + B + x, ...) Then ACx.lm is saved as part of a workspace. I wish to extract "~ A + B + x". Later in my code I will fit another linear model of the form z ~ A + B + x for some other response variable z. I would be grateful for any suggestions of a nice way to do this.
