I'm having a bit of trouble plotting the regression line of
multivariable linear model.
Specifically my model has one response and two predictors, i.e. it's of
the form
Y = b_0+b_1*X_1+b_2*X_2
Plotting the regression line for a single predictor model
Y = b_0+b_1*X_1
is simple enough, just call abline() with the coefficients returned by
lm().
However, I don't know if this can be adapted to multivariable linear
models.
I also know about curve(), but I don't know how am I supposed to input
the multivariable model's coefficients into it.
