  1. bugfix in tidy.lm

    jrnold committed Mar 18, 2017
    If the regression is rank deficient and `confint = TRUE`, then `tidy()` will throw an unhelpful error like,
    ```
    Error in data.frame(..., check.names = FALSE) :
      arguments imply differing number of rows: 199, 535
    Calls: <Anonymous> ... tidy.lm -> process_lm -> cbind -> cbind -> data.frame
    ```
    
    This fixes this by dropping the dropped coefficient from the confidence intervals prior to binding them to the results. The approach used in this patch is the same one that appears in `summary.lm` to handle dropped coefficients.
