Hi,
Suppose I want to create a new variable heart_disease with two levels (0 and 1) from three existing binary variables (heart_failure, angina, MI). The variable heart_disease will be coded as 1 if any of the existing variables have value of 1; else heart_disease = 0. How do I code this? Please see the dataset blurb below.
Thank you so much!

0 | 0 | 0 | 0 |
1 | 1 | 0 | 1 |
1 | 0 | 1 | 1 |
