Hot 3 Way. I'm trying to code a three-way frequency table in R, but I'm stumbling due to the third variable. I thought only one should be hot???
It's important to recognize that a light switch is designed to interrupt the "hot" wire when it's turned off. Three-way switches allow for controlling a light fixture from two separate locations, these are usually used at the top and bottom of a flight of stairs or at two different entrances to a room. For instance. by(data = my.data, INDICES = my.data$City.

One way to achieve this would be to use by(). It's important to recognize that a light switch is designed to interrupt the "hot" wire when it's turned off. For instance. by(data = my.data, INDICES = my.data$City.
