Hi there,

I am trying to run a regression discontinuity based upon the dataset found below. However I keep running into the error c() should be set within the range of year.
How can I redefine c() so that it does not hold the default value of 0.

My cutoff is defined as 1872, the year when the treatment dummy variable takes the value 1.

The error shows up when I attempt

rdplot hiscam year

Best Wishes,
James
