error while running RDestimate

Hi,
i am trying to run a
Regression Discontinuity using RDestimate(formula = y ~x, data = df).
df looks like below:

<dbl>              Y      X.      <lgl>     <lgl>     

1 1946 0 0.0615 TRUE TRUE
2 1946 0 -0.0615 FALSE TRUE
3 1948 1 0.105 TRUE TRUE
4 1948 0 -0.105 FALSE TRUE
5 1948 0 -0.536 FALSE FALSE
6 1950 0 0.164 TRUE TRUE

I a getting the below error :
Error in X[subset] : invalid subscript type 'list'.

Any idea what is wrong?
