Alternatively, the function panel changes a data.frame into a panel from which the functions l and f (creating leads and lags) can be called. Otherwise you can set the panel 'live' during the estimation using the argument panel.id (see for example in the function feols).

Examples

data(base_did)

# Setting a data set as a panel
pdat = panel(base_did, ~id+period)

# ... allows you to use leads and lags in estimations
feols(y~l(x1, 0:1), pdat)

# Now unpanel => returns the initial data set
class(pdat) ; dim(pdat)
new_base = unpanel(pdat)
class(new_base) ; dim(new_base)
