For this we need to use its functions to calculate a clustered but unadjusted VCOV by setting type = "HC0" and cadjust = FALSE. Now that we have established that {fixest} is capable to prepare standard errors that are identical to reghdfe it is relatively straight-forward to compare the standard errors of the other packages. Here the command is generalized to allow for multiple fixed effects so you could run something like: where both $D_1$ and $D_2$ are fixed panel effects but with different dimensionality.
