It handles numerics, characters, factors, and logicals.

Compare Two Dataframes and Return Adds, Changes, and Deletes
Compares two dataframes with a common key
and returns the delta records. The package will return
three dataframes that contain the added, changed,
and deleted records.

An implementation of multivariate linear process bootstrap (MLPB) method and sliding window technique to assess the dynamic functional connectivity (dFC) estimate by providing its confidence bands, based on Maria Kudela (2017) <doi: 10.1016/j.neuroimage.2017.01.056>.
It also integrates features to visualize non-zero coverage for selected a-priori regions of interest estimated by the dynamic functional connectivity model (dFCM) and dynamic functional connectivity (dFC) curves for reward-related a-priori regions of interest where the activation-based analysis reported.

Computes small-sample degrees of freedom adjustment for
heteroskedasticity robust standard errors, and for clustered standard errors
in linear regression. See Imbens and Kolesár (1994)
<doi:10.1162/REST_a_00552> for a discussion of these adjustments.
