makeCrossCorDyadic | R Documentation |
Calculates cross-correlations for a variable that is nested by person within dyad (e.g. it is the same variable for both partners). It returns a dataframe with either: 1) if "time_lag" is null, the largest absolute cross-correlation and its lag added for each dyad (e.g., it returns either the most negative or most positive cross-correlation, whichever is larger in absolute terms – the sign is retained), or 2) if "time_lag is specified, the cross-correlations for each dyad at that lag.
makeCrossCorDyadic( basedata, dyadId, personId, obs_name, dist_name, time_lag = NULL, lagMax = NULL )
basedata |
The original dataframe provided by the user that includes all variables needed for an rties analysis, including potential system and control variables, etc. |
dyadId |
The name of the column in the dataframe that has the couple-level identifier. |
personId |
The name of the column in the dataframe that has the person-level identifier. |
obs_name |
The name of the column in the dataframe that has the time-varying observable (e.g., the variable for which dynamics will be assessed). |
dist_name |
The name of the column in the dataframe that has a variable that distinguishes the partners (e.g., sex, mother/daughter, etc) that is numeric and scored 0/1. |
time_lag |
If null (the default), the maximum absolute value cross-correlation and its corresponding lag are returned. Otherwise, the cross-correlation at the specified time lag is returned. |
lagMax |
Maximum lag at which to calculate the acf if time_lag is null. Default is 10*log10(N/m) where N is the number of observations and m the number of series. |
A cross-sectional version of the original dataframe with maximal absolute-value cross-correlations and their lags added for each dyad.
