paired {arsenal} | R Documentation |
Summarize one or more variables (x) by a paired time variable (y). Variables on the right side of the formula, i.e. independent variables, are summarized by the two time points on the left of the formula. Optionally, an appropriate test is performed to test the distribution of the independent variables across the time points.
paired( formula, data, id, na.action, subset = NULL, strata, control = NULL, ... )
formula |
an object of class |
data |
an optional data frame, list or environment (or object coercible by |
id |
The vector giving IDs to match up data for the same subject across two timepoints. |
na.action |
a function which indicates what should happen when the data contain |
subset |
an optional vector specifying a subset of observations (rows of data) to be used in the results. Works as vector of logicals or an index. |
strata |

additional arguments to be passed to internal |
Do note that this function piggybacks off of tableby
quite heavily, so there is no
summary.paired
function (for instance).
