plotCluster(res = res_clusterItems,
                   showLegend = FALSE,
                   tickWidth = 0.2)

Arguments

res

Results generated by clusterItems or testMI.

showLegend

Adds item identifiers to the plot. Defaults to FALSE.

tickWidth

Give widths of ticks manually. Defaults to 0.2.

Value

A plot, either a single plot if MI analysis was done for only one parameter, or multiple plots showing the subsequent clustering via item loadings and difficulties. Relative DIF effects are always moved to a scale where the lowest DIF values is zero.
