Arguments

data	numeric: either the data matrix only, or the data matrix plus the vector of group membership.
item	factor: the vector of group membership
grp	numeric or character: either the number or the name of the single item for which the plots of conditional expected scores are plotted
focal.name	numeric or character: a single value
ref.name	numeric or character: a single value
anchor	numeric: a vector of integer values specifying which items are currently considered as anchor (DIF free) items.
