Internal functions for qqplot of package distrMod

Description

These functions are used internally by qqplot of package distrMod.

Usage

.labelprep(x,y,lab.pts,col.lbs,cex.lbs,adj.lbs,which.lbs,
           which.Order,order.traf, which.nonlbs)

Arguments

`x`	a (numeric) vector
`y`	a (numeric) vector of same length as `x`
`cex.lbs`	magnification factor for the plotted observation labels
`col.lbs`	color for the plotted observation labels
`adj.lbs`	adjustment factor for the plotted observation labels
`lab.pts`	character or `NULL`; observation labels to be used
`which.lbs`	integer or `NULL`; which observations shall be labelled
`which.Order`	integer or `NULL`; which of the ordered (remaining) observations shall be labelled
`order.traf`	function or `NULL`; an optional trafo by which the observations are ordered (as order(trafo(obs)).
`which.nonlbs`	indices of the observations which should be plotted but not labelled; either an integer vector with the indices of the observations to be plotted into graph or `NULL` — then all non-labelled observations are plotted.

Details

.labelprep prepares the labels for later output: first some indices among x according to which.lbs are (optionally) selected, then orders both x and y according to the order of the remaining (optionally transformed by order.traf) values of x (decreasing); finally only the order statistics (w.r.t. the preceding ordering) as specified in which.Order are returned; correspondingly, labels, colors, and magnification factors, are ordered respectively thinned out.

Value

.labelprep

a list with components x0 (the thinned out and ordered vector x), y0 (the thinned out and ordered vector y), lab (the thinned out and ordered vector of labels lab.pts), col (the thinned out and ordered vector of colors col.lbs), cex (the thinned out and ordered vector of magnification factors cex.lbs), ord (the (ordered according to y) indices of the observations selected for labelling), ns (the (ordered) indices of the selected non-labelled observations).
