Format aesthetics for the supplementary (new) biplot samples

Description

This function allows formatting changes to new samples.

Usage

newsamples (bp,  col = "darkorange1", pch = 1, cex = 1, label = FALSE,
label.name = NULL, label.col = NULL,label.cex = 0.75, label.side = "bottom", 
label.offset = 0.5, connected = FALSE, connect.col = "black", connect.lty=1, 
connect.lwd=1)

Arguments

`bp`	an object of class `biplot`.
`col`	the colour(s) for the new samples, with default `darkorange1`.
`pch`	the plotting character(s) for the new samples, with default `1`.
`cex`	the character expansion(s) for the new samples, with default `1`.
`label`	a logical value indicating whether new samples should be labelled or not, with default `FALSE`.
`label.name`	the label names for the new samples.
`label.col`	a vector of the same length as the number of new samples containing the colour(s) for the labels of the new samples, with default the colour of the sample points.
`label.cex`	the label text expansion(s) for the new samples, with default `0.75`.
`label.side`	the side at which the label of the plotted point appears, with default `bottom`. Note that unlike the argument `pos` in `text()`, options are "`bottom`", "`left`", "`top`","`right`" and not `1`, `2`, `3`, `4`.
`label.offset`	the offset of the label from the plotted point. See `?text` for a detailed explanation of the argument `offset`.
`connected`	a logical value indicating whether samples are connected in order of rows of the data matrix, with default `FALSE`.
`connect.col`	the colour of the connecting line, with default `black`.
`connect.lty`	the line type of the connecting line, with default `1`.
`connect.lwd`	the line width of the connecting line, with default `1`.

Value

The object of class biplot will be appended with a list called newsamples containing the following elements:

`col`	the colour(s) of the new samples.
`pch`	the plotting character(s) of the new samples.
`cex`	the character expansion(s) of the plotting character(s) of the new samples.
`label`	a logical value indicating whether new samples are labelled.
`label.col`	the label colours of the new samples.
`label.cex`	the label text expansions of the new samples.
`label.side`	the side at which the label of the plotted point appears.
`label.offset`	the offset of the label from the plotted point.
`connected`	a logical value indicating whether new samples are connected.
`connect.col`	the colour of the connecting line.
`connect.lty`	the line type of the connecting line.
`connect.lwd`	the line width of the connecting line.

Examples

biplot(data = iris[1:145,]) |> PCA() |> samples(col = "grey") |>
interpolate(newdata = iris[146:150,]) |> newsamples(col = rainbow(6), pch=15) |> plot()
