nuseplot-methods: Box Plots of Normalized Unscaled Standard Errors (NUSE)

Description Arguments Details Author(s) See Also Examples

Description

Produce boxplot of Normalized Unscaled Standard Errors (NUSE) for the set of arrays.

Usage

nuseplot(x, which = "UnitName", size = 0, range = 0, names = "namepart", main = "NUSE Plot", ylim = c(0.8, 1.2), las = 2, add.line = TRUE, outline = FALSE, ...)

Arguments

x

object of class or QualTreeSet.

which

type of probes to be used, for details see validData (only ExprTreeSet).

size

length of sequence to be generated as subset (only ExprTreeSet).

range

determines how far the plot whiskers extend out from the box.

names

optional vector of sample names.

main

the main title for the plot.

ylim

range for the plotted y values.

las

the style of axis labels.

add.line

logical, if TRUE a horizontal line is drawn.

outline

if outline is not true, the outliers are not drawn (only ExprTreeSet).

...

optional arguments to be passed to boxplot.

Details

Create boxplots of Normalized Unscaled Standard Errors (NUSE) for the set of arrays.

For names=NULL full column names of slot data will be displayed while for names="namepart" column names will be displayed without name extension. If names is a vector of column names, only these columns will displayed as boxplot.

If an object of class QualTreeSet was created by fitting a probe level model with qualopt="all" then nuseplot will plot NUSE for "all" quality options. If you want to plot NUSE for a certain quality option only, e.g. "normalized" data only, then you can use parameter names with names="namepart:<qualopt>", e.g. names="namepart:normalized".
