density-methods: Density plot of a ExpressionSet object In lumi: BeadArray Specific Methods for Illumina Methylation and Expression Microarrays

Description

Creating density plot of sample intensities in a ExpressionSet object. It is equivalent to hist-methods.

Usage

 ```1 2 3 4``` ```## S4 method for signature 'ExpressionSet' density(x, logMode=TRUE, xlab = NULL, ylab = "density", type = "l", col=1:dim(x)[2], lty=1:dim(x)[2], lwd=1, xlim = NULL, index.highlight = NULL, color.highlight = 2, symmetry = NULL, addLegend = TRUE, legendPos="topright", subset = NULL, main="", ...) ```

Arguments

 `x` a `ExpressionSet` object `logMode` determine whether the density plot is based on a log2 scale `xlab` xlab of the density plot `ylab` ylab of the density plot `type` parameter of plot function `col` line colors of the density plot `lty` line types of the density plot `lwd` line width of plot function `xlim` parameter of the plot function `index.highlight` the column index of the highlighted density curve `color.highlight` color of highlighted density curve `symmetry` the boundary position suppose to be symmetric distributed `addLegend` whether add legend to the plot or not `legendPos` the legend position. It can be a string specifying the position, or a length two vector specifying the x and y position. Please check `legend` for more details. `subset` subset of rows used to plot. It can be an index vector, or the length of a random subset `main` title for the plot `...` additional parameters for `density` function
