Description

Plot a single probe, aka feature from an ExpressionSet object, optionally highlighting certain samples, and adding a mean expression line.

Usage

  plot_ExpressionSet(x, feature = 1, xlab = "Rank",
    ylab = "Expression Level (log2)",
    main = featureNames(x)[feature], add.mean = TRUE,
    sort = TRUE, samples = NULL)

Arguments
