massi_cluster_plot: massi_cluster_plot

In massiR: massiR: MicroArray Sample Sex Identifier

Description

This function produces three figures in a new graphics device to enable the exploration of the massi_cluster and massi_select results.

Usage

massi_cluster_plot(massi_select_data, massi_cluster_data)

Arguments

massi_select_data	A data.frame containing the subset of y chromosome probe values for each sample. This is returned when running the massi_select function.
massi_cluster_data	This is the list returned from the massi_cluster function.

Details

The first figure is a heatmap depicting probe values for each sample. The second figure is a bar plot showing the mean probe expression and standard deviation for each sample. The bars are colored with respect to the predicted sex. The third figure is a principal component plot which represents the distances bewteen samples, with each cluster highlighted with elipses.

Value

Returns three plots in a new graphics device.

Examples

# load the test dataset
data(massi.test.dataset, massi.test.probes)

# select the y chromosome probes using massi_select
massi_select_out <- 
massi_select(massi.test.dataset, massi.test.probes)

# cluster samples to predict sex using massi_cluster
massi_cluster_out <- 
massi_cluster(massi_select_out)

# produce plots using massi_cluster_plot
massi_cluster_plot(massi_select_out, massi_cluster_out)
