Description

Heatmap and clustering of deltadeltaCt values from different sample comparisons using qPCR data.

Usage

1
heatmapSig(qDE, comparison = "all", col, zero.center = TRUE, mar, dist = "pearson", ...)

Arguments

qDE

data.frame or list, as created by ttestCtData or limmaCtData.

comparison

integers or the names of the comparisons to include in the plot. Defaults to all results in the qDE data, but a minimum of two is required.

col

colour scheme to use for the plot.

zero.center

logical, should the colour scale be centered around 0.

mar

vector of length two, the bottom and right side margins mof the heatmap.

dist

character string, either "pearson" (default) or "euclidean" indicating what type of distance is used for the clustering.

...

further arguments passed to heatmap.2.

Details

This function can be useful if multiple conditions are compared, for detecting features with similar behaviour in comparisons, and look at the general level of up and down regulation.

Value

A plot if produced in the current graphics device.
