In qtlcharts: Interactive Graphics for QTL Experiments

Interactive heat map

Description

Creates an interactive heatmap, with each cell linked to plots of horizontal and vertical slices

Usage

iheatmap(z, x = NULL, y = NULL, chartOpts = NULL, digits = 5)

Arguments

z	Numeric matrix of dim length(x) x length(y)
x	Vector of numeric values for the x-axis
y	Vector of numeric values for the y-axis
chartOpts	A list of options for configuring the chart (see the coffeescript code). Each element must be named using the corresponding option.
digits	Round data to this number of significant digits before passing to the chart function. (Use NULL to not round.)

Details

By default, the z-axis limits are from -max(abs(z)) to max(abs(z)), and negative cells are colored blue to white which positive cells are colored white to red.

Value

An object of class htmlwidget that will intelligently print itself into HTML in a variety of contexts including the R console, within R Markdown documents, and within Shiny output bindings.

Examples

n <- 101
x <- y <- seq(-2, 2, len=n)
z <- matrix(ncol=n, nrow=n)
for(i in seq(along=x))
    for(j in seq(along=y))
        z[i,j] <- x[i]*y[j]*exp(-x[i]^2 - y[j]^2)
