plotHeatmap function

Plot heatmap.

Given a matrix or list of matrizes x this function visualizes each matrix with a heatmap.

plotHeatmap(x, value.name = "Value", show.values = FALSE)

Arguments

• x: [matrix | list[matrix]]

  Either a matrix or a list of matrizes.

• value.name: [character(1)]

  Name for the values represented by the matrix. Internally, the matrix is transformed into a data.frame

  via melt in order to obtain a format which may be processed by ggplot easily. Default is Value .

• show.values: [logical(1L)]

  Should the values be printed within the heatmap cells? Default is FALSE.

Returns

[ggplot] ggplot object.

Examples

# simulate two (correlation) matrizes
x = matrix(runif(100), ncol = 10)
y = matrix(runif(100), ncol = 10)
## Not run:

pl = plotHeatmap(x)
pl = plotHeatmap(list(x, y), value.name = "Correlation")
pl = plotHeatmap(list(MatrixX = x, MatrixY = y), value.name = "Correlation")
## End(Not run)
