How to plot heatmaps using plotly in R?

Heat maps are plots that represent the data points in the form of a map, where the data points are shown with varying colors. Heat maps are widely used for visualizing complex statistical data. This recipe demonstrates an example on heatmaps in R.

Step 1 - Install the necessary package and library

install.packages("plotly") library(plotly)

Step 2 - Define a matrix

mat <- matrix(c(1:10), nrow = 4, ncol = 5, byrow = TRUE) mat

 "Matrix is :"
1	2	3	4	5
6	7	8	9	10
1	2	3	4	5
6	7	8	9	10

Step 3 - Plot a heatmap chart

Syntax for line chart using plotly - plot_ly(x, type) where, x - input data type - heatmap

figure <- plot_ly(z = mat, type = "heatmap") figure {"mode":"full","isActive":false}
