Create a heat map in ggplot2 using the geom_tile function. Add the values on the cells, change the color palette and customize the legend color bar

geom_rect() and geom_tile() do the same thing, but are parameterised differently: geom_tile() uses the center of the tile and its size (x, y, width, height), while geom_rect() can use those or …

This is the most basic heatmap you can build with R and ggplot2, using the geom_tile() function. Input data must be a long format where each row provides an observation.
