Visualization of correlation using heatmap.
This session demonstrates how to plot to visualize the correlation between variables using ggplot2. Other correlation visualizations are not suitable when the number of observations being plotted is very large. Overlap prevents the display of correlation. Heatmap is very effective method to overcome this problem.
Heatmap visualise the magnitude of values using proportional intensities and hues of colors.
The following code is used in the tutorial.

Nice representation of bulk data.
May be people will update their knowledge on R program Instead of using routine data analysis tools in Excel/Origin.
Congratulations.
