Visualization of correlation matrix in R | ggcorrplot tutorial | ggplot2 extension | R Tutorial

In this video, we will take a quick look at the 'ggcorrplot' package and see how to use it and visualize a correlation matrix.

mtcars dataset used for demonstration purpose.

Items covered :
- Visualize correlation matrix (square and circle methods)
- hc-order method
- formatting correlation coefficient labels on the plot (changing color and size)
- Adding ggplot themes
- changing legend colors
- Layout types - lower & upper
- Reflecting & dropping insignificant coefficients basis comparision of p-values and significance levels

Thank you, very clear and informative.

Thank you for the nice presentation, I would like to put p values as Asterix in the correlogram instead of crosses or white ?

Thanks for the explanation! I don't understand what is the meaning of the size of the circle? Do they have the same meaning as the color scale? Because I see very small red circle which would mean that the size and the colors are not matching.

well explanation, thanks for uploading

for correlation plot are all variables required to be numeric..

Thanks this helped me a lot with my assignment

Most excellent tutorial! Can you show please how to create a Geom Smooth plot with double (supplementary) Y axis? Also, non linear regression would be great! Thanks in advance amigo!! ❤️🇲🇽❤️

how can we combine two plots in a single ? suppose I have correlation matrix for cases and controls, now I want to make a single plot showing its upper part for cases and lower for controls or vice versa

Is it possible to change to spearman correlation?
