Let’s start visualizing correlation values in a plot.Open your RStudio and begin typing in !!!
Let's import the library corrplot for correlation matrix visualization
Let's store the dataset mtcars into dataframe named DataFrame
DataFrame <- mtcars
Let's find the correlation matrix of this data set
corrMatrix <- cor(DataFrame)
Let'c visualize the correlation matrix.This plot will tell about the correlation between the feature variables in the data set.
Dark red means correlation=-1
Dark blue means correlation=1
White means correlation=0
If you want to see the exact correlation value in the plot .Then run the following code
