In this R tutorial we will learn how to make scatterplot in R to examine the relationship between two numeric variables. We will also learn to calculate pearson's correlation for our data and modify the scatterplot using R programming language. In this tutorial we will use the "plot", "cor", "abline", "spline," "lty" and "lines" functions in R programming language.
