The Quantile-Quantile Plot or (Q-Q Plot) is defined as a value of two variables that are plotted corresponding to each other and check whether the distributions of two variables are similar or not with respect to the locations.
qqline() function in R Language is used to draw a Q-Q Line Plot.
Syntax: qqline(x, y, col)
x, y: X and Y coordinates of plot
col: It defines color
Returns: A QQ Line plot of the coordinates provided
Example 1: Implementation of Basic QQplot Interpretation
Above is a representation of QQplot of Normally Distributed Random Numbers.
Example 2: Implementation of QQplot of Logistically Distributed Values
Above is the Q-Q Plot of theoretical quantiles.
