In the labels argument you can specify the labels you want for each point.

Moreover, you can use the identify function to manually label some data points of the plot, for example, some outliers. Plot(y ~ x, pch = 19, col = "black") # Equivalent In order to plot the observations you can type: plot(x, y, pch = 19, col = "black") You can review how to customize all the available arguments in our tutorial about creating plots in R.Ĭonsider the model \(Y = 2 + 3X^2 + \varepsilon\), being \(Y\) the dependent variable, \(X\) the independent variable and \(\varepsilon\) an error term, such that \(X \sim U(0, 1)\) and \(\varepsilon \sim N(0, 0.25)\). You can also specify the character symbol of the data points or even the color among other graphical parameters. Passing these parameters, the plot function will create a scatter diagram by default.

You can create scatter plot in R with the plot function, specifying the \(x\) values in the first argument and the \(y\) values in the second, being \(x\) and \(y\) numeric vectors of the same length. The main use of a scatter plot in R is to visually check if there exist some relation between numeric variables. Plt.Scatter plots are dispersion graphs built to represent the data points of variables (generally two, but can also be three).
