plot(1:10, type='l', lty=2, col='blue', main='Dashed Line Plot')6
Adding a Legend
Legends help explain different elements in a plot.
plot(1:10, col='blue', pch=16)
legend('topright', legend='Data Points', col='blue', pch=16)7
Customizing Axes
You can manually set axis limits and labels using xlim and ylim.
plot(1:10, xlim=c(0,15), ylim=c(0,20), main='Custom Axes')8
