Introduction to Customizing Plots

Customizing plots in R helps make data visualizations more effective and visually appealing.

Changing Colors

You can modify colors in plots using the col parameter.

plot(1:10, col='blue', pch=16, main='Colored Points')

Adding Titles and Labels

You can add a title, x-axis, and y-axis labels to a plot.

plot(1:10, main='Customized Plot', xlab='X Axis', ylab='Y Axis')

Modifying Point Shapes

You can change the shape of points using the pch parameter.

plot(1:10, pch=17, col='red', main='Triangle Shaped Points')

Adjusting Line Styles

You can change line types using the lty parameter.

plot(1:10, type='l', lty=2, col='blue', main='Dashed Line Plot')

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)

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')

Saving Customized Plots

You can save your customized plots using pdf() or png().

png('custom_plot.png')
plot(1:10, col='green')
dev.off()
