Create a log-log plot without log scale ticks:.

Key function: annotation_logticks() Data: Animals data sets, from the package MASS Note that, log scale ticks make sense only for log scale base 10.

Show exponent after the logarithmic changes by formatting axis ticks mark labels.

Log transform x and y axes into log2 or log10 scale.

In this R graphics tutorial, you will learn how to: coord_trans() is different to scale transformations in that it occurs after statistical transformation and will affect only the visual appearance of geoms. If you fit anything to the data it would probably change the fitted values.Īn alternative is to use the function coord_trans() for transformed Cartesian coordinate system. Note that, the scale functions transform the data. An other possibility is the function scale_x_log10() and scale_y_log10(), which transform, respectively, the x and y axis scales into a log scale: base 10. This can be done easily using the ggplot2 functions scale_x_continuous() and scale_y_continuous(), which make it possible to set log2 or log10 axis scale.

This article describes how to create a ggplot with a log scale.
