Response: Yes, it will be possible to change the themes/default theme. By default, ggplot2 creates plots with a greyish background, no axes lines and white grid lines. “ggplot2” was specifically created thinking about scientific publications and user-friendliness. For this reason, its default theme is already perfect for certain scenarios. At the same time, it provides customizable options to change it. We can add an additional line to change the theme with the function theme_minimal. Here the background is white, we still do not have access lines and the gridlines are coloured in light grey. We can also choose theme_light. Here we still have a white background and light grey gridlines, however, we also have a grid box around the plot which may be useful in some cases. We can also have an option as theme_classic. It has a white background no gridlines, and tick black axis lines. Default With option as theme_minimal(): With theme_light(): With theme_classic():
