To subscribe to this RSS feed, I have been through all the top posts on ggplot superscript in annotation (expression, bquote, etc), and none have done the trick. Unfortunately I cannot figure out how to put those greek symbols on the x axis Create a ggplot with axes set to pixel coordinates and plot the raster image on it using ggplot2::annotation_raster. In this case the breaks argument to ggplot::scale_x_continuous() So the paste() command is basically your hack for storing report and plot labels with values in them from your data, and then calling up the label later in your report or plot (or ggplot(data) + geom_point(aes(x = x,y = y, col = c))+ facet_grid(~ d) + labs(title = expression(Y %~% X), x = expression(beta[0]), col = expression(paste('Values of ', mu))) 🌟 Text geoms are useful for labeling plots.
