问题 I am having trouble adding R2 annotations to a faceted plot, where my R2 values are sometimes <0.01 (yes, it's not a good regression). I would like the 2 of R2 to be superscript. I have tried several options but seem to be stymied by the < symbol in my values eg, using the iris data set, I first set up a new data frame with my R2 values previously calculated. The x & y positions are also set up as these are different for every facet (not essential for the iris dataset, but it is for mine)

问题 I'm trying to edit the labels in the legend so that the first label (WT) is in plain text, whilst the subsequent 7 are in italics. I have been using element_text(face=c("plain", rep("italic",7))) , but this has resulted in none of the labels being converted to italics. I'm a bit confused why it hasn't worked because element_text(face="italic") converts all the labels into italics. My plot is as follows: library(tidyverse) for_plot <- read_csv(file = "Row, Time, Mutant, Mean 1, 1, ppi1, 0.8008
