I am trying to see how word frequency correlates with phonotactic probability using R, but there are a few issues. First, and most generally, I don't know merge these two graphs together (i want them to appear on the same axis).
This leads to a second problem because the first graph's y values are in probabilities, and the second is a count, so the scales are not the same. Should I combine data frames first, or is there a simpler way to merge two graphs?
Here is the reproducible sample, and the code for my graphs:
Phonotactic_Probability <-structure(list(Word = c("Baby", "Bagel", "Bandage", "Banjo",
"Carriage", "Carrot", "Chicken", "Chipmunk", "City", "Cobra",

Thanks in advance.
CodePudding user response：
One way could be to use a second y axis. Although this method is to be used critically, in this situation I think it is appropriate:
library(tidyverse)
df <- left_join(Phonotactic_Probability, Word_Frequency, by="Word")
coeff <- 100000
ggplot(df, aes(x = reorder(Word,`Biphone Probability`)))
geom_point(aes(y = `Biphone Probability`), size = 4, color = "red")
geom_point(aes(y = Freq10k / coeff), shape=23, fill="blue", size=4)
scale_y_continuous(
name = "Biphone Probability",
sec.axis = sec_axis(~.*coeff, name = "Word frequency per 10k")
)
xlab("\nTarget word")
theme_bw(14)
theme(
axis.title.y = element_text(color = "red", size=13, face="bold"),
axis.title.y.right = element_text(color = "blue", size=13, face="bold"),
axis.text.x = element_text(angle = 45, vjust = 0.5, hjust=1)
)
ggtitle("Biphone Probability and Word frequency per 10k")
