How to change the title of histograms created with pairs.panel()?

I used this function of the psych library to see the correlations of 3 samples with each other. While I could change the main title, I could not change the names of the histograms on the diagonal of the 3x3 graph. These take the names of the samples by default. How can I change the names of the histograms I'm talking about?

I did some research about it on the internet or tried to ask chatgpt but I couldn't find any information. I couldn't find anything in the documentation either. Here is my code:

pairs.panels(PartC[, c("Energy_consumption", "Energy_production", "CO2_emission")], 
             main = "The Correlation Between Energy Production, Energy Consumption, and the Amount of CO2 Emission.")

Solution

You could change the colnames of your data to the names you want to show in the plot. I use the built-in dataset iris as an example like this:

library(psych)  
data(iris)
d = iris[1:4]
colnames(d) = c("A", "B", "C", "D")
pairs.panels(d, bg=c("red","yellow","blue"),
             main="Title")
