问题
I'm using R's psych library and I'm plotting correlation pairs on a Jupyter notebook using its pairs.panels function.
I tried using ggplot's ggsave function to save the plot but it wouldn't work. The error says:
Error in ggsave(filename = "correlation-pairs.png", : plot should be a ggplot2 plot
Is there a way to save the output of pairs.panels?
