Dear All, I want to add a greek letter in Y-axis label of a VPC plot using xpose.VPC plotting function. I am able to do it with expression() in X-axis and main title. However, when I use it in Y-axis, it didn't work and gave me an error message "Error in ylb != "Default" : comparison is not allowed for expressions". Does anyone know how to add a greek letter in Y-axis label when using xpose.VPC function for a VPC plot?
