Adding a greek letter in Y-axis label using xpose.VPC

From: [email protected] [mailto:[email protected]] On Behalf Of Yulan Qi Sent: Thursday, September 18, 2014 12:54 PM To: [email protected] Subject: [NMusers] Adding a greek letter in Y-axis label using xpose.VPC 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?

To get around this problem before the next release of xpose on CRAN you can use the following code: # create your VPC and save the results as a variable vpc_plots <- xpose.VPC() # update the y-axis label of any plot in the list of plots created using the xpose.VPC command # Here I update the label for the first plot vpc_plots@plotList[[1]] <- update(vpc_plots@plotList[[1]],ylab=expression(hat(beta))) Hope this helps.
