Hi,

I've used the following code to create an ERP wave for one of my two conditions (Male, Female):

erpplot(erpdta.Male, frames=time_pt,xlab="Time (ms)",lty=1,ylab=expression(Amplitude~(mu~V)),bty="l",

cex.axis=1.25,cex.lab=1.25)

I would like to add the ERP wave for the Female condition to this same plot. What code would I need to achieve this? I've tried adding an additional erpplot and I've also tried using the points and lines functions and am unable to get this working. I appreciate any help!

Best,

Ariel
