...scale on the y-axis, you get a straight line. My question is whether it is possible in R to use a "probit" scale in a "plot". For example on the following webpage you can see an application of how I would like to use a probit scale: http://www.physiol.cam.ac.uk/staff/carpente/recinormal.htm And if a probit scale is not available, what would be the most effecient way of 'simulating' a probit scale using the plot comment. Many thanks for your help!!!
