Hi R-users, can anyone explain me how to play around with the options of the bootstrap calibration curve obtained using the calibrate() function in Design package? I am trying to colour the diagonal, i.e. the ideal curve, in red, and also hide the bias-corrected curve. Thanks, Dave _________________________________________________________________ Show them the way! Add maps and directions to your party invites. [[alternative HTML version deleted]]
It's rather simple to get the code and add modifications. You wanted
the dashed line to be red? (To find out what the underlying function
name is, you use methods(plot):
The dashed ideal line plotting function is not set up to accept
parameters. so you need to alter the code. Use this as a guide:
>plot.calibrate <-
function(<snipped outputy from original parameter list....
{ <snipped code from function body....
### Just change the code at the end of the function body to:
abline(0, 1, lty = 2, col="red")
}
plot(cal)
#Voila! Red dashed line.
