Dear Dr. Snow,

Thank you for your reply.

1. Are you doing the 2 sample KS test? Comparing if 2 samples come from the
same distribution? -Yes, I am doing 2-sample KS test

2. With 3,000 points you will still likely have power to find meaningless
differences, what exactly
Is there any way to use expression() in legend labels with ggplot2?
It seems that things like
scale_shape_manual(value = c(
x = expression(italic(x)),
y = expression(italic(y))
))
don't work.
Thanks very much :)

I am using the svm function (e1071 package) to classify two groups using a

procedure.
(A) On one hand I use the setting cross=10 in the svm function to run 10
cross-validation iterations and to get an

Hi,
I need to do a calculation in R which involves adding the estimate of a
numerical integration with another number - however, if I add the number to

with a number with error), I get the message 'non-numeric argument
Any answer to this?
I really need to compare a mixed model with binomial error against the same
model without the random effect. I would use anova() but I don't know how to
specify both models in order to make them comparable.
Thanks for any answer

What version of R are you using?
x = ecdf(rnorm(50)); y = ecdf(rnorm(50))
plot(x); lines(y, col=2)
works for me on R 2.13.1. Specifically, there is a lines.stepfun method
(albeit non-visible) which handles this.

Hi Arne,
my problem persists. I am still using censReg [version - 0.5-7] to run a
random effects model in my data (50,000 cases), but I always get the

Can you fit a simpler model successfully? I would play around with
all your RHS variables to try to see if there is any particular one
that causes the estimation problems. Two ways I would do this would
be to drop them one at a time, or to start from an intercept only
model (i.e., transfers.cap
Or just ask let the second plot know to add it to the existing plot:

note the limits are set by the first plot, so watch out for that. You

Given that your response variable is binary and, consequently, you should
