How to test if two C statistics are significantly different?
Hey all, In order to test if a marker is a risk factor, I built two models (using cox proportional hazard model). One model included this marker, and the other is not. Then, I use R package risksetROC to test how much predictive value did the marker add to this model. I get two C statistics by analyzing the linear predictors of the two models into this package. The qustion is How to test if two

getMethod(s) and var.test
Hi, How do I retrieve the var.test() function code? I had a similar problem once before with another function but getMethods() solved the problem then. Now I tried several combinations for var.test() without success.

Using substitute in nested function calls
Dear List members, I really, like the feature that one can call R functions with mathematical expressions, e.g. curve(x^2, 0, 1) I wonder, how I can construct in a simple way a function like mycurve = function (expr) {...} such that that a call mycurve(x^2) has the same effect as the call curve(x^2, -100,100) Below is some code that works, but it seems much to complicated: it first

Replace a for loop with a function
Hi all, I would like to replace the for loop in the code below with a function to improve the speed and to make the script more efficient. The loop creates a vector of integers (x) with the probability of f for each integer. The length of f is variable, but sums to 1. I tried to use a function with optional arguments which did not work. Here is the code: f <- data.matrix(c(0.5,0.15,0.35))

"Plotting" text?
I noticed that the text() command adds text to a plot. Is there a way to either make the plot blank or add text to a "blank sheet". I would like to "plot" a page that contains just text, no plot lines, labels, etc. Suggestions? Kevin [[alternative HTML version deleted]]

density estimate
Hi, I have a vector or random variables and I'm estimating the density using "bkde" function in the KernSmooth package. The out put contains two vectors (x and y), and the R documentation calls y as the density estimates, but my y-values are not exact density etstimates (since these are numbers larger than 1)! what is y here? Is it possible to get the true estimated density at each

Possible or not possible: serif axis labels with plotmath [but everything else sans serif]?
Dear expeRts, I it possible to have serif labels in the following plot? x <- 1:10 y <- x plot(x, y, type="b", xlab=expression(x[1]), ylab=expression(x[2])) I know that one can use pdf(, family="serif"), but then also the axis tick marks are printed in serif font. Apart from the fact that it may not look nice, I'm just interested if one can have serif axis labels
