How about doing something like this:
fn <- function(n,cut=0.001,m=1000)
{
p <- ppoints(n)
p <- p[pmin(p, 1-p) < cut]
q <- pt(seq(qt(cut,df=1
Dear R helpers,
I generate a qq plot using the following function call.
qqmath(~val|ind,data=xx
,distribution=function(p) qt(p,df=19)
,ylab="Sample Quatinles"
,xlab="Theoretical Quantiles"
,aspect=1
,prepanel = prepanel.qqmathline
,panel=function(x,y)
