Usage of p/d/qnorm
...pect to a varying x cut off value.
How could one possibly formulate using p/d/qnorm e.g. the specificity:
f(x)= number of positive tests at cut off x / total number of truly
positives ?
Thank You,
Ralf Herold

ESRI shape file import and time-space models
Dear R user,
I am running R under Windows 2000.
I am looking for a routine for importing
- shape files (ESRI) into R
- dbase files (FOXPRO) into R
and I am looking for time-space models for description and prediction of
Bernoulli-, Binomial- and Poissonvaraibles.
Thank's a lot for a reply.
Sincerely yours,

Percentile function
Is there an R function that inputs a value and a vector, and
returns the percentile corresponding to the value?
Something like
pvalue<-function(x,vector){mean(x>=vector)}
but with interpolation.
Given the above function, is there a way to do the following
without the loop:
for(i in 1:10) y[i] <- pvalue(x[i],vector)
where x and y are numeric vectors of length 10?
