modify a data.frame within a function
...values. I want to do it within a function, but can not assign the modified column back into the data frame. It was easy and successful without a function, so I suspect the problem is the call of the single column within the function.
removedata<-function(datafull,var.removed)
{
attach(datafull)
NArandom<-rnorm(n=length(var.removed), mean=0, sd=1)
for (i in 1:length(var.removed))
if(NArandom[i]>0)
var.removed[i]<-"NA"
datamiss<<-datafull
detach(datafull)
}

What to do with a inconsistency in rank() that's in S+ and R ever since?
...desire e.g. ties.method = "average" except for NAs!?
I am aware that the prototype behaves like this and R ever since behaves like this, however to me this appears very unfortunate. In order not to 'break' existing code, what about adding ties.methods {"NAaverage"|"NArandom"|"NAmax"|"NAmin"} that behave consistently?
Best regards
