how to chage values in data frame to NA iside a function
Dear all
I have a function in which I would like to change some values to NA according to
some condition.
dropout<-function(y, nahr=FALSE,...) {
<some stuff for computing an index>
if (nahr) y[index]<<-NA
invisible(index)
}
in case y is a vector all works OK but if it is a part of data frame by calling
dropout(df$y) or dropout(df[,number]) no change is done.
Please can you
