Dealing with Duplicates - How to count instances?
Hi there,
given a data.frame 'data' I managed to filter out entries (rows) that are
identical with respect to one column like so:
duplicity <- duplicated(data[column])
data_unique <- subset(data,duplicity!=TRUE)
But I'm trying to extract how many duplicates each of the remaining rows
had.
Can someone please send me down the right path for this?
