thanks for your effort.
to be more precise:
ID , OS, time and many more are the columns.
each entry is a row.
when I do:
x <- unique(dataset$ID)
It just gives me a list of all IDs (levels).
I want to get a dataframe where just one entry (row) for each ID is
userA , Win, 12:22
userA, OSX, 23:22
userB, Win, 04:44
should only give me row 1 and row 3...
