Dear list,
I have been struggling for some time now with this code... I have this vector
of unique ID "EID" of length 821 extracted from one of my dataframe (skate). It
looks like this:
> head(skate$EID)
[1] "896-19" "895-8" "899-1" "899-5" "899-8" "895-7"
I would like to remove the complete rows in another dataframe (t5) if any of
the t5$EID is equal (a duplicate) of skate$EID.
I was able to get my 'duplicated' dataframe in t5 of all my matching EID as
follow:
> xx<-skate$EID
> t5[match(xx,t5[,26]), ]#gives me a dataframe of all matching EID in skate$EID
record.t trip set month stratum NAFO unit.area time dur.set distance
8948 5 896 19 11 221 2J N12 908 15 8
8849 5 895 8 10 766 3O R36 1650 16 8
9289 5 899 1 12 743 3L V26 2052 15 8
9299 5 899 5 12 746 3L W27 1129 14 7
Where t5[,26] correspond to t5$EID column. I'm sure it's simple, but I'm not
sure how to remove all of these now from my t5 dataframe! Tips would be very
much appreciated!
Thank you!
