I have a data frame (gom) or a matrix of trace metal data and some other
observations from water column samples taken at sea (e.g., 19 samples
(rows), 19 variables)
I can calc. the rank individually from each column of the attached object.
How can I create a matrix that contains the ranked data for each variable
(either 1-19, ties=avg)?
For example:
>gom<-read.csv ("gomdata.csv")
>rank(Phaeo)
[1] 3.5 1.0 2.0 5.0 15.0 19.0 12.0 7.0 3.5 13.0 17.5 9.0 6.0 14.0
16.0
[16] 11.0 9.0 9.0 17.5
I'd like to return an object (e.g., "gomr <-" ) that has each column
individually ranked (for data normalization, btw).
