Hi, In that case, try this: #made up data Coral1<-read.table(text=" Seamount Station Depth Pico Nano Micro Total_Ch Coral 1401 Surface 0.216 3.270 4.240 7.726 Coral 1401 Fmax 0.359 3.890 4.900 9.149 Coral 1401 Below 0.178 1.360 1.210 2.748 Coral 1402 Surface 0.231 4.140 3.670 8.041 Coral 1402 Fmax 0.863 4.340 3.750 8.953 Coral 1402 Below 0.176 0.386 0.214 0.776 Coral 1401 Surface 0.216 3.270 4.240 7.726 Coral 1401 Shallow 0.359 3.890 4.900 9.149 Coral 1401 Deep 0.278 1.860 1.210 2.748 Coral 1402 Surface 0.331 4.940 3.670 8.041 Coral 1402 Fmax 0.493 4.840 3.750 8.953 Coral 1402 Below 0.186 0.486 0.214 0.776 ",sep="",header=TRUE,stringsAsFactors=FALSE) Coral2<-with(Coral1 , aggregate(cbind(Pico, Nano, Micro), list(Depth),FUN=mean)) Coral2[order(order(c("Surface","Shallow","Deep","Fmax","Below"))),] # Group.1 Pico Nano Micro #5 Surface 0.2485000 3.905000 3.955000 #4 Shallow 0.3590000 3.890000 4.900000 #2 Deep 0.2780000 1.860000 1.210000 #3 Fmax 0.5716667 4.356667 4.133333 #1 Below 0.1800000 0.744000 0.546000 A.K.

I know the order is abit confusing, but here is abit more background info to the depths. For the various depths the ships's ctd sampled. surface = ctd @ surface e.g 5m shallow = between surface and fmax e.g. 25m deep = between surface and fmax, but deeper than shallow e.g 50m fmax = ctd sampled at maximum flouresence e.g 100m below = below the fmax e.g. 200m The problem I can't really assign a specific depth value to each as fmax changed depth depending on location. If fmax was very shallow then "deep" and "shallow" was dropped from the predetermined sampling depths. Hope this helps explain what I'm trying to do with the ordering of the data. Thanks for all your help. Been a steep learning curve this last week with R Shot Tinus On Tue, Sep 11, 2012 at 8:16 PM, arun <smartpink...@yahoo.com> wrote: Hi, >The order you mentioned is confusing.
