Hi Nevil,
As I don't have the filematrix package this is really an "any suggestion":
FM[,which(colnames(FM) %in% c("one","three"))]

Maybe the following is a solution:
# load package needed
# QSutils is on Bioconductor
library(QSutils)
# here some exemplary data - these are the data from Pilou 1966 that are
used
# in the second example of Hutcheson, J theor Biol 129:151-154 (1970)

Hello,
No, it's not. That's the Shannon diversity index, the test the OP is
looking for is a t-test for Shannon diversity index equality. The index
itself is easy to code. A very simple example, based on ?vegan::diversity:
library(vegan)
data(BCI)
H <- diversity(BCI[1,])# just first row

I have a data set of rainfall from 12 weather stations over 10 years. I
would like to model it using a Spatio-Temporal model in R.

Is there a way to get columns out of a filematrix using the column name
directly in the same way that you can with a regular matrix?
library(filematrix)
M<-t(matrix(1:3,3,4))
colnames(M)<-c("one","two", "three")
M
#Extract column
M[,1]
M[,"one"]
M[,c(1,3)]
M[,c("one","three")]
FM<-fm.create.from.
Could it be that the test you are looking for is implemented in the
vegan package (function diversity(... index = "shannon" ...), and/or the
BiodiversityR package, function "diversityresult (..., index =
"Shannon",...)
best,
Karl Schilling

Hi Robert,
You don't provide a self-contained reproducible example, so I am just
guessing here.
I doubt your theory that the error is related to R. More likely the step
that creates a data frame from reading
the CSV is probably resulting in different data frames in the two cases. I
recommend that y
