Hi,
something like this might help:
## your toy data set
d <- data.frame(SITE=rep(c("I","II"), each=3),
SPECIES=rep(LETTERS[1:3], 2),
Replicate1=c(1,2,1,4,1,6),
Replicate2=c(3,5,0,2,0,3),
Replicate3=c(0,1,2,0,0,3))
## required for functions inflate, stcs and mefa
library(mefa)

Hi Michael,
matrify() world work if I had only one column with abundances. In my
original data frame I have 1 sample.id column, 1 taxon column but 7
abundance columns (corresponding to 7 replicates taken within each sample).
I am quite sure that the cast()function within the reshape package shou

Hello everyone!
I'm having a problem in casting a data frame with the reshape package. I
have an original data set of species abundances in replicate samples at
certain sites, with the following form:
SITE SPECIES Replicate1 Replicate2 Replicate3
