I am having a problem with NA handling in capscale function.
as I understand it from the help capscale should permit NA values when
na.action=na.mit or na.exclude,
however I am getting the error
Error in X[nas, , drop = FALSE] : incorrect number of dimensions
trivial example is pasted below.
library(vegan)
mydist- matrix(1:25, 5, 5)
mydata-matrix(rnorm(1:25),5,5)
mydata[3,1]-NA
mydata-data.frame(mydata)
capscale(mydist~X1+X2+Condition(X3),data=mydata,na.action = na.omit)
Thanks

It is failing within the formula parsing code because ordiParseFormula
thinks the response is a matrix but it was getting a dissimilarity
matrix in class dist form.
I think Jari has just fixed this in the R-Forge svn sources, but that
revision has not yet been built on the R-Forge build system. Check back
here later:

Thanks for the report.
