Hi
Do not use attachment, copy result of dput(object) to your mail instead. This enables us to see how your data really look like.
I get different error.
> widesII(used, available, avknown = TRUE, alpha = 0.05)
Error in widesII(used, available, avknown = TRUE, alpha = 0.05) :
used and available matrices should have the same number of habitats
The error is due to fact that row names were read as column of data frame. After correcting this I got the same error as you.
> widesII(used, available, avknown = TRUE, alpha = 0.05)
Error in as.vector(X) %*% t(as.vector(Y)) : non-conformable arguments
I checked the help page and I noticed that
a
for widesI and widesII, a vector with named elements describing the sample or the proportion of available resource units. For widesIII a matrix or a data frame giving the number or the proportion of available resource units for each animal (in rows) in each resource category (in columns)
but your "available" is a data frame.
When I change it to named vector (as required)
> dput(avail)
structure(c(0.06, 0.13, 0.16, 0.15, 0.06, 0.17, 0.12, 0.04, 0.09,
0.02), .Names = c("Riparian", "Conifer", "MtShrub1", "Aspen",
"RockOutcrop", "Bitterbrush", "Windblown", "MtShrub2", "PresBurn",
"Clearcut"))
widesII came with result without complain.
> widesII(used, avail, avknown = TRUE, alpha = 0.05)
************** Manly's Selection ratios for design II ********
1. Test of identical use of habitat by all animals
(Classical Khi-2 performed on the used matrix):
Khi2L1 df pvalue
So the lesson is:
1. Read the help page.
2. Look to your data by ?str
3. When your data are as expected by the function, check if there is no syntax problem.
4. Try to simplify the example and send it to help list preferably by ?dput.
Cheers
