[R-sig-eco] cozigam
hi i try to find regression between clupeidae,with temperature,salinity and depth. the response variable is inclued many zero ( 86 from 133 observed) therefore i used this code : res - cozigam(Clupeidae~s(temperature,salinity)+s(depth), constraint = proportional, family = gaussian) the result: iteration = 2norm = 1.001743 iteration = 3norm = 0.3377464 iteration = 4norm = 9.172232e-05 == estimated alpha = -0.5337883 ( 0.1789113 ) estimated delta = -0.0009891505 ( NaN ) == Warning message: In sqrt(V.theta[2, 2]) : NaNs produced what is exactly meaning? thanks for your help -- Mahnaz [[alternative HTML version deleted]] ___ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
[R-sig-eco] error message with function rda of package vegan
Hello all,
Apologies for cross postings.
I am running the function rda of the vegan library, like I did many
times without having troubles, and I get the following error message:
Error in if (rank) { : argument is not interpretable as logical.
I am just testing a response matrix against a single explanatory
matrix, which is the result of a model matrix with 4 dummy variables
(coding for a factor of 5 levels).
myrda-rda(resp, expl)
When I, for instance, change the response matrix, it goes well.
Does anyone know what might be happening?
Thanks,
Duarte

Not without a reproducible example, I'm afraid.

[R-sig-eco] error message with function rda of package vegan
Hi,
Thank you for your reply. It's not easy to give you a reproducible
example, because this is a very specific case (something in my data ,
I believe). The only way is to send the data and try yourself. If
someone is willing to do that, I would be grateful.
I can send the response matrix and the explanatory matrix, and all one
has to do is load library vegan, load the data, and run the rda
function:
library(vegan)
resp-read.table(resp.txt, head=F, sep=\t)
expl-read.table(expl.txt, head=F, sep=\t)
myrda-rda(resp, expl)
Thanks,
Duarte

Feel free to send your data to me, off list. I'll take a look at what might be
going on inside vegan.
