glm models with more than one response
...concentrations at sample point
locations. Ultimately I'd like to use the probabilities for each response
category in a simulation model such that these probabilities are used to
define a realized ecological niche.
When I try the following it works for a single response.
Typha.glm <- glm(fwc$VegType == "Cattail" ~ fwc$TP + fwc$TC + fwc$TN +
fwc$BD + fwc$LOI + fwc$Total_Mg, family = poisson)
But if I try this without specifying a specific VegType it fails.
plants.glm <- glm(fwc$VegType ~ fwc$TP + fwc$TC + fwc$TN + fwc$BD +
fwc$LOI + fwc$Total_Mg, family = poisson)

subset
...those rose from the original data
frame. I think I can create a new data frame without the duplicates
using subset. I have tried:
Subset(x,!x1) and subset(x,!x[x1,])
I can't seem to find the correct syntax. Any advice.
Thanks in advance

I want to create a new uniform random matrix [a] that is filled with 0's
and 1's but constrained so that the row and column sums are the same as
in [P]. Does anyone know how to accomplish this?

It appears that the code works for the first two if/else statements and
then fails there after. Any suggestions?

Missing Content-Length header breaks ActiveResource 3.1 on create
Hi,
I''ve recently moved a 3.0 app ta 3.1 and am finding that
ActiveResource breaks after a successful post because we now check for
the presence of the Content-Length header[1] after a successful create
(basically whenever the API returns a 201). The API is also on 3.1,
and this only happens on staging/pre-prod/prod.
I''m still investigating, but one thing that is clear is that
