Thankyou all by the comments and sorry for not sending in the adequate format. I don't have the chance to make txt archives as open office doesn't do it. I'm attaching the data in excel. Please let me know if this is ok. The graph that is wierd to me is the BBSA vs AMGP. It is supposed that AMGP

.csv format is still not accepted by the server. When I say it needs to be a .txt file I mean it it needs to be a .txt file. You need to change its extension to .txt to prevent your mail client from labeling it as csv which is a different type even though I, too, would have thought they

Re: [R] GLM Help

I think you are looking for ~ Region + Region:Helpers - 1 a.k.a. ~ Region/Helpers - 1 Notice that these are actually the same model as your glm3 (and also as ~Region*Helpers), only the parametrization differs. The latter includes an overall Helpers term so that the interaction coefficients

Hi all, I have a large set of data that looks something like this, although this data frame is much smaller and includes made up numbers to make my question easier. x.df - data.frame(Region = c(A, A, A, A, A, B, B, B, B, B, B, C, C, C, C), Group_ID = c(1:15), No_Offspring = c(3, 0, 4, 2, 1,

[R] GLM Help

Hey all, I am attempting to replicate my results achieved in another program within R (so I can expand my options for methods). I am trying to run a GLM (Family = Poisson) for count data in R. Some of my variables are factors and I am under the impression that the function glm() cannot run a

Re: [R] GLM Help

Are you sure your variables are categorical or numeric? Of course, glm differentiates these two kinds of variables. For example, I ran the same variable with different modes, the results are very different. dat-data.frame(y=rpois(100,5),xf=as.factor(sample(1:4,100,replace=T)))
