[R] HELP relevel INTERCEPT-COMPARISONS
Dear colleagues, How can I do to "relevel" the intercept? I need that the treatment "Db" be the intercept, and have p-values for the comparisons with the others treatments. I used the function "relevel" but it did not work out to have what I want.

[R] GLM and POST HOC test INTERPRETATION
Dear colleagues, I am analyzing a data set of 68 values (integers). In some treatments (exactly 6) the values are "zero". Because I record 0 in my measurement (or really a small value below zero) My experiment is designed in such a way that I record values for 6 treatments at 2 times. Replicates are different in each combination time-treatment. I am running a GLM , poisson distribution, for ANOVA I used Chisq, and for the POST HOC test I used Tukey. I try to detect if interaction is significant, so I build the script: expresion~time*treatment Effects of time, treatment are interaction are significant. However, when I run the script for Tukey comparisons, I only get 15 comparisons. Of course I cannot interpret that: these comparisons are the same for Time 1 and Time 2, since there is a significant effect of time. Moreover, I got a warning message : covariate interactions found. I dont know if I am doing right? I dont know what to do?
