similar to: Significant difference of coefficients in glm with factors?

Good afternoon, I REALLY try to answer to my question as an autonomous student searching in the huge pile of papers on my desk and on the Internet but I can't find out the solution. Would you mind giving me some help? Please. ######################################### I'm trying to use glm with factors: > Pyr.1.glm<-glm(Pyrale~Trait,DataRav,family=poisson) If I have correctly

The code below illustrates some points about results from tapply that I find strange. I wonder if they are intended and if so why it is so. 1) When you make a table the dimnames is a *named* list, tapply returns an unnamed list. 2) data.frame behaves differently on an array and a table. Is this an intended feature? 3) For tables class(TAB) and attr(TAB,"class") both return

[my original message to s-news & r-help is attached ] No one possessed or knew of any S/R code for the sequential t-test. Also it doesn't appear in the SAS index. One or two suggested obtaining the S+ seqtrial software which may (or may not) cover this, but this seemed to be a bit of a "hammer to crack a nut". I have written a function based on the treatment in Wetheril

Hi - I'm just starting out with R and have come up against a problem with what should be a simple operation. I'm plotting a range of safety standards for 7 different chemicals. I don't want the standard box and whisker plot - I just a dot for each value. Whilst using "plot.default" I get the error "invalid xlim value" - which is confusing since using the same script

Hello, I would like to do a partial least square discriminant analysis (PLSDA) in R using the package "ropls" Which is in R available via the R command : source("https://bioconductor.org/biocLite.R") When I try to do a PLSDA using my own data. The impact of two genders (AP,C) on 5 compounds measured in persons (samples) should be illustrated. When I try to do a PLSDA I get

Dear all, I've just a little question ...

Dear all, I'm trying to receive a call from a VoIP provider to my Asterisk which is behind a router, with a port forwarding (5060). This configuration has already been validated with another VoIP provider, but in the present case, not. I suppose (thanks to the sip trace) my asterisk is not able to answer a call which need Prack. My asterisk answer : ' SIP/2.0 420 Bad extension ...

Hi folks, I have five imputed data sets and would like to apply the same recoding routines to each. I could do this sort of thing pretty easily in Stata using MIM, but I've decided to go cold turkey on other stats packages as a incentive for learning more about R. Most of the recoding is for nominal variables, like race, religion, urbanicity, and the like. So, for example, to recode race
