Dear Lister, plot() is using the data range as the default limits of yaxis. Is there any way I can change the limits? I just look at the help of plot() and par() and couldn't find answers.

I have experience with R on linux before but never use R on unix.

Dear Listers, My post might be somewhat OT. Currently, I am trying to use flexmix to build a finite mixture model. For instance, I am getting the prior probability and coefficients for each latent class from training data. Is there a way to get the posterior probablity and prediction of a new dataset? What I am thinking is to apply the prior prob and coefficient from training set to testing data

Dear Lister, I understand merge() can be used to join 2 data frames based on 1 variable. But how about merge based on more than 2 variables?

Dear All, Is there a emacs/xemacs for unix without compiling it? If it is possible, I prefer something that I can use immediately after putting it on the unix server.

Right now, I am using SAS and S+/R. As a new year resolution, I am planning to learn a scripting language. from statisticians' point of view, which scripting language is worth to learn, perl, python, or any other recommendation? (Most likely, I will be learning it in windows.) Since I am not in research, I will prefer one widely used in industry and related to statistical work. if you

Your surest bet is to look into S+, not R, since the former does 'integrate' with Microsoft applications. To what extent, I don' know. This is a desirable feature (IMO) and a reason to use S+ rather then R (already discussed in different thread).

Hi R-experts, I have data from four conditions of an experiment. I tried to create four subsets of the data with read.table, for example, read.table("Experiment.csv",subset=(condition=="1")) . I found a similar post in the archive, but the answer to that post was no. Any new ideas about reading subsets of data with read.table? Thanks! Feng [[alternative HTML version

I checked GlmmML package. However, it can only do binomial and poisson distribution. How about others such as gamma or neg binomial? Thank you so much! wensui

I remember in one slide of Prof. Ripley's presentation overhead, he said the most popular data analysis software is excel. So is there any resource or tutorial on this topic? Thank you so much!

Dear Listers, If I have several glm objects with names glm1, glm2.... and want to apply new data to these objects. Instead of typing "predict(glm1, newdata)..." 100 times, is there way I could do so in a loop? Thank you so much! wensui [[alternative HTML version deleted]]

Dear R community, I have a dataframe with say 100 different variables. I wish to regress variable 1 separately on every other variable (2-100) in a linear regression using lm. There must be an easy way to do this without loops, but I have difficulties figuring this out... Can you please help?
