Hello Instead of reading in group1.txt I want to read in groups1 for the first iteration of i, then groups2 for the second and so on. Obviously I can't use groups(i) but assume there is a way to do this. group<-read.table("C:/Data/April 2005/group1.txt",header=T) thanks in advance Meredith

I know I'm not supposed to use them... but they're just so easy! I have trouble defining an appropriate function for plyr or apply! data<-rnorm(144) groups1<-c('a','b','c','d') groups2<-c('aa','bb','cc','dd') machines<-1:12 df<-data.frame(machine=machines,group1=groups1,group2=groups2,U=data,V=2*data,W=data^2,X=1/data,Y=data+2,Z=2/data) So... I am currently generating a table...

The cenmle function is used to fit two sets of censored data and test if they are significantly different. I can print out the results of the analysis on the screen but can't seem to figure out how to access these results in R and assign them to new variables, e.g., assign the slope calculated with cenmle to the variable m. Any suggestions? Tom -- View this message in context:

Hi Ansely, As Jim points out we really need some sample data to go with the code. Have a look at ?dput which is the best way to supply sample data here or have a look at http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and/or http://adv-r.had.co.nz/Reproducibility.html for some general suggestions on asking questions here---including discussions of using

Hello, *Error in tx %*% comb : non-conformable arguments* Suggestions greatly appreciated. I am a beginner and this is my first time posting. I would like to get the summary for indicator species analysis, using package indicspecies with multipatt. I am getting errors, I believe, do to my data organization. After reorganizing and reorganizing, nothing has helped. > data<-
