Dear All, I would like to merge a data frame such as:
> basetab subject dose cmax 1 1031 50 21.8 .... with the result of a by processing such as: > tmax<-by(pkga,subject,f.tmax) > tmax subject: 1031 [1] 6 -------------------------------------------------- f.tmax being a function written by H. Nguyen (in applied statistics in the pharmaceutical industry). pkga is a data frame with subject conc time variates. The aim is to have a single data frame with subject dose cmax tmax etc (AUCs) ... so that I can do summary stats and plots by dose. I have tried unlist without success. Thanks for any help. Kind regards, Jean-Louis ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
