Dear R users: I have a problem about catch the value from function. I have following two functions (part): fbolus1 <- function() {......... par<-data.frame(Parameter=c("kel","Vd"),Initial=c(0)) check(par) .....} check<-function(par) { if (par[ ,2] <= 0){ cat("\nEnter again (y/n) ?\n\n") ans<-readline() if (ans == "n" ){

...es drugA/no drugB, yes drugA/yes drug B, omitting the fourth group of no drugA/yes drugB. I think we can not investigate interaction between drug A and drug B, can I still run model using R as usual: response variable = drug A + drug B? any suggestion is appreciated. Thank you very much!

...ype="response") gives me all "NA"s. it works for level=0 (the fixed effects), but not for level=1. When i use newdata=traindata, predict function works perfectly. i wonder if this is a problem with predict function or it's some bug in my code? Thanks much for your help!

Hi, I am writing a kernel module which works with netfilter. If a certain condition matches, I want to create a qdisc, a class and a filter inside the kernel module. How can I create qdisc, class, and filter inside the kernel?

...g it is better to use dat[["variable"]] than dat$variable. So your code could be pfas.pheno[[cat.var]] <- NA pfas.pheno[[cat.var]][pfas.pheno[,i] <= quantile(pfas.pheno[,i],0.25, na.rm =T)] <- 0 etc. Untested.
