variable substitution in for loops
...ure out how to just get the value of the variable and nothing else. I've tried space separated, comma separated, tab separated lists and all give the same error. I've tried get(), parse()... no go. Any suggestions?

row-wise conditional update in dataframe
...that didn't work. Doesn't help if I declare variables (vars and ABCtaskNum) in the function declaration either, but then I haven't quite figured out how best to do variable substitutions in R. Thanks for any help.

generate list of variable names
..."factor") else tmp[[i]]<-NULL } factorlist<-names(tmp) ... One problem is that the scope of the counter changes as I drop columns, but there seems to be other problems as well Any suggestions would be welcome. Thanks!

variable substitution
...pick which columns I want to analyze. #Example script varlist<-read.table(/path/to/varlist) for (i in 1:length(varlist)){ res<-mean(Dataset$SOMETHINGHERE_i ) write(res) somewhere } Something like that.

gamm (mgvc) and time-varying coefficient model
Dear R users, I have repeated measurements on individuals. I want to estimate the time-varying effect of a factor variable X (taking three levels), e.g. a model in the spirit of Hastie and Tibshirani (1993). I am considering using the package "mgvc" which implements generalized additive models, especially the function gamm, which estimates generalized additive mixed models, and thus,
