argument which I will pass on to subset() somewhere inside my function.
I would use the example of .() function from plyr package in this case:
.<-function (...){
structure(as.list(match.call()[-1]), class = "quoted")
}
myfunction<-function(table, extraction) {
table2<-subset(table, eval(extraction[[1]]))
return(table2)
}
myfunction(iris, extraction = .(Species=="setosa"))
You can pass as many arguments in .() as you wish and index correspondingly in
myfunction afterwards.
HTH.
