Hi,

Was wondering if it is possible to pass function name as a parameter, smth along this line

param.to.pass<-c(1,'max','h')

dd<-function(dfd, param=param.to.pass,...){   ttime.int <- format(ttime,fmt)
  data.frame(

     param[3] = tapply(dfd[,param[1]],ttime.int,param[3]),
         ...)

   }

I know there is a as.formula expression but not quite sure if there is some way to accomplish what i need.
Thanks
