Hi!
How to change  parameters of a function during runtime.
instead for example calling with column names
subset(airquality, Day == 1, select = -Temp)
    i want call subset with column indices something like this.
subset(airquality, xxx(names(airquality)[4])> 80 , select =
c(xxx(names(airquality)[3]),xxx(names(airquality)[4])))

In genereral I am interested in changing the  parameters during runtime.
for example i want to call at runtime
instead of:
plot(x,y,col=1).
plot(x,y,log= "xy")
by calling:
myarg<-"log"
myargval<-"xy"
plot(x,y,xxx(myarg,myargval))
It is possible to do that?

Sincerely Eryk
