hi, R-users
   I have a data.frame for example  test$newdataday24 and test$newdataday48
I can plot them by
plot(test$newdataday24)
but now i want to plot different data by define a variable to describe them
dayno<-c(24,48)
newnam<-paste("test$newdataday",dayno,sep="")
plot(newnam[1])

but i failed,the error message said that something wrong with plot.window

what can i do to fix my script ? thanks
