[R] [R studio] Plotting of line chart for each columns at 1 page

[Subhamitra Patra]

Hello Sir,

Thanks, I'll check them out.

But, I am not understanding 2 points of your suggestion.

1. In the line,* "*for(i in 1:38) assign(paste0("veh",i),rep(sam
ple(10:35,1),10)+runif(10,-4,*4))", *what veh, rep(sample(10:35,1),10)
+runif(10,-4,4)) indicate? Here veh indicates columns right?
*2. In the
line, mpg<-data.frame(veh1,veh2,veh3,veh4,veh5,veh6,veh7,veh8,veh9,veh10,*
* veh11,veh12,veh13,veh14,**veh15,veh16,veh17,veh18,veh19,**veh20,*
* veh21,veh22,veh23,veh24,**veh25,veh26,veh27,veh28,veh29,**veh30,*
* veh31,veh32,veh33,veh34,**veh35,veh36,veh37,veh38)  ** , *veh[i]
indicates column sequence, right? I need to give column names as the header
of their respective graphs. Please suggest me How to add this?


I am very new to R and therefore asking you these queries which might be
simple for you.

I expect positive help from you.

Thanks for your kind help.
