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

[Jim Lemon]

Hi Subhamitra,
As Bert noted, you are mixing base and grid graphics. Here is a simple
way to get a plot like what you described. It will probably take more
work to find what you actually do want and discover how to get it.

for(i in 1:38) assign(paste0("veh",i),rep(sample(10:35,1),10)+runif(10,-4,4))
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)
pdf("mpg.pdf",width=30,height=12)
par(mfrow=c(4,10))
for(i in 1:38)
 plot(seq(1,500,length.out=10),mpg[,i],type="l",xlab="Distance",
  ylab=names(mpg)[i],main="MPG by distance")
dev.off()
