Hi Subhamitra,
1. Here I manufacture some data so that the example is "reproducible", that
is anyone can run the code and get the same output that I do. Yes,
veh1...veh38 are the names of the variables.
2. Here I join the 38 variables I created into a data frame, which I think
is the input for your plotting routine. This names of the columns of the
data frame become the names of the variables.
When you say that you want the column names as the "header" (title) of each
plot, I think if you change the plotting loop to this:
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="MPG",main=names(mpg)[i])
dev.off()
you will get what you requested. Remember that I have done this in base
graphics, not ggplot.
