I plotted the values using this code:

png(filename="q.png", width=3000, height=1600, units="px")

but the values on x and y axes appeared to be too small. I want to magnify them. How do I do that?

    I suspect that you need to change it when you plot the graph, for example:

     par(mar=c(4,5,1,1))
 plot(rnorm(30), xlab= "Big font", ylab = "Big font", cex.lab = 2, cex.axis = 1.5)

    Example:

    EDITED 1: To change the title size:

    par(mar=c(5,5,4,1))
plot(rnorm(30), xlab= "Big font", ylab = "Big font", 
    cex.lab = 2, cex.axis = 1.5, cex.main=3, main="Big Font")

    enter image description here

    EDITED 2:
    Shaded plot area. Not sure if this is the best way to do it. There may be simpler and more elegant ways to shade the plot area.

    a = rnorm(30)
par(mar=c(5,5,4,1))
plot(a, xlab= "Big font", ylab = "Big font", type="n",
     cex.lab = 2, cex.axis = 1.5, cex.main=3, main="Big Font")
x <- par("usr")
rect(x[1], x[3], x[2], x[4], col = "grey")
points(a, pch=19)
