Hello Readers! This is my first post as a member ofR-bloggers. In this post I’m going to talk about the basic plotting in R, fortwo dimensional. This is a tutorial for beginners in R.

Then, here’s the simplest way on plotting a yfunction using points on vector x.

Now, you can modify your plot. Say you want to add atitle on your plot. Then you can just add

**main=”Plot of sin(x) + cos(x)”**, on the code. That is,

Moreover, you can also change the style of yourplot, by changing the type of it. And here are the possible types of plot:

“p” for points,

“l” for lines,

“b” for both,

“c” for the lines part alone of”b”,

“o” for both overplotted,

“h” for histogram like (or high-density)vertical lines,

“s” for stair steps,

“S” for other steps,

“n” for no plotting.

So let’s say we choose type

**“h”**. Then we haveLooking at the plot now, it seems that the lines arevery thin. To make it thicker we need to add an option

**lwd**, which is for the linewidth. And thus, changing the line width and making it thicker, we can give avalue say 2.5.

In addition, you can also change the plotting’character’, by using the

**pch**option in R.To
