R has great plotting capabilities and this forms an important part of data analysis. Two methods are most commonly used: plot function of base R and ggplot and other functions of ggplot2 package.
Plot function is good for simple graphs but beyond that complex syntax is needed.
> xx = c(1,3,6,8,19)
> yy = c(13, 46, 53, 78, 110)
> plot(xx, yy)
To plot age versus lwt of bwdf dataset:
> with(bwdf, plot(age, lwt))
Note that 'with' function creates a micro-environment where the variable are looked for in the bwdf dataset. Otherwise, one can also get same result with following command:
> plot(bwdf$age, bwdf$lwt)
There are many other plot commands in base R also such as barplot and boxplot.
