Line Graph in R is a basic chart in R language which forms lines by connecting the data points of the data set. You can end the incomplete line with an operator (like +, /, <-, and so on). In ggplot2, the parameters linetype and size are used to decide the type and the size of lines, respectively. If more fine tuning is required, use abline(h = ., v = .) See Also. Becker, R.
