1 Line Types in R
2 Line Widths in R
3 Examples: Setting Line Types and Line Widths in R

Here we introduce line types and line widths in R. How to set the line type, and change the line width.

Some Arguments for Line Types & Line Widths in R
Argument	Usage
lty	Setting line type
lwd	Setting line width
col	Set line color

1 Line Types in R

In this section we show the main line types in R for use in plots like density plots and line charts.

This is set with the argument "lty", for example, lty = 1 or lty = "dashed". Options available include, "blank", "solid", "dashed", "dotted", "dotdash", "longdash", "twodash" and so on.

Plot Line Types in R

See examples below.

2 Line Widths in R

In this section we show how to set the line widths in R for use in plots like density plots and line charts plots.

This is set with the argument "lwd", for example, lwd = 1 or lwd = 3.

Plot Line Widths in R

See examples below.

3 Examples: Setting Line Types and Line Widths in R

Here, we show some examples setting the line types and widths as shown above.

Example using a density histogram:

set.seed(123)
dendata = density(rnorm(100))
plot(dendata,
     lty = 2,
     lwd = 3,
     col = "blue")

Line Types and Line Widths in R - Density Histogram

Example using a line chart:

set.seed(1234)
linedata = rnorm(30)
plot(linedata, type = "l",
     lty = "dotted",
     lwd = 1.5,
     col = "red")
