Function Definition Layout

20200105

resume

Align function arguments in a function definition one per line. Aligning the = is also recommended to make it easier to view what is going on by presenting the assignments as a table.

Preferred

show_dial_plot <- function(label       = "UseR!",
                           value       = 78,
                           label_cex   = 3,
                           label_color = "black")
{
  ...
}

Alternatives

show_dial_plot <- function(label="UseR!",
                           value=78,
                           label_cex=3,
                           label_color="black")
{
  ...
}

show_dial_plot <- function(
                    label="UseR!",
                    value=78,
                    label_cex=3,
                    label_color="black"
                  )

Discouraged

show_dial_plot <- function(label="UseR!", value=78,
                           label_cex=3,
                           label_color="black")
{
  ...
}

show_dial_plot <- function(label="UseR!",
  value=78,
  label_cex=3,
  label_color="black")
