Function call with a list of arguments

Use do.call to call a function with a previously built list of arguments:

# Define the arguments

args.legend <- list(
  x = "topleft"
  , legend = c(1,2)
  , fill = c("red","blue")
  , xjust = 1, yjust = 1)

plot(1:10, 1:10)
# call function with the arguments' list
do.call("legend", args.legend)
