Dears,
I'm having a weird behaviours when setting arguments in functions.
fn <- function(x, st="mean", b=NULL, col.range="black", ...){
dots <- list(...)
cat("col.range =", col.range, "\n")
cat("dots =\n")
print(dots)
}
fn(1, b=2,col="red")
# Output
col.range = red
dots =
list()
Why 'col' arguments are not in ellipses, but setting col.range to 'red'?
If I change the position of ellipses
fn2 <- function(x, ..., st="mean", b=NULL, col.range="black"){
dots <- list(...)
cat("col.range =", col.range, "\n")
cat("dots =\n")
print(dots)
}
fn2(1, b=2, col="red")
# Output
col.range = black
dots =
$col
[1] "red"
It works! I'm using R version 3.2.2.
Best regards!
Mario
