Hi,
I am looking for a documentation describing how to manipulate the
"..." . Searching R-intro.html gives to many not relevant hits for
"..."
What I want to do is something like this :
image.2 <- function(x, col , ...){
# function is manipulating colors (adding a few)
# since it changes colors it needs to update breaks if defined.
breaks <- list(...)$breaks
if( !is.null( list(...)$breaks ) ){
#manipulate breaks
image(x, col, breaks = breaks ,...)
}else{
image(x,col ,...)
}
}
but in order to get it working I will need to remove breaks from ...
since otherwise I am getting multiple defined argument for breaks.
So how to manipulate the "..." argument? Or should I use a different pattern
best
