Hello,
Just to add to what others have said, I believe you haven't understood
the dots argument. Where you to change the function in the package and
the correct form would be
myplot <- function(x,y, ...) { plot(x,y,...) }
Hope this helps,

Thanks for reply.
as I said , the function in the package is like
myplot <- function(x,y) { plot(x,y) }
not like
myplot <- function(x,y) { plot(x,y,...) }
And I cant change the function inside the package!!
So , in this case how to solve the problem ?

Subject: Re: [R] Override/Insert (Change) a value (default value) inside a
function
Dear Mohammad Tanvir Ahamed,
Re:
Hi!,
Lets I have a function form a package.
The function is, as an example,
myplot <- function(x,y) { plot(x,y) }
Now I can use the function according to function's defined argument.
x<- sort(runif(200))
y<- 1:200
myplot(x,y)
Now I want to input extra argument or override default value of plot inside the
function myplot.
If I use myplot (x,y, col = "red", cex = 0.1 ) it does not work . I clearly
understand , why it does not work .
But in this situation how can i solve the problem ?
That's where the three-dot argument is for.
See "Introduction to R", paragraph 10.4 The ‘…’ argument.
Succes and
best regards,
Frank
