R help - Jan 2009 - don't print object attributes on screen

Dear all;
I have a function written in R that returns as a list of values as
output that has associated some user defined attributes to it. How can
hide these attributes when printing the output on screen? I'm using
R-2.8.1 on WinXP....it's like hiding the attr of the output from the
scale function....
Thanks in advance
PM

Is this what you want:
> y <- scale(x)
> str(x)
 int [1:10] 1 2 3 4 5 6 7 8 9 10
> str(y)
 num [1:10, 1] -1.486 -1.156 -0.826 -0.495 -0.165 ...
 - attr(*, "scaled:center")= num 5.5
 - attr(*, "scaled:scale")= num 3.03
> y
            [,1]
 [1,] -1.4863011
 [2,] -1.1560120
 [3,] -0.8257228
 [4,] -0.4954337
 [5,] -0.1651446
 [6,]  0.1651446
 [7,]  0.4954337
 [8,]  0.8257228
 [9,]  1.1560120
[10,]  1.4863011
attr(,"scaled:center")
[1] 5.5
attr(,"scaled:scale")
[1] 3.027650
> as.vector(y)
 [1] -1.4863011 -1.1560120 -0.8257228 -0.4954337 -0.1651446  0.1651446
 0.4954337  0.8257228  1.1560120
[10]  1.4863011

I think that the only way that you can accomplish this ``in a general  
way''
is to assign a new class (e.g. ``foo'') to the object returned by your
function and then write a new print method, print.foo(). Something like

print.foo <- function(x,...) {
attributes(x) <- NULL
print(x)
}
