R help - Oct 2005 - apply and plot

R-help,

I use the code below to plot some data by applying "apply" function.
But I don't know how I can get the argument "type" or
"col" on the
"plot" function to distinguish the different lines
in the graph:

apply ( my.data, 2, function ( x ) lines ( dimnames ( my.data ) [[1]] ,
x ) )


Thank you in advance

Rather than trying the use the construct above, take a look at ?matlines
and/or ?matplot (both on the same help page with ?matpoints.)

I think that you will find these purposefully designed functions better
suited to what I believe you are trying to do here.
