R help - Jan 2011 - Question on ploting multiple series on the same plot

Thanks in advance for all help ,

I just started using R and have already done the following.

1. Read through multiple files to get input data
2. plot a vector (X say)
3. end


Now i want to plot the vector X for different files on the same plot, and I
don't know how to do that.
One option I considered was to have a global data frame that holds X for
each file.
and then plot after iterating  through the files.
However I found that X has different lengths for different input files.
Is there a cleaner way to do this

What you are proposing is a reasonable way of reading all the files
into a list object were each element is a separate file.  You can then
iterate through the list to determine the range for the plot.  If the
data is of different lenghts, then what are you plotting against?  Is
it just a single variable that you are plotting as a sequence, or is
there a set of X/Y values?  You can use xlim/ylim to setup the initial
plot.
