I have two datasets that I would like to plot in a single figure. The first plot is generated by a function that then takes a subset of the data. (It is biological data so it is usually by chromosome e.g. function(data1,subset="chr8") ) Since not only are the chromosomes different sizes, but across different datasets there may be different numbers of points for a single chromosome, I do not know the coordinates on the x-axis prior to running the function.
I want the scale of the second plot to align to that of the first, but I don't know how to find the default xlim for the graph generated by the function. Is there any way to access this information so I can then pass it to the plot() of the second plot?
