[R] error message when plotting survival curves

[stephen sefick]

I believe that you have to specify which variable is the x and also
the y.  I am not familiar with what you are doing, but it looks as
though you need to specify both x and y to get it to plot.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
