I need to auto scale the left y axis in the code below, so that when
I scroll left or right the left y-axis scale changes to accumulate the

also how can I make the crosshair horizontal since it is only
vertical

Dear R users.
is there an easy way to make R in ESS put out the line number of an error, or

in regards to the dynamic resizing, one would think that commands like
plot.default {package:graphics} does it, as I am exploring other
commands from graphics it seams like tkrplot may not be needed, I am
not sure as I just started with graphics in R, maybe a better way to
go is call TclTk from
