R help - Nov 2010 - More detail in chart axis?

Hi,

I have a series of data (about 80,000 pairs of x,y).

Plotting it shows a great chart.  However, R has randomly chosen about 6
labels for my x axis.  Now, clearly I can't show them all, but would
like some control over the granularity of what is displayed.  I can't
find anything in the documentation about controlling the axis data
labels.  Is there a way?

Alternately, is there a package that would allow me to zoom into an area
of the chart so I can see more detail?

Thanks,

-N

Hi Noah,
"axis" will let you choose the positions, but may leave some out if it
thinks they are too close. "staxlab" (plotrix) allows you to specify 
positions and labels and can stagger or rotate the labels. zoomInPlot is 
only one way to show a section of the plot next to the original. 
zoomplot (TeachingDemos) allows you to zoom on the same plot. There are 
other functions that offer different zooming methods.
