stacking x and y labels when graphing large amounts of data-R

Question

I am trying to graph a dataframe which is 1100x2 large. Because of the large amount of data, I find that ggplot stacks the labels. Is there a way to avoid this or just delete the labels altogether? Here is my graph:

and here is my code:

ggplot(data=`Rsa19766.01-s00-m01-1`, 
       aes(x=`Rsa19766.01-s00-m01-1`$Wavelength,
           y=`Rsa19766.01-s00-m01-1`$Reflection, 
           group=1,shape=".")) + 
  geom_line() + 
  ggtitle("Cary Ref")
