[R] scatterplot to boxplot translation?

Thanks for the tip on "cut," seems like it should work. I must still be missing something, though. Here, I'm cutting on the y variable, then attempting the boxplot:
cutRPKM <- cut(count$RPKM, breaks=4)
 (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8]
Levels: (-0.0995,24.8] (24.8,49.8] (49.8,74.7] (74.7,99.6]
This gives me a single box instead of five boxes. ??
