I am making frequency histograms using the histbackback function on my 2 
datasets. However when I try to use the brks function:

log(fie86),ylim=c(0,9),probability=FALSE,axes=TRUE,ylab=("log10 Parcel 

The graphic results in a 'NA' label for the y axis (no intervals are 

Also when I use 'summary(foo)' the break values are returned as follows:

  Length Class  Mode
left    9     -none- numeric
right   9     -none- numeric
breaks 1     -none- numeric

Can I manually add the y axis back in so there are values displayed?
