[R] Label Rotation when Plotting with Factors

Sorry if this is a repeat, having trouble finding what I need on archive and am a novice with graphics in R!

I have plotted the results of a logit regression by factor, where "city" is the factor set name. The problem is city names are too long and I need to rotate them 90 degrees along the xaxis. This is what I've tried...

plot(city, predicted.probability, xlab = "city"...) axis(1,las = 2)

This does not affect the existing labels.

I have also tried (axes=FALSE), and then rename new with (labels = "Denver", etc. ), but it seems as though I need to maintain the factor identities, as it give me the error: 'labels' is supplied and not 'at'

Any suggestions?

Thank you,

marion wittmann
