Changing the x-axis in ggseqlogo in R

Question

[margo]

I have a sequence logo of 21 bases. I have generated a sequence logo using ggseqlogo and the x-axis goes from 1-21. I would like to be able to change the x-axis to read -10-+10. Does anyone know how to do this?

Untested but adding + scale_x_continuous(breaks=1:21, labels=-10:10) to the returned ggplot2 object should work.

Thank you! That works!
