Custom x-scale - separate scale_x_logo from geom_logo?

[ewallace]

It would be wonderful to be able to pass in custom x-axis labels. For example, if I am making a consensus sequence around a start codon, we want the "A" of "ATG" to be position 1.

Currently this is challenging in ggseqlogo because geom_logo includes a scale function, which is inconsistent with ggplot2's separation of concerns. I don't think that it is necessary, as in my hands that scale argument does not change the resulting plot.

Could we remove scale from geom_logo, and then if necessary create a scale_logo function with start position as an argument?

I would also appreciate the possibility of manipulating the x-axis scale. It is probably already known, but this work-around works:

fig<-ggplot() + geom_logo(data)
fig$scales$scales[[1]] <- scale_x_continuous(breaks= seq(2,10,by=2),labels=c("A", "B", "C", "D", "E"))

with some reservation for how to construct the scale in any particular case.
