I have searched for this and can't believe I can't find it. Perhaps I've been asking the wrong question.
I have a set of data laid out in a histogram that has a xlim of $2,000,000. I am trying to set an interval of $100,000 for the breaks (rather than manually listing out every break with break = c(0, 50000, 100000, etc). How can I do this in ggplot? The breaks (ticks) are more important than the labels as I'll likely edit in Illustrator an abbreviated label (100k, etc)
p <- ggplot(mcsim, aes(result))
+ scale_x_continuous(formatter = "dollar")
+ geom_histogram(aes(y = (..count..)/sum(..count..))) + scale_y_continuous(formatter = 'percent')
Thanks!

To change the axis scales on a plot in base R Language, we can use the xlim() and ylim() functions. The xlim() and ylim() functions are convenience functions that set the limit of the x-axis and y-axis respectively.
Use scale_xx() functions It is also possible to use the functions scale_x_continuous() and scale_y_continuous() to change x and y axis limits, respectively.
Option 1. Set xaxt = "n" and yaxt = "n" to remove the tick labels of the plot and add the new labels with the axis function. Note that the at argument sets where to show the tick marks.
You can use breaks=seq(0, 2000000, by=100000). Effectively you are using seq to generate that vector you don't want to type out by hand.
