Histogram with Logarithmic Scale and custom breaks

Question

I\'m trying to generate a histogram in R with a logarithmic scale for y. Currently I do:

hist(mydata$V3, breaks=c(0,1,2,3,4,5,25))

This giv

Answer 1

Run the hist() function without making a graph, log-transform the counts, and then draw the figure.

hist.data = hist(my.data, plot=F)
hist.data$counts = log(hist.data$counts, 2)
plot(hist.data)

It should look just like the regular histogram, but the y-axis will be log2 Frequency.
