statistics - how to use a log scale for y-axis of histogram in R?

问题描述:

I have a large dataset with the lifespan of threads on an discussion board. I want a histogram that shows the distribution of lifespan, so I did this:

dall <- read.csv("lifespan.csv")

colnames(dall) <- c("thread.id", "seconds.alive", "start.time")

hist(dall$seconds.alive)

which generated this hard to read image:

My questions are

a) is changing y-axis to a log-scale a good way to make it more readable? Apparently some people think is a bad idea to change y-axis to log.

b) how do I do that?

网友答案:

I would try using hist(log10(dall$seconds.alive)) instead.

Also try specifying breaks=100 or smaller/larger number:

hist(log10(dall$seconds.alive), breaks=100)
