r – ggplot2 legend not appearing

The @benson23 answer is correct, if you want more control you can use manual scales for different aesthetics. If you use linetype in aes instead of fill, you will get a legend as above, if you like that more. library(tidyverse) df <- tribble( ~ tree, ~ o18, “A”, 15, “A”,…

r – How to fit “Negative Binomial” Distribution on a histogram using ggplot2()?

I am working with a dataset that I believe follows a “Negative Binomial” distribution. However, when I fit the Negative Binomial distribution, it turns out to be a poor fit. To explore further, I simulated a Negative Binomial distribution, but even on the simulated data, the overlaying distribution does not…

r – ggplot plots in scripts do not display in Rstudio

The solution is to explicitly call print() on ggplot object: library(ggplot2) p <- ggplot(mtcars, aes(wt, mpg)) p <- p + geom_point() print(p) ggplot function returns object of class ggplot; ggplot2 works by overloading print function to behave differently on objects of class ggplot – instead of printing them to STDOUT,…
