I am working on r, but I found the following warning message:

stat_bin: binwidth defaulted to range/30. Use 'binwidth = x' to adjust this.

Is there any way to stabilize the issue “`stat_bin()` using `bins = 30`. pick better value with `binwidth`.”? I read a lot of topics about this, but all of them were trying to install anything. Is this the correct way, or any recommendation for me? Please find the beginning command below:

ggplot(data = iris, aes(x = Sepal.Length)) + stat_bin(bins = 5)
stat_bin()

  1. I have the same prolem with you and I tried this solution like this

    • Option 1
    ggplot(mpg, aes(x=T)) + geom_histogram(binwidth=1)

    • Option 2
    ggplot(mpg, aes(x=T)) + geom_histogram(binwidth=5)

  2. That’s sound interesting topic with the Error: `stat_bin()` using `bins = 30`. pick better value with `binwidth` Use this command line to run the result

    ggplot(mpg, aes(x=R)) + geom_histogram(binwidth=0.1)

    output:

  3. Follow this command and hope it work

    # Map values to a to flip the orientation
ggplot(diamonds, aes(a = carat)) +
geom_histogram()
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
