How to deal with warning message `stat_bin()` using `bins = 30`. Pick better value with `binwidth`. in R while creating a histogram?

The default value for bins is 30 but if we don’t pass that in geom_histogram then the warning message is shown by R in most of the cases. To avoid that, we can simply put bins=30 inside the geom_histogram() function. This will stop showing the warning message.

Consider the below data frame −

x<-rnorm(50000,5,1)
df<-data.frame(x)

Loading ggplot2 package and creating histogram of x −

Example

library(ggplot2) ggplot(df,aes(x))+geom_histogram() `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

Output

Creating the histogram by specifying the bins −

Example

ggplot(df,aes(x))+geom_histogram(bins=30)

Output
