R-Change Number of Bins in Histogram, the default number of bins is determined by Sturges’ Rule. However, you can override this rule by specifying a specific number of bins using the breaks argument in the hist function. R-Change Number of Bins in Histogram For example, to create a histogram with 7 bins, you can use…
How to Specify Histogram Breaks in R, you may want to specify the number of breaks or bins to use. How to Specify Histogram Breaks in R By default, the hist() function uses Sturges’ Rule to determine the optimal number of bins based on the number of observations in the dataset. However, you can override…
