Details

If freq is set to FALSE, probability densities, component density, are plotted (so that the histogram has a total area of one). In this case, normal curve will not be generated.

Examples

# histogram(infert, age)
# histogram(infert, age, labels = FALSE)
# histogram(infert, age, freq = FALSE)

# }
