Most of the time, I will generate a pdf report, and I get beautiful graphics, thanks to the eps graphics device.

Finding Modes Using Kernel Density Estimates

TL; DR If you have a unimodal distribution of values, you can use R’s density or Scipy’s gaussian_kde to create density estimates of the data, and then take the maxima of the density estimate to get the mode. See below for actual examples in R and Python. Mode in R First, lets do this in R. Need some values to work with. library(ggplot2) set.seed(1234) n_point <- 1000 data_df <- data.
