It's mean that x axis has to be ordered like: Genotype 2, Genotype 3, Genotype 1. The actual binning is done using hist. The basic syntax to create a boxplot in R is − boxplot (x, data, notch, varwidth, names, main) Following is the description of the parameters used − x is a vector or a formula. values in x are assigned to the bins defined by breaks. The position vectors will be recycled to the length of the longest. Calculate the cumulative sum of len for each dose category. However, the boxes do not always appear in the order you would prefer. Small multiple. This function draws a box around the current plot in the given color and linetype. The summary statistics used to create a box and whisker plot are the median of the data, the lower and upper quartiles (25% and 75%) and the minimum and maximum values. A barchart can look pretty good using a circular layout, even if there are some caveats associated.
