So, if one has the great idea to set border = "white" then the whiskers are also going to “disappear” and you have a white line representing your median. Just to explore the data further, I tried plotting the TotalVisits values in a box plot. The plot doesn't seem to have a lower whisker. q1=1 and there are no values between q1 and q1-1.5(IQR). The plot has q1, q2 and q3. The minimum value and q1 are the same. Is this why the boxplot doesn't have the lower whisker?

In R’s default boxplot {graphics} code, upper whisker = min (max (x), Q_3 + 1.5 * IQR) lower whisker = max (min (x), Q_1 – 1.5 * IQR) where IQR = Q_3 – Q_1, the box length. So the upper whisker is located at the *smaller* of the maximum x value and Q_3 + 1.5 IQR, corr1 = corr [c (1:5, 8:9),1:4] # to remove NAs # to order the cournties the way I need Country1 = factor (corr1$Country, levels (corr1$Country) [c (1,9,6,5,3,8,7)]) x = c (1,2,3,4,5,6,7,8,9) plot (Country1, corr1$Mean, pch=19, ylim=range (c (corr1$Mean-corr1$Min, corr1$Mean+corr1$Min))) # hack: we draw arrows but with very special "arrowheads" In the geom_boxplot documentation it says that this argument determines the "length of the whiskers as multiple of IQR. Defaults to 1.5", so probably I tried 0.

Description Usage Arguments Aesthetics Examples. View source: R/geom- boxploth.R  In this recipe, we will see how to make box plots with horizontal boxes instead of the default vertical ones. Box plots can be created for individual variables or for variables by group. The syntax is boxplot(x, data=), where x is a formula and data denotes the data frame   In descriptive statistics, a box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles.
