Vertical boxplot using chart.Boxplot

Question

I'm not able to get horizontal=FALSE in chart.Boxplot() to produce a vertical plot:

require(PerformanceAnalytics)
z <- runif(1:100)
chart.Boxplot(z)
chart.Boxplot(z, horizontal=FALSE)

The two plots look the same.

This is with PerformanceAnalytics version 1.1.0 and R version 3.0.0.

Answer 1

It is a small bug. You should contact the maintainer. You should just replace the line ( in 2 places in the code)

boxplot(R[, column.order], horizontal = TRUE,..

By

boxplot(R[, column.order], horizontal = horizontal,...
