Re: [R] problem with plotting clustered data with convex hull using ggfortify

Dear Mr Barradas, thank you so much. After going back to the 4.1.1 version, the convex hulls were plotted again (R 4.1.0. Windows). Will forward all this to the package maintainer. But for the moment, your hint is of great help. Thank you, all my best Karl On 25.10.2021 00:32, Rui Barrada

ggfortify is a (nonstandard) contributed package. Please note that per the posting guide linked below: "For questions about functions in standard packages distributed with R (see the FAQ Add-on packages in R ), ask questions on R-

[R] problem with plotting clustered data with convex hull using ggfortify

Dear all: I have some data that I want to cluster and display as groups surrounded by convex hulls. Here, i use the iris data as an example: library(ggfortify) autoplot(fanny(iris[-5], 3), frame = TRUE) I used this code before, about a year ago, and then it resulted in data surrounded by con
