Hello,
R 4.1.1 on Ubuntu 20.04.3 LTS.
I can reproduce this error. It happens with ggfortify 0.4.12 but not
with 0.4.11.
First ggfortify 0.4.11, notice the warnings.
rui@rui:~$ R -q -f rhelp.R
> library(ggfortify)
Loading required package: ggplot2
> library(cluster)
>
> autoplot(fanny(iris[-5], 3), frame = TRUE)

#---------------
Now ggfortify 0.4.12, notice that the errors are gone but there's a
message, probably printed with cat().

One problem was fixed, another showed up.
You should contact the package maintainer.
Hope this helps,

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 convex hulls., just as may be seen in the description of
ggfortify here:
http://rstudio-pubs-static.s3.amazonaws.com/53162_cd16ee63c24747459ccd180f69f07810.html
Presently, no hulls are drawn; instead some line is projected on each
cluster.
I found out that there is an addition to autoplot command, "frame.type =
c("convex", "norm", "t"). Whereas ""norm" and "t" give confidence
ellipses as expected, "convex" results in a straight line as mentioned
above.
Any help would be appreciated.
Best
