Recently I upgraded my linux server-deployed shiny app's R from 3.3.3 to 3.4.1, and now instead of cluster plots i'm getting this error.
Didn't change nothing else and can't access server to try and debug it. All I have now is an error message:
Warning: Error in clusplot.default: object 'spannel' not found
Stack trace (innermost first):

As far as I understand, spannel
is a C function, I know nothing about C, unfortunately.
here is briefly how it looks in server.R
file: clusplot(KMData, KM$cluster)
Any ideas?
