I am trying to visualize Agglomerative Hierarchical Clustering output in Dendrogram and got the following issue:
Warning message:
The <scale> argument of guides() cannot be FALSE. Use "none" instead as of
ggplot2 3.3.4.
ℹ The deprecated feature was likely used in the factoextra package.

Could someone explain what does it means and what is the solution to this?

Thanks for your help.
