Deciding what resolution to use can be a difficult question when approaching a clustering analysis. One way to approach this problem is to look at how samples move as the number of clusters increases. This package allows you to produce clustering trees, a visualisation for interrogating clusterings as resolution increases.
You can install the release version of clustree from CRAN with:
install.packages("clustree")If you want to use the development version that can be installed from
GitHub using the remotes package:
# install.packages("remotes")
remotes::install_github("lazappi/clustree@develop")To also build the vignettes use:
# install.packages("remotes")
remotes::install_github("lazappi/clustree@develop", dependencies = TRUE,
build_vignettes = TRUE)NOTE: Building the vignettes requires the installation of additional packages.
The documentation for clustree is available from CRAN at https://cran.r-project.org/package=clustree.
To view the vignette and all the package documentation for the development version visit http://lazappi.github.io/clustree.
