Description Usage Arguments Value Note Examples
Plotting for Subspace clusterings as generated by the package subspace.
Generates a 2d-scatterplot with interactive controls to select the dimensions that should be plotted.
This visualization is created using the ggvis package and is therefore also compatible with shiny.

x |
an S3-Object of type subspace_clustering as generated by any of the functions of the subspace package |
data |
The original data matrix on which the clustering was performed. |
color_by |
a parameter indicating how a point that is in multiple clusters should be colored. If "mix" is selected, the point will be colored as a mixture of the colors of both of the clusters that the point is in. If "any" is selected, a random color is selected from the colors of all the clusters that the point is in. |
standardcolors |
a vector of strings representing HTML-Colors that will be used to color the points by cluster assignment. Noise will be colored with the last color in the vector. |
tooltip_on |
decides if tooltips should be shown on "hover" or on "click" |
... |
this is passed on to ggvis::layer_points and can be used to change, for example the size of the points |
a ggvis object. If the return value is not used, a plot will be shown, but the returned plot can also be altered using ggvis
When passing ellipsis parameters, the ":=" syntax from ggvis may get in your way, but you can work around this by manually creating a props object as seen in the example.
