[factoextra] is an R package making easy to extract and visualize the output of exploratory multivariate data analyses, including:. There are a number of R packages implementing principal component methods. These packages include: FactoMineR, ade4, stats, ca, MASS and ExPosition. However, the result is presented differently according to the used packages. To help in the interpretation and in the visualization of multivariate analysis - such as cluster analysis and dimensionality reduction analysis - we developed an easy-to-use R package named [factoextra] The figure below shows methods, which outputs can be visualized using the factoextra package.

Rotating labels within a dendrogram object and changing the default dendrogram colour (R)

Asked 2022-Mar-13 at 11:18

I am hoping to accomplish two things.

I want to be able to rotate the labels. The fviz_dend function is compatible with ggplot2 theme function but I am not entirely sure how to accomplish it.
I would like to change the line colour of the dendrogram - specifically those that do not fall within the clustering. I would like to change the black to white.

Any idea how to accomplish it on this reprex?

Answered 2022-Mar-13 at 11:18

From looking at the docs, I don't see a way to do this directly, but since this is a ggplot object, you can rewrite the layer data after creating the object.

ANSWER

Answered 2022-Mar-07 at 09:01

Since factoextra as a plotting library wraps ggplot2, we can use standard additional plot components to add the labels you want and change the legend.

First, make sure when plotting that you set label = "none" in fviz_pca_biplot() to ensure that the sample number isn't plotted next to the points.

Asked 2021-Dec-14 at 02:35

Does anyone know how to change the transparency(or alpha) of the color in the ellipse?
I want to remain only the line of boundary in the plot.
I tried to mimic the code in this site: http://www.sthda.com/english/wiki/fviz-pca-quick-principal-component-analysis-data-visualization-r-software-and-data-mining

How do I label only a subset of points in a biplot?

Asked 2021-Dec-02 at 05:16

I am generating biplots using fviz_pca_biplot in factoextra. The following code provides an example of my datset and the biplots. I'd like to label a subset of points, rather than all of them. For example, only species in a single genus like Eucalyptus. I can't figure out how, or even if it is possible. Can anyone suggest a solution?

ANSWER

Answered 2021-Dec-02 at 05:16

The object from fviz_pca_biplot() is a ggplot object. This means you can add to it with additional commands preceded by the +.

Using your data and starting from the res.pca object.
