Launch the dppca Shiny app — dppca

Launches an interactive Shiny application for exploring differentially private PCA visualizations. The app provides a graphical interface for dp_scree_plot() and dp_score_plot(), including private scree plot methods and histogram-based private score plot methods.

Usage

dppca_app(X = NULL, group = NULL)

Arguments

X: Optional numeric matrix or data frame. If supplied, the app opens with this data as the initial dataset.
group: Optional group labels. This can be either a vector of length nrow(X) or a single column name in X.

Value

No return value. This function opens a Shiny application.

Details

The app can be opened with built-in example datasets or with a user-supplied dataset. If X is supplied, the app starts with X as the initial dataset. If group is supplied, the score plot can use the group labels for coloring. The group argument can be either a vector of length nrow(X) or the name of a column in X. When group is a column name, that column is used as group labels and is removed from the PCA feature matrix.

Examples

if (interactive()) {
# Launch the app with built-in example datasets.
dppca_app()

# Launch the app with a user-supplied numeric dataset.
data(gau, package = "dppca")
dppca_app(gau)

# Launch the app with group labels stored in a column.
data(gau_g, package = "dppca")
dppca_app(gau_g, group = "group")
}
