pca.segments.2D(.data, .cast.freq.seg = T, ..., .do.plot = T)

Arguments

.data

Either data.frame or a list of data.frame or a result obtained from freq.segments or freq.segments.2D functions.

.cast.freq.seg

If T than case freq.segments or freq.segments.2D to the supplied data.

If T than plot a graphic, else return a pca object.

Value

• If .do.plot is T than ggplot object; else pca object.

data(twb)
# Plot a plot of results of PCA on V-segments usage.
