Description

Add scores to a plot

Usage

layer_scores(
  object,
  mapping = NULL,
  which = "PC1",
  key = "param",
  value = "value",
  scores_geom = list(ggplot2::geom_path(), ggplot2::geom_point()),
  sequential_facets = TRUE
)

plot_layer_scores(
  object,
  mapping,
  which = "PC1",
  key = "param",
  value = "value",
  ...
)

Arguments

object	A nested_prcomp or similar object
mapping	A mapping created with aes
which	Which principal components to plot
key	The column name to use for the principal component names
value	The column name to use for the principal component score values
scores_geom	One or more geometries to which scores should be applied.
sequential_facets	TRUE will result in the panel containing the dendrogram added to the right of the plot.
...	Passed to layer_scores()

Value

A list() that can be addeed to a ggplot2::ggplot()

Examples

library(ggplot2)
library(dplyr, warn.conflicts = FALSE)

alta_pca <- nested_data(
  alta_lake_geochem,
  qualifiers = c(age, depth, zone),
  key = param,
  value = value,
  trans = scale
) %>%
  nested_prcomp()

ggplot() +
  layer_scores(alta_pca, aes(value, depth), which = "PC1") +
  scale_y_reverse()

plot_layer_scores(alta_pca, aes(y = depth), which = c("PC1", "PC2")) +
  scale_y_reverse()
