Dimensionality reduction through PCA

Description

Dimensionality reduction through PCA

Usage

dimred_pca(
  MAE,
  tax_level,
  color,
  shape = NULL,
  pcx = 1,
  pcy = 2,
  pcz = NULL,
  datatype = c("logcpm", "relabu", "counts")
)

Arguments

MAE	A multi-assay experiment object
tax_level	The taxon level used for organisms
color	A condition to color data points by e.g. "AGE"
shape	A condition to shape data points by e.g. "SEX"
pcx	Principal component on the x-axis e.g. 1
pcy	Principal component on the y-axis e.g. 2
pcz	Principal component on the z-axis e.g. 3
datatype	Datatype to use e.g. c("logcpm", "relabu", "counts")

Value

A list with a plotly object and summary table

Examples

data_dir <- system.file("extdata/MAE.rds", package = "animalcules")
toy_data <- readRDS(data_dir)
result <- dimred_pca(toy_data,
  tax_level = "genus",
  color = "AGE",
  shape = "DISEASE",
  pcx = 1,
  pcy = 2,
  datatype = "logcpm"
)
result$plot
result$table
