ca_3Dplot: Plot of the first 3D CA projection of the data.

In VingronLab/APL: Association Plots

Plot of the first 3D CA projection of the data.

Description

Plots the first 3 dimensions of the rows and columns in the same plot.

Usage

ca_3Dplot(
  obj,
  xdim = 1,
  ydim = 2,
  zdim = 3,
  princ_coords = 1,
  row_labels = NULL,
  col_labels = NULL,
  ...
)

## S4 method for signature 'cacomp'
ca_3Dplot(
  obj,
  xdim = 1,
  ydim = 2,
  zdim = 3,
  princ_coords = 1,
  row_labels = NULL,
  col_labels = NULL,
  ...
)

## S4 method for signature 'Seurat'
ca_3Dplot(
  obj,
  xdim = 1,
  ydim = 2,
  zdim = 3,
  princ_coords = 1,
  row_labels = NULL,
  col_labels = NULL,
  ...,
  assay = Seurat::DefaultAssay(obj),
  slot = "counts"
)

## S4 method for signature 'SingleCellExperiment'
ca_3Dplot(
  obj,
  xdim = 1,
  ydim = 2,
  zdim = 3,
  princ_coords = 1,
  row_labels = NULL,
  col_labels = NULL,
  ...,
  assay = "counts"
)

Arguments

obj	An object of class "cacomp", or alternatively an object of class "Seurat" or "SingleCellExperiment" with a dim. reduction named "CA" saved.
xdim	Integer. The dimension for the x-axis. Default 1.
ydim	Integer. The dimension for the y-axis. Default 2.
zdim	Integer. The dimension for the z-axis. Default 3.
princ_coords	Integer. If 1 then principal coordinates are used for the rows, if 2 for the columns. Default 1 (rows).
row_labels	Numeric vector. Indices for the rows for which a label should be added (label should be stored in rownames). Default NULL.
col_labels	Numeric vector. Indices for the columns for which a label should be added (label should be stored in colnames). Default NULL (no columns).
...	Further arguments.
assay	SingleCellExperiment assay to obtain counts from.
slot	Seurat slot from assay to get count matrix from.

Details

Depending on whether 'princ_coords' is set to 1 or 2 either the principal coordinates of either the rows (1) or the columns (2) are chosen. For the other the standardized coordinates are plotted (assymetric biplot). Labels for rows and columns should be stored in the row- and column names respectively.

Value

Plot of class "plotly".

Examples

# Simulate counts
cnts <- mapply(function(x){rpois(n = 500, lambda = x)},
               x = sample(1:100, 50, replace = TRUE))
rownames(cnts) <- paste0("gene_", 1:nrow(cnts))
colnames(cnts) <- paste0("cell_", 1:ncol(cnts))

# Run correspondence analysis
ca <- cacomp(obj = cnts, princ_coords = 3)

ca_3Dplot(ca)
