Compute tSNE position of samples from a phyloseq object

Usage

tsne_pq(physeq, method = "bray", dims = 2, theta = 0, perplexity = 30, ...)

physeq: (required): a phyloseq-class object obtained using the phyloseq package.
method: A method to calculate distance using vegan::vegdist() function
dims: (Int) Output dimensionality (default: 2)
theta: (Numeric) Speed/accuracy trade-off (increase for less accuracy), set to 0.0 for exact TSNE (default: 0.0 see details in the man page of Rtsne::Rtsne).
perplexity: (Numeric) Perplexity parameter (should not be bigger than 3 * perplexity < nrow(X) - 1, see details in the man page of Rtsne::Rtsne)
...: Other arguments passed on to Rtsne::Rtsne()

A list of element including the matrix Y containing the new representations for the objects. See ?Rtsne::Rtsne() for more information
