Embeds cells in two dimensions using tSNE based on celda_CG results.

Embeds cells in two dimensions using tSNE based on celda_CG results.

# S3 method for celda_G
celdaTsne(counts, celda.mod, max.cells = 10000,
  modules = NULL, perplexity = 20, max.iter = 2500, seed = 12345, ...)

Arguments

counts	Integer matrix. Rows represent features and columns represent cells. This matrix should be the same as the one used to generate `celda.mod`.
celda.mod	Celda object of class "celda_G".
max.cells	Integer. Maximum number of cells to plot. Cells will be randomly subsampled if ncol(conts) > max.cells. Larger numbers of cells requires more memory. Default 10000.
modules	Integer vector. Determines which feature modules to use for tSNE. If NULL, all modules will be used. Default NULL.
perplexity	Numeric. Perplexity parameter for tSNE. Default 20.
max.iter	Integer. Maximum number of iterations in tSNE generation. Default 2500.
seed	Integer. Passed to set.seed(). Default 12345.
...	Additional parameters.

Examples

celda.sim = simulateCells("celda_G")
celda.mod = celda_G(celda.sim$counts, L=celda.sim$L)
