Get the limits of a the first two dimensions in a dimensionality reduction

When plotting an embedding, we may want to plot specific cells, but constrain the scale to match plots of the whole dataset. Given a dim. reduction, this function extracts the x and y limits to use for plotting.

drLims(seurat, reduction = "tsne")

Arguments

seurat	Seurat object for which a dimensionality reduction has been computed (e.g. PCA or tSNE)
reduction	String, corresponding to the dimensionality reduction to use. Default: "tsne".

Value

A list with two elements: "xlim", which is a character vector of the limits for the x-axis, and "ylim", correspondingly for the y-axis

Examples

drLims(pbmc)
#> $xlim
#> [1] -21.29039  19.81854
#> 
#> $ylim
#> [1] -55.72633  33.26469
