SubsetData: Return a subset of the Seurat object
In nukappa/seurat_v2: Seurat : R toolkit for single cell genomics

Description Usage Arguments Value

Creates a Seurat object containing only a subset of the cells in the original object. Takes either a list of cells to use as a subset, or a parameter (for example, a gene), to subset on.

SubsetData(object, cells.use = NULL, subset.name = NULL, ident.use = NULL,
  accept.low = -Inf, accept.high = Inf, do.center = F, do.scale = F,
  max.cells.per.ident = Inf, random.seed = 1, ...)

`object`	Seurat object
`cells.use`	A vector of cell names to use as a subset. If NULL (default), then this list will be computed based on the next three arguments. Otherwise, will return an object consissting only of these cells
`subset.name`	Parameter to subset on. Eg, the name of a gene, PC1, a column name in object@data.info, etc. Any argument that can be retreived using FetchData
`ident.use`	Create a cell subset based on the provided identity classes
`accept.low`	Low cutoff for the parameter (default is -Inf)
`accept.high`	High cutoff for the parameter (default is Inf)
`do.center`	Recenter the new object@scale.data
`do.scale`	Rescale the new object@scale.data. FALSE by default
`max.cells.per.ident`	Can be used to downsample the data to a certain max per cell ident. Default is inf.
`random.seed`	Random seed for downsampling
`...`	Additional arguments to be passed to FetchData (for example, use.imputed=TRUE)
