as.sparse: Convert between data frames and sparse matrices

In atakanekiz/Seurat3.0: Tools for Single Cell Genomics

Description

Convert between data frames and sparse matrices

Usage

as.sparse(x, ...)

## S3 method for class 'data.frame'
as.sparse(x, ...)

## S3 method for class 'Matrix'
as.data.frame(x, row.names = NULL, optional = FALSE,
  ..., stringsAsFactors = default.stringsAsFactors())

Arguments

x	An object
...	Arguments passed to other methods
row.names	NULL or a character vector giving the row names for the data frame. Missing values are not allowed.
optional	logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.
stringsAsFactors	logical: should the character vector be converted to a factor?

Value

as.sparse: A sparse representation of the input data

as.data.frame.Matrix: A data frame representation of the S4 Matrix
