Cast to Sparse

# S3 method for class 'H5Group'
as.sparse(x, ...)

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

Arguments

x

An object

...

Arguments passed to other methods

row.names

NULL or a character vector giving the row names for the data; 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.data.frame.Matrix: A data frame representation of the S4 Matrix
