Coerce to data.frame.

as.data.frame(x, row.names = NULL, optional = FALSE, ...)

# S4 method for IPosRanges
as.data.frame(x, row.names = NULL,
  optional = FALSE, ...)

# S4 method for Matrix
as.data.frame(x, row.names = NULL, optional = FALSE,
  ...)

Arguments

x

any R object.

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.

...

additional arguments to be passed to or from methods.

Value

data.frame.
