as.data.frame S3 method for objects of class
# S3 method for crps as.data.frame(x, row.names = NULL, optional = FALSE, ...)
An object of class
NULL or a character vector giving the row
names for the data frame. Missing values are not allowed.
TRUE, setting row names and
converting column names (to syntactic names: see
make.names) is optional. Note that all of R's
as.data.frame() methods use
optional only for column names treatment, basically with the
data.frame(*, check.names = !optional).
See also the
make.names argument of the
additional arguments to be passed to or from methods.
