"as.data.frame"(x, row.names = NULL, optional = FALSE, ...)
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
base package as.data.frame()
methods use
optional
only for column names treatment, basically with the
meaning of data.frame(*, check.names = !optional)
.
