Initialize data.frame in a convenient way.

Initialize data.frame in a convenient way.

makeDataFrame(nrow, ncol, col.types, init, row.names = NULL,
  col.names = sprintf("V%i", seq_len(ncol)))

`nrow`	[`integer(1)`] Nubmer of rows.
`ncol`	[`integer(1)`] Number of columns.
`col.types`	[`character(ncol)` \| `character(1)`] Data types of columns. If you only pass one type, it will be replicated. Supported are all atomic modes also supported by `vector`, i.e. all common data frame types except factors.
`init`	[any] Scalar object to initialize all elements of the data.frame. You do not need to specify `col.types` if you pass this.
`row.names`	[`character` \| `integer` \| `NULL`] Row names. Default is `NULL`.
`col.names`	[`character` \| `integer`] Column names. Default is “V1”, “V2”, and so on.

print(makeDataFrame(3, 2, init = 7))
print(makeDataFrame(3, 2, "logical"))
print(makeDataFrame(3, 2, c("logical", "numeric")))
