The number elements to generate. This can be globally set within
the environment of r_data_frame

.
logical. If TRUE

A vector of elements to chose from. This may be NULL
if
arguments are supplied to start
, k
, and by
. The
x
argument takes precedence over the other three if !is.null
.
Note that start
, k
, and by
work together to make a
vector of dates to sample from. See seq.Date
for
additional information.
A date to start the sequence at.
The length of the sequence (number of the elements) so build out from
start
.
The interval to use in building the sequence.
A vector of probabilities to chose from.
The name to assign to the output vector's varname
attribute. This is used to auto assign names to the column/vector name when

.
