Returns a randomly shuffled the order of elements in the input data set.
X is the input data sample (one/two dimensional array of cells (e.g. rows or columns)).
Seed is the seed value (positive integer) of the random number generator. If missing or zero(0), a random number from the CPU clock is used.
KeepNA is a flag for leaving (or purging) observations with missing values (e.g. #N/A, #VALUE!, #NUM!, empty cell) found in the input data set. If missing, keepNA=False.
- The input data set may span multiple rows and/or columns, but the results is always one-dimensional array (i.e. column).
- If the keepNA argument is set to False(0),observations with missing values (e.g. #N/A, #VALUE!, #NUM!, empty cell) in the input data set are purged prior to the shuffling.
- The returned array has the same size as the input data set minus the number of observations with missing values (e.g. #N/A, #VALUE!, etc.).
- For a seed value of zero(0), the NxShuffle will generate a random number from the machine clock , thus, returning a different ordered-elements set for each run.
- For negative seed value, NxShuffle returns #VALUE!
- The NxShuffle function is available starting with version 1.66 PARSON.
