Returns a randomly shuffled order of elements in the input data set.
NxShuffle(X, Seed, KeepNA)
- is the input data sample (one/two-dimensional array of cells (e.g. rows or columns)).
- 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.
- 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 result is always a 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 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.
