The Join command joins the specified data into a single one- or two-dimensional data sample.

The first parameter X is the list of samples; each element of this list must be an rtable (such as a Matrix or Vector ) or a list . Multi-dimensional data sets will generally be converted to one-dimensional. The exception is when each data set is two-dimensional and they all have equally many columns; in that case, all data sets are put underneath each other in a Matrix .

The options argument can contain one or more of the options shown be low.

outputoptions=list -- This option provides additional rtable_options to the rtable constructor that builds the result. The supported options are datatype, attributes, and readonly; the subtype option is supported if it does not conflict with the dimension of the result.
