prop.table(x, margin = NULL)
| x | a numeric matrix, a table, or an array. |
| margin |
a vector of subscripts over which the margins are specified.
For example, if x is a matrix, margin=1 indicates rows
and margin=2 indicates columns.
Note that margin specifies the dimensions by which the entries of x
are scaled in the result.
If margin is NULL, all entries in x are scaled by the sum of x. |
