proportions(x, margin = NULL) prop.table(x, margin = NULL)
x | a numeric matrix, a table, or an array. |
margin |
a vector of integers or character strings over which the margins are specified.
For example, if x is a matrix, margin=1 indicates rows
and margin=2 indicates columns.
If character strings, they are expected to be a subset of names(dimnames(x)).
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. |
