Computes the “unbiased” sample *L*-moments and *L*-moment
ratios of multiple sets of data stored in a list or matrix.
Following the paradigm of regional frequency analysis,
we regard the data sets as coming from different measurement sites.

`x` |
A list of numeric vectors, or a numeric matrix. |

`nmom` |

`sort.data` |
Logical: whether each data set should be sorted. |

`lcv` |
Logical.

Sample *L*-moments are computed for each data set.
The calculations use `samlmu`

internally.
If `x`

is a list, each list element should contain data for one site
and the names of the list elements should be the site names.
If `x`

is a matrix, each column should contain data for one site
and the column names should be the site names.

An object of class `regdata`

.
It is a data frame with columns `"name"`

and `"n"`

,
containing respectively the site names and the
number of non-missing data values at each site,
and further columns containing the *L*-moments and *L*-moment ratios,
in the order *l_1*, *t* (or *l_2*),
*t_3*, *t_4*, etc.

The default parameter values are chosen to be convenient
for the regional frequency analysis methods described by
Hosking and Wallis (1997).
Note that the number of *L*-moments and the choice
of whether to return *L*-CV or *L*-scale
are different from the defaults for `samlmu`

.
