R: Example data sets with weighted and unweighted sequence data

ex2 {TraMineR} | R Documentation

## Example data sets with weighted and unweighted sequence data

### Description

Example data sets used to demonstrate the handling of weights. The `'ex2.weighted'` data set contains 6 sequences with weights inflating to 100 sequences (sum of weights is 100). The second data frame `'ex2.unweighted'` contains the corresponding 100 sequences.

The sequences are, in both data frames, in the `'seq'` column, and weights in the `'weight'` column of `'ex2.weighted'`.

The alphabet is made of four possible states: `A, B, C` and `D`.

These data sets are mainly intended to test and illustrate the handling of weights in TraMineR's functions. Weighted results obtained with '`ex2.weighted`' data set should be exactly the same as unweighted results obtained with the '`ex2.unweighted`' data set.

### Usage

    data(ex2)

### Format

The command `data(ex2)` generates two data frames:
`ex2.weighted`: a data frame with 6 rows, 1 variable containing sequences as character strings, 1 weight variable.
`ex2.unweighted`: a data frame with 100 rows, 1 variable containing sequences as character strings.

### Examples

    data(ex2)

    ex2w.seq <- seqdef(ex2.weighted, 1, weights=ex2.weighted$weight)
    ex2u.seq <- seqdef(ex2.unweighted)
