## Frequency table of the sequences

### Description

Computes the frequency table of the sequences (count and percent of each sequence).

### Usage

```
seqtab(seqdata, idxs = 1:10, weighted = TRUE, format = "SPS", tlim)
```

### Arguments

`seqdata` |
a sequence object as defined by the |

`idxs` |
returns the table for the sequences at ranks ' |

`weighted` |
if |

`format` |
format used for displaying the rownames (the sequences) in the output table.
Default is SPS format, which yields shorter and more readable sequence representations.
Alternatively, |

`tlim` |
Deprecated. Use |

### Details

The `weighted`

argument has no effect when no weights were assigned to the state sequence object since weights default in that case to 1.

### Value

An object of class `stslist.freq`

. This is actually a state sequence object (containing a list of state sequences) with added attributes, among others the `freq`

attribute containing the frequency table. There are `print`

and `plot`

methods for such objects. More sophisticated plots can be produced with the `seqplot`

function.

### Examples

```
## Creating a sequence object from the actcal data set
data(actcal)
actcal.lab <- c("> 37 hours", "19-36 hours", "1-18 hours", "no work")
actcal.seq <- seqdef(actcal, 13:24, labels=actcal.lab)
## 10 most frequent sequences in the data
seqtab(actcal.seq)
## With idxs=0, we get all distinct sequences in the data set
## sorted in decreasing order of their frequency
stab <- seqtab(actcal.seq, idxs=0)
head(stab)
tail(stab)
## Example with weights
## from biofam data set using weigths
data(ex1)
ex1.seq <- seqdef(ex1, 1:13, weights=ex1$weights)
## Unweighted frequencies
seqtab(ex1.seq, weighted=FALSE)
## Weighted frequencies
seqtab(ex1.seq, weighted=TRUE)
```
