head.dsm {wordspace} | R Documentation

## Return the Top Left Corner of a DSM Matrix (wordspace)

### Description

Returns the first `n` rows and first `k` columns of the co-occurrence matrix stored in a `dsm` object. If a scored matrix is available, it is automatically used; otherwise the raw frequencies are shown.

### Usage

    ## S3 method for class 'dsm'
    head(x, n = 6L, k = n, ...)

### Arguments

`x` | an object of class `dsm`
`n` | a single integer specifying the number of rows to extract
`k` | a single integer specifying the number of columns to extract (default: same as number of rows)
`...` | all other arguments are silently ignored

### Details

Note that in contrast to other `head` methods, negative values of `n` (and `k`) are not supported. There is also currently no corresponding `tail` method.

### Value

A dense or sparse co-occurrence matrix with `n` rows and `k` columns.
