seq_qgrams: Get a table of qgram counts for integer sequences
Description
Get a table of qgram counts for integer sequences
Usage
seq_qgrams(..., .list = NULL, q = 1L)
Arguments
...
Any number of (named) arguments that will be coerced with as.integer
.list
Will be concatenated with the ... argument(s). Useful for adding integer vectors named 'q'.
q
The size of q-gramming.
Value
A matrix containing q-gram profiles. Columns 1 to q contain the
encountered q-grams. The ensuing (named) columns contain the q-gram counts
per vector. Run the example for a simple overview.
Missing values in integer sequences are treated as any other number.
