Get a table of qgram counts for integer sequences
Get a table of qgram counts for integer sequences
seq_qgrams(..., .list = NULL, q = 1L)
... |
Any number of (named) arguments that will be coerced with |
.list |
Will be concatenated with the |
q |
The size of q-gramming. |
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.
# compare the 2-gram overlap between sequences 1:3 and 2:4 seq_qgrams(x = 1:3, y=2:4,q=2) # behavior when NA's are present. seq_qgrams(1:3,c(1,NA,2),NA_integer_)
