data.table
Creates a data.table
that combines the transition probability matrices
and ID variables from a tparams_transprobs
object. This is often useful for
debugging.
## S3 method for class 'tparams_transprobs' as.data.table(x, ..., prefix = "prob_", sep = "_", long = FALSE)

Arguments passed to |
long |
If |
The output always contains columns for the ID variables and the
transition probabilities, but the form depends on on the long
argument.
If FALSE
, then a data.table
with one row for each transition probability
matrix is returned; otherwise, the data.table
contains one row for each
transition and columns from
(the state being transitioned from) and
to
(the state being transitioned to) are added.
