get_n.RdThis convenience function will return a named vector containing the number of cases flowing to or from a given region.
get_n(x, from = NULL, to = NULL, ...) # S3 method for epiflows get_n(x, from = NULL, to = NULL, ...)
| x | an epiflows object |
|---|---|
| from | a character vector of length one specifying the location from which the flows originate |
| to | a character vector of length one specifying the location to which the flows terminate |
| ... | unused |
a character vector
There are three possible outputs of this function:
no options specified: an un-named vector, equivalent to get_flows(x)$n
from = X: a named vector of cases flowing from X
to = X: a named vector of cases flowing to X
get_flows();
For location metadata: get_vars(), get_pop_size(), get_coordinates()
