Replace observation support

Replace observation support

Usage

set_observations(dn, data = NULL, start = NULL, end = NULL)

Arguments

dn

A temporal network.

data

Optional data frame with start and end observation components. Overlapping and adjacent positive components are merged. Default NULL.

start, end

Optional scalar continuous bounds used instead of data, each defaulting to NULL. Supply exactly one of data or the start/end pair; supplying both, or neither, is an error.

Value

A new dynet object, class c("dynet", "netobject", "cograph_network"). Raw edge and vertex spells are unchanged – as.data.frame(x) still returns the originals – and only the non-destructive measurement view is replaced, so every verb now clips exposure and path horizons to this support. Read the components back with as.data.frame(x, what = "observations"), one row per component with observation, start, end, duration and instant. Raises dynet_bad_input when neither or both of data and the bounds are given.

Examples

dn <- dynet(school_contacts)
first_week <- set_observations(dn, start = 0, end = 7)
as.data.frame(first_week, what = "observations")
#>   observation start end duration instant
#> 1           1     0   7        7   FALSE
