Source: R/trajectory-methods.R

Get the number of activities in a trajectory. length returns the number of first-level activities (sub-trajectories not included). get_n_activities returns the total number of activities (sub-trajectories included).

# S3 method for trajectory

Returns a non-negative integer of length 1.

Examples

x <- trajectory() %>%
  timeout(1)

x <- x %>%
  clone(2, x, x)
x
#> trajectory: anonymous, 4 activities
#> { Activity: Timeout      | delay: 1 }
#> { Activity: Clone        | n: 2 }
#>   Fork 1, continue,  trajectory: anonymous, 1 activities
#>   { Activity: Timeout      | delay: 1 }
#>   Fork 2, continue,  trajectory: anonymous, 1 activities
#>   { Activity: Timeout      | delay: 1 }

## length does not account for subtrajectories
length(x)
#> [1] 2
get_n_activities(x)
#> [1] 4
