[njtierney]

Resolves issue in #192 - the code below now does not fail.

Curious on your thoughts, @MikeLydeamore

library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':

#>     filter, lag
#> The following objects are masked from 'package:base':

#>     intersect, setdiff, setequal, union
library(conmat)
contact_data <- get_polymod_contact_data("all") %>%
  filter(
    age_from <= 20,
    age_to <= 20
  )

population <- get_polymod_population() %>%
  filter(lower.age.limit <= 20)

m_all <- fit_single_contact_model(
  contact_data = contact_data,
  population = population
)

m_all_not_sym <- fit_single_contact_model(
  contact_data = contact_data,
  population = population,
  symmetrical = FALSE
)
