as_epidist() fails for infectious period from {epireview}

[joshwlambert]

Issue reported during Epiparameter workshop.

library(epiparameter)
library(epireview)

ebola <- epireview::load_epidata("ebola")
# lassa <- epireview::load_epidata("lassa")

param_name <- "Human delay - infectious period"

ebola$params %>%
  filter( parameter_type == param_name ) -> param_infectiousness

# Get value
param_infectiousness[6,]$parameter_value

# Convert to epidist and output available summary stats
epidist_admission_outcome <- epiparameter::as_epidist( param_infectiousness[6,] )

[joshwlambert]

The code chunk above also requires library(dyplr) for the filter() function.

The distribution type in the parameter entry from {epireview} being converted to an <epidist> object in this example is an exponential distribution which is currently unsupprted by <epidist>. See issue #328 for the feature request to rectify this.

[joshwlambert]

This issue is resolves as of PR #334. Here is a reproducible example using the fix and comparing the {epireview} data frame and the <epidist>.
