Simplify likelihood levels

Collapse levels on a likelihood factor into smaller categories. For example "Likely improving" and "Very likely improving" are collapsed into a single level "Likely or very likely improving".

simplify_likelihood_levels(x)

Arguments

x

The vector with the likelihoods. Must be a factor or a character string

Value

A factor with simple categories

Examples

p <- seq(0, 1, length.out = 11)

get_likelihood_category(p) %>%
  order_likelihood_levels() %>%
  simplify_likelihood_levels()
#>  [1] Likely or very likely improving Likely or very likely improving
#>  [3] Likely or very likely improving Likely or very likely improving
#>  [5] Indeterminate                   Indeterminate                  
#>  [7] Indeterminate                   Likely or very likely worsening
#>  [9] Likely or very likely worsening Likely or very likely worsening
#> [11] Likely or very likely worsening
#> 3 Levels: Likely or very likely improving ... Likely or very likely worsening
