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
