Factor level attributes of interlaced vectors

The base S3 levels() function is overloaded for interlaced vectors, so when the value channel is a factor type, levels() will return its levels. Similarly na_levels() will return the levels for the missing reason channel.

Usage

# S3 method for class 'interlacer_interlaced'
levels(x)

na_levels(x)

Arguments

x

an interlaced vector

Value

The levels of the values or missing reason channel
