The interlaced type extends vectors by adding a "missing reason" channel
which can be used to distinguish different types of missingness. The
interlaced() function constructs a new interlaced vector from a vector
or list of values.
Usage
interlaced(x, na = NULL)
as.interlaced(x, na = NULL, ...)
# Default S3 method
as.interlaced(x, na = NULL, ...)
# S3 method for class 'interlacer_interlaced'
as.interlaced(x, ...)
# S3 method for class 'data.frame'
as.interlaced(x, ...)
is.interlaced(x)
