median_is_determinate() tests whether a vector's median can be determined
despite missing values. It is based on median2().
Usage
median_is_determinate(x, na.rm.amount = 0)
Arguments
- x
Numeric or similar. Vector to search for its median.
- na.rm.amount
Numeric. Alternative to na.rm that only removes a
specified number of missing values. Default is 0.
Value
Logical (length 1).
Examples
# The median is 1, no matter which number
# `NA` represents:
median_is_determinate(c(1, 1, NA))
#> [1] FALSE
# Here, the median may be 1 or 2, depending
# on the value behind `NA`; so the median
# cannot be determined:
median_is_determinate(c(1, 2, NA))
#> [1] FALSE
