Test/Check/Verify/Investigate the Ordering of Vectors

ordering provides several functions for testing/checking/verify/investigating the ordering of vectors (numeric or otherwise).

The packages has the following tests:

is_[strictly_]*

Where * can be one of:

In addition:

install

Install using the standard methods

install.packages('ordering')
 
# -OR-
 
devtools::install_github( "decisionpatterns/ordering")

Usage

The usage of the packages is probably best demonstrated by a few examples:

x <- 1:5

is_sorted(x)              # TRUE
is_strictly_sorted(x)     # TRUE

is_increasing(x)          # TRUE    
is_strictly_increasing(x) # TRUE

is_decreasing(x)          # FALSE
is_strictly_decreasing(x) # FALSE

is_sorted(x)              # TRUE
is_strictly_sorted(x)     # TRUE 

is_constant(x)            # FALSE
is_incremental()          # TRUE

monotonicity(x)           # 2 - strictly increasing
