intervals (version 0.15.1)

close_intervals: Re-represent integer intervals with open or closed endpoints

Description

Given an integer interval matrix, adjust endpoints so that all intervals have the requested closure status.

Usage

# S4 method for Intervals_virtual
close_intervals(x)
# S4 method for Intervals_virtual
open_intervals(x)
# S4 method for Intervals
adjust_closure(x, close_left = TRUE, close_right = TRUE)
# S4 method for Intervals_full
adjust_closure(x, close_left = TRUE, close_right = TRUE)

Arguments

x

An object of appropriate class, and for which x@type == "Z". If x@type == "R", an error is generated.

close_left

Should the left endpoints be closed or open?

close_right

Should the right endpoints be closed or open?

Value

An object of the same class as x, with endpoints adjusted as necessary and all closed(x) set to either TRUE or FALSE, as appropriate.

Examples

# NOT RUN {
x <- Intervals(
               c( 1, 5, 10, 1, 6, 20 ),
               closed = c( TRUE, FALSE ),
               type = "Z"
               )

# Empties are dropped
close_intervals(x)
adjust_closure(x, FALSE, TRUE)

# Intervals_full
y <- as( x, "Intervals_full" )
closed(y)[1,2] <- TRUE
open_intervals(y)
# }
