Major breaks for Vectors

Produces major breaks for use on plot axes.

S4BreaksMajor(x, n = 5L, ...)

# S4 method for numeric
S4BreaksMajor(x, n = 5L, ...)

# S4 method for GRanges
S4BreaksMajor(x, n = 5L, ...)

Arguments

x	A object describing the range of values
n	A desired number of breaks
...	Arguments passed to downstream functions

Value

A vector with major breaks positions

Details

The downstream function that arguments are typically passed to is the extended function, except when ranges are given as GenomicRanges.

Examples

# For simple numerics
S4BreaksMajor(c(0, 12))
#> [1]  0  3  6  9 12

# Gives GPos extremes for GRanges
require(GenomicRanges)
#> Loading required package: GenomicRanges
#> Loading required package: IRanges
#> Loading required package: GenomeInfoDb
S4BreaksMajor(GRanges(c("chr1:100-200", "chr2:140-260")))
#> <WoodenHorse: UnstitchedGPos[4]> 
#>  [1] chr1:100 chr1:200 chr2:140 chr2:260
