Format labels for S4 classes

Attempts to figure out appropriate labels for S4 classes.

S4LabelFormat(x, type = "major", ...)

# S4 method for ANY
S4LabelFormat(x, type = "major", ...)

# S4 method for WoodenHorse
S4LabelFormat(x, type = "major", ...)

# S4 method for ANYGenomic
S4LabelFormat(x, type = "major", ...)

Arguments

x	A vector to format
type	Either "major" or "minor" to determine how to format the labels (default: "major").
...	Optional arguments passed to downstream functions (not implemented).

Value

A character vector of the same length as x with labels

Details

The type argument is currently only implemented for the GenomicRanges class.

Examples

# Regular atomic vectors
S4LabelFormat(1:10)
#>  [1] "1"  "2"  "3"  "4"  "5"  "6"  "7"  "8"  "9"  "10"
S4LabelFormat(LETTERS[1:5])
#> [1] "A" "B" "C" "D" "E"

require(GenomicRanges)
# GenomicRanges major labels are seqnames
S4LabelFormat(GPos("chr1", 1:10))
#>  [1] "chr1" "chr1" "chr1" "chr1" "chr1" "chr1" "chr1" "chr1" "chr1" "chr1"

# GenomicRanges minor labels are positions formatted as basepairs
S4LabelFormat(GPos("chr1", 1:10), type = "minor")
#>  [1] "1 " "2 " "3 " "4 " "5 " "6 " "7 " "8 " "9 " "10"
