transformTo: Transform coordinate system.

In jotsetung/GenomePlotR: Plotting data in genomic context

Description

Transforms (linear) coordinates from one coordinate system (defined by its range) into an other coordinate system (defined by its range).

Usage

transformTo(x, old.range = range(x), new.range)

Arguments

x	Coordinates in the old coordinate system that should be transformed.
old.range	The range (minimal and maximal value) of the old coordinate system.
new.range	The range of the coordinate system into which the values in x should be transformed.

Value

The values in x transformed into the new coordinate system.

Examples

# transform x into a coordinate system ranging from 10 to 100.
# in this simple exampl the 1 is mapped to 10 and 8 to 100
x <- c( 1, 4, 2, 8 )
transformTo( x, new.range=c( 10, 100 ) )

y <- c( 1, 5, 10, 4 )

x-y
transformTo( x, old.range=range( c( x, y ) ), new.range=c( 10, 100 ) )

transformTo( x, old.range=range( c( x, y ) ), new.range=c( 10, 100 ) ) - transformTo( y, old.range=range( c( x, y ) ), new.range=c( 10, 100 ) )
