In chr1swallace/GUESSFM: Using GUESS for Fine Mapping

Description

internal function: xscale

Usage

xscale(x, torange, xrange = c(min(x), max(x)))

Arguments

x	numeric vector to be transformed
torange	new range
xrange	optional. full range of x vector if you are scaling only part of it. calculated from x if not supplied.

Details

Linear transformation to map x to a new range, so min(x)==xrange[1], and max(x)==xrange[2]

Value

transformed numeric vector

Examples

x<-1:10
cbind(x,
      GUESSFM:::xscale(x,c(0.1,1)),
      GUESSFM:::xscale(x,c(1319,20578)))
## Now use only part of x
x<-x[2:7]
## WRONG
cbind(x,
      GUESSFM:::xscale(x,c(0.1,1)),
      GUESSFM:::xscale(x,c(1319,20578)))
## RIGHT
cbind(x,
      GUESSFM:::xscale(x,c(0.1,1),xrange=c(1,10)),
      GUESSFM:::xscale(x,c(1319,20578),xrange=c(1,10)))
