In TIMP: Fitting Separable Nonlinear Models in Spectroscopy and Microscopy

Description

Baseline subtraction from a vector, usually representing an IRF.

Usage

baseIRF(irfvec, indexlow, indexhigh, removeNeg = FALSE) 

Arguments

irfvec	Vector to subtract a baseline from
indexlow	Lowest index to base the baseline estimation on
indexhigh	Highest index to base the baseline estimation on
removeNeg	Whether negative values should be replaced with 0.

Details

Currently estimates the baseline as the mean of data between indexlow and indexhigh, and subtracts the result from the entire vector.

Value

vector

Examples

 
irfvec <- rnorm(128, mean=1) 
plot(irfvec,type="l") 
irfvec_corrected <- baseIRF(irfvec, 1, 10)
lines(irfvec_corrected, col=2)
