baseIRF

Baseline subtraction from a vector, usually representing an IRF.

Baseline subtraction from a vector, usually representing an IRF.

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

`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.

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