TICdata: TIC data.

In MRwarping: Multiresolution time warping for functional data.

Description

A sample of 11 curves with TIC counts of a Liquid Chromatography-Mass Spectrometry (LS-MS) data set.

Usage

data(TICdata)

Format

A data frame with 400 observations for each of 11 curves. The different rows correspond to the different curves.

## Preparation of the TIC data for use in warping.

# for smoothing the LC-MS data TIC
library("SemiPar")

index = 1:200*2-1
TICy = t(matrix(index,200,11))
TIC = as.matrix(TICdata)
x = 1:400
for (i in 1:11)
	{
	TIC.sm = spm(TIC[i,]~f(x))
	TICy[i,] = TIC.sm$fit$fitted[index]
	}
TICx = t(matrix(index,200,11))
