Simple problem in R

I found a package on www.bioconductor.com that allows me to install using
this line:

source("http://bioconductor.org/biocLite.R")
biocLite("MassSpecWavelet")

The prompt showed me the following message:

Running biocinstall version 2.1.10 with R version 2.6.2

updating HTML package descriptions

In their help package, they have listed commands that will allow a sample
runthrough of their algorithm using a sample dataset. 

I entered these codes in but was returned the following error messages:

data(exampleMS)
Warning message:
In data(exampleMS) : data set 'exampleMS' not found

SNR.Th <- 3
peakInfo <- peakDetectionCWT(exampleMS, SNR.Th=SNR.Th)

Error: could not find function "peakDetectionCWT"

majorPeakInfo = peakInfo$majorPeakInfo

Error: object "peakInfo" not found

peakIndex <- majorPeakInfo$peakIndex

Error: object "majorPeakInfo" not found

plotPeak(exampleMS, peakIndex, main=paste('Identified peaks with SNR >',
SNR.Th))

Did I make a mistake somewhere or is the code they wrote flawed?
