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

 The downloaded packages are in
        C:\Documents and Settings\Yuan\Local

 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?
