## KCsmart

### Description

Multiple sample aCGH analysis using kernel convolution

### Details

Package: | KCsmart
Type: | Package
Version: | 1.0

License: | GPL

Use the wrapper function 'calcSpm' to calculate the sample point matrix. Use 'findSigLevelTrad' to find a significance threshold using permutation based testing. Use 'plot' to plot the sample point matrix or 'plotScaleSpace' to plot the significant regions over multiple scales (sigmas). Use 'getSigSegments' to retrieve the significantly gained and lost regions using specific cutoffs.

### Examples

    data(hsSampleData)
    data(hsMirrorLocs)

    spm1mb <- calcSpm(hsSampleData, hsMirrorLocs)
    spm4mb <- calcSpm(hsSampleData, hsMirrorLocs, sigma=4000000)

    plot(spm1mb)
    plot(spm1mb, chromosomes=c(1,5,6,'X'))

    siglevel1mb <- findSigLevelTrad(hsSampleData, spm1mb, n=3)
    siglevel4mb <- findSigLevelTrad(hsSampleData, spm4mb, n=3)

    plot(spm1mb, sig.level=siglevel1mb)

    plotScaleSpace(list(spm1mb, spm4mb), list(siglevel1mb, siglevel4mb), type='g')

    sigSegments1mb <- getSigSegments(spm1mb, siglevel1mb)
