createSparseMat R Documentation
Creates a sparse matrix from a list of 'MassPeaks' objects
Description
The sparse matrix is created via 'Matrix::sparseMatrix'. This type
of representation speeds-up computation compared to 'MALDIquant::MassPeaks'.
Usage
createSparseMat(x)
Arguments
x:
a list of MassPeaks objects.
Value
An S3 class 'sparseIntensityMatrix' with three slots; 'spmat' - sparse matrix
of type 'Matrix::dgCMatrix' holding the spectral intensities (see ?Matrix::sparseMatrix),
'mzAxis' - a numeric holding all m/z bins (in Da) and, finally, 'coordinates' - a two-column matrix
holding the coordinates of the spectra which are stored in rows of 'spmat'.
