scpdata.RdThe scpdata package distributes mass spectrometry-based
single-cell proteomics datasets. The datasets were collected from
published work and formatted to a standardized data framework.
The scp frameworks stores the expression data for different MS
levels (identified spectrum, peptide, or protein) in separate
assays. Each assay is an object of class SingleCellExperiment
that allows easy integration with state-of-the-art single-cell
analysis tools. All assays are contained in a single object of
class QFeatures. An overview of the data structure is shown
provided in the scp package.
The scpdata() function returns a summary table with all
currently available datasets in the package. More information
about the data content and the data collection can be found in the
corresponding manual pages.
scpdata()A DataFrame table containing a summary of the available
datasets.
More information about the data manipulation can be found
in the scp package.
