intensity_PXD000022

This dataset has been collected during a study designed 
to compare the protein content of the exosome-like vesicles (ELVs) released 
from C2C12 murine myoblasts during proliferation (ELV-MB), and after 
differentiation into myotuves (ELV-MT). The dataset within this package 
contains proteins intensity processed using MaxQuant. More information 
can be found on ProteomeExchange public repository 
(http://proteomecentral.proteomexchange.org/cgi/GetDataset?ID=PXD000022) 
or in the original paper (see reference).

data

A collection of functions for left-censored missing data imputation. Left-censoring is a special case of missing not at random (MNAR)  mechanism that generates non-responses in proteomics experiments. The package also contains functions to artificially generate peptide/protein expression data (log-transformed) as random draws from a multivariate Gaussian distribution as well as a function to generate missing data (both randomly and non-randomly). For comparison reasons, the package also contains several wrapper functions for the imputation of non-responses that are missing at random. * New functionality has been added: a hybrid method that allows the imputation of missing values in a more complex scenario where the missing data are both MAR and MNAR.
