eigen_pi R Documentation
Compute PI - proportion of observations missing completely at random
Description
Compute PI - proportion of observations missing completely at random
Usage
eigen_pi(m, toplot = TRUE)
Arguments
m
matrix of abundances, numsmaples x numpeptides
toplot
TRUE/FALSE plot mean vs protportion missing curve and PI
Value
pi estimate of the proportion of
observations missing completely at random
Contributed by Shelley Herbrich & Tom Taverner for Karpievitch et al. 2009
Examples
data(mm_peptides)
intsCols = 8:13
metaCols = 1:7
m_logInts = make_intencities(mm_peptides, intsCols)
m_prot.info = make_meta(mm_peptides, metaCols)
m_logInts = convert_log2(m_logInts)
my.pi = eigen_pi(m_logInts, toplot=TRUE)
