tImpute {PhosR} | R Documentation |
Tail-based imputation approach as implemented in Perseus.
tImpute(mat, m, s)
mat |
a matrix with rows correspond to phosphosites and columns correspond to samples. |
m |
a numeric number for controlling mean downshifting. |
s |
a numeric number for controlling standard deviation of downshifted sampling values. |
An imputed matrix
