scImpute {PhosR} | R Documentation |
Impute the missing values for a phosphosite across replicates within a single condition (or treatment) if there are n or more quantified values of that phosphosite in that condition.
scImpute(mat, percent, grps)
mat |
a matrix with rows correspond to phosphosites and columns correspond to replicates within a condition. |
percent |
a percent from 0 to 1, specifying the percentage of quantified values in any treatment group. |
grps |
a string specifying the grouping (replciates). |
