metacombine {DAPAR} | R Documentation

## Combine peptide metadata to build protein metadata

### Description

Agregation rules for the cells metadata of peptides. Please refer to the metacell vocabulary in 'metacell.def()'

# Basic agreagtion Agregation of non imputed values (2.X) with quantitative values (1.0, 1.X, 3.0, 3.X) |—————————- Not possible |—————————-

Agregation of different types of missing values (among 2.1, 2.2) |—————————- * Agregation of 2.1 peptides between each other gives a missing value non imputed (2.0) * Agreagtion of 2.2 peptides between each other givesa missing value non imputed (2.0) * Agregation of a mix of 2.1 and 2.2 gives a missing value non imputed (2.0) |—————————-

Agregation of a mix of quantitative values (among 1.0, 1.1, 1.2, 3.0, 3.X) |—————————- * if the type of all the peptides to agregate is 1.0, 1.1 or 1.2, then the final metadata is set the this tag * if the set of metacell to agregate is a mix of 1.0, 1.1 or 1.2, then the final metadata is set to 1.0 * if the set of metacell to agregate is a mix of 3.X and 3.0, then the final metadata is set to 3.0 * if the set of metacell to agregate is a mix of 3.X and 3.0 and other (X.X), then the final metadata is set to 4.0 |—————————-

# Post processing Update metacell with POV/MEC status for the categories 2.0 and 3.0 TODO

`level` | xxx

### Examples

    ## Not run:
    ll <- metacell.def('peptide')$node
    for (i in 1:length(ll))
    test <- lapply(combn(ll, i, simplify = FALSE),
    function(x) tag <- metacombine(x, 'peptide'))
