add_frag_info {spiky} | R Documentation

## decode fragment identifiers for spike-in standards

### Description

given a vector of fragment identifiers like `160_2_35` or `80b_1C_35G-2`, encoded typically as lengthInBp_numberOfCpGs_GCpercent, and optionally a database of spike-in sequences corresponding to those fragments, add those columns to the source data (along with, if present in the database, other metadata such as standard concentrations, GC fraction, etc.) and return i an updated DataFrame.

### Usage

    add_frag_info(x, frag_grp = "frag_grp", spike = NULL)

### Arguments

`x` | data.frame with a column of spike information (see above)
`frag_grp` | column name for the spike contig information (`frag_grp`)
`spike` | optional database of spike-in properties (none)

### Value

         the data.frame x, augmented with metadata columns

### Examples

    data(spike_cram_counts)
    data(spike, package="spiky")
    spike <- subset(spike, methylated == 1)
    add_frag_info(spike_cram_counts, spike=spike)
