generateWeights {manta} | R Documentation

## Generate Weights

### Description

Because the manta plot uses integer count data, many of the points overlap and hide a large portion of the data. This function allows one to apply a weighting scheme to jitter points out from under each other both to show the density and expose the content of their pies (if applicable).

### Usage

    generateWeights(x, w.clmn,  agg.clmn, cond.clmn, ct.clmns=NULL)

### Arguments

`x` | an alignment dataframe
`w.clmn` | a string corresponding to a column with weight data
`agg.clmn` | a string corresponding to a column with an aggregation index.
`cond.clmn` | a string corresponding to a column with condition factor
`ct.clmns` | a string corresponding to a column with count data

### Value

a 2 by n weight matrix

    a <- read.delim(align.path, stringsAsFactors=FALSE)
    w <- generateWeights(a, 'what_e_value', 'what_def', 'treatment')
