dia.bactgensize {seqinr} | R Documentation

## Distribution of bacterial genome size from GOLD

### Description

This function tries to download the last update of the GOLD (Genomes OnLine Database) to extract bacterial genomes sizes when available. The histogram and the default density() output is produced. Optionally, a maximum likelihood estimate of a superposition of two or three normal distributions is also represented

### Usage

    dia.bactgensize(fit = 2, p = 0.5, m1 = 2000, sd1 = 600, m2 = 4500,
           sd2 = 1000, p3 = 0.05, m3 = 9000, sd3 = 1000)

### Arguments

`fit` | integer value. If `fit == O` no normal fit is produced, if `fit == 2` try to fit a superposition of two normal distributions, if `fit == 3` try to fit a superposition of three normal distribution.
`p` | initial guess for the proportion of the first population.
`m1` | initial guess for the mean of the first population.
`sd1` | initial guess for the standard deviation of the first population.
`m2` | initial guess for the mean of the second population.
`sd2` | initial guess for the standard deviation of the second population.
`p3` | initial guess for the proportion of the third population.
`m3` | initial guess for the mean of the third population.
`sd3` | initial guess for the standard deviation of the second population.

### Value

An invisible dataframe with three components:

`comp1` | genus name
`comp2` | species names
`comp3` | genome size in Kb
