plotConvergence.mnem {mnem} | R Documentation

## Plot convergence of EM

### Description

This function plots the convergence of the different EM iterations (four figures, e.g. par(mfrow=(2,2))).

### Usage

    ## S3 method for class 'mnem'
    plotConvergence(x, col = NULL, type = "b", convergence = 0.1, ...)

### Arguments

`x` | mnem object
`col` | vector of colors for the iterations
`type` | see ?plot.default
`convergence` | difference of when two log likelihoods are considered equal; see also convergence for the function mnem()
`...` | additional parameters for the plots/lines functions

### Value

plot of EM convergence

### Examples

    sim <- simData(Sgenes = 3, Egenes = 2, Nems = 2, mw = c(0.4,0.6))
    data <- (sim$data - 0.5)/0.5
    data <- data + rnorm(length(data), 0, 1)
    result <- mnem(data, k = 2, starts = 1)
    par(mfrow=c(2,2))
    plotConvergence(result)
