image {oligo} | R Documentation

## Display a pseudo-image of a microarray chip

### Description

Produces a pseudo-image (`graphics::image`) for each sample.

### Usage

    ## S4 method for signature 'FeatureSet'
    image(x, which, transfo=log2, ...)

    ## S4 method for signature 'PLMset'
    image(x, which=0,
                       type=c("weights","resids", "pos.resids","neg.resids","sign.resids"),
                       use.log=TRUE, add.legend=FALSE, standardize=FALSE,
                       col=NULL, main, ...)

### Arguments

`x` | `FeatureSet` object
`which` | integer indices of samples to be plotted (optional).
`transfo` | function to be applied to the data prior to plotting.
`type` | Type of statistics to be used.
`use.log` | Use log.
`add.legend` | Add legend.
`standardize` | Standardize residuals.
`col` | Colors to be used.
`main` | Main title.
`...` | parameters to be passed to `image`

### Examples

    if(require(oligoData) & require(pd.hg18.60mer.expr)){
      data(nimbleExpressionFS)
      par(mfrow=c(1, 2))
      image(nimbleExpressionFS, which=4)
    ##  fit <- fitPLM(nimbleExpressionFS)
    ##  image(fit, which=4)
      plot(1) ## while fixing fitPLM TODO
    }
