read.series {limma} | R Documentation

## Read series of image files

### Description

Read in a series of array image analysis output files as data frames.

### Usage

    read.series(slides, path=NULL, suffix="spot", ...)

### Arguments

`slides` | character vector giving the names of files to be read in. Any suffix such as ".spot" or ".gpr" which is common to all the files can be omitted.
`path` | character string giving the directory containing the files. Can be omitted if the files are in the current working directory.
`suffix` | character string giving a suffix such as "spot" or "gpr" to be added to each file. If `NULL` then no suffix is added.
`...` | any other arguments to be passed to `read.table`

### Details

This function performs a series of calls to `read.table`. The image analysis output files are assumed to have been edited to remove all pre-heading material. The files are assumed to contain only column names and data. In most cases only can use `read.maimages` instead.

The data.frames produced by this command will typically be processed further using one of the functions `rg.spot`, `rg.genepix` or `rg.quantarray`.

### Value

No value is returned. However a series of data.frames are created on the current environment with names of the form filename.suffix. The files names are given by the elements of `slides` and the suffix is given by `suffix`.
