## Output Functionalities.

### Description

`write_primers`

  Writes a set of primers to disk, either as a FASTA or CSV file.

`write_settings`

  Stores primer analysis settings to a file in XML format.

`write_templates`

  Stores a set of templates as a FASTA or CSV file.

`create_report`

  Creates a PDF report for analyzed primer sets.

`create_coverage_xls`

  Creation of an XLS spreadsheet providing an overview of the covered template sequences for each primer. Each cell in the spreadsheet indicates a coverage event between a primer and template using color codes. Identified coverage events are indicated by green, while primer-template pairs without coverage are indicated by red. In case that a primer binding condition (see `CoverageConstraints`) was active when computing the coverage, the numeric value of the coverage condition is annotated for each cell.

### Usage

    write_templates(template.df, fname, ftype = c("FASTA", "CSV"))

    write_primers(primer.df, fname, ftype = c("FASTA", "CSV"))

    create_coverage_xls(primer.df, template.df, fname, settings)

    create_report(primers, templates, fname, settings, sample.name = NULL,
      used.settings = NULL, ...)

    write_settings(settings, fname)

### Arguments

`template.df` | An object of class `Templates`.
`fname` | The path to the output file.
`ftype` | A character vector giving the type of the file. This can either be "FASTA" or "CSV" (default: "FASTA").
`primer.df` | An object of class `Primers`.
`settings` | A `DesignSettings` object to be stored to disk.
`primers` | To create a report for a single primer set, please provide an evaluated `Primers` object. For creating a report comparing multiple primer sets, please provide a list of `Primers` objects.
`templates` | If `primers` is a `Primers` object, `templates` should be a `Templates` object. If `primers` is a list of `Primers` objects, `templates` should be a list of `Templates` objects of the same length as `primers`.
`sample.name` | An identifier for your analysis. By default ( `NULL`), the sample identifier is selected from the `Run` column of the input templates.
`used.settings` | A named list (with fields `fw` and `rev`) containing the relaxed settings for designing forward/reverse primers. By default (`NULL`), the relaxed settings are not shown in the report.
`...` | `required.cvg` (optional, default: 1), the desired coverage ratio if `primers` is a single primer set.

### Value

`write_templates` stores templates to `fname`.

`write_primers` stores primers to disk.

`create_coverage_xls` stores information on the primer coverage in a spreadsheet.

`create_report` Creates a PDF file summarizing the results from analyzing one or multiple sets of primers.

`write_settings` returns the status from closing the connection to the output file.

### Note

Creating the report requires the external programs Pandoc (http://pandoc.org) and LaTeX (http://latex-project.org).
