## Check Package Vignettes

### Description

Check all `Sweave` files of a package by running `Sweave` and/or `Stangle` on them. All R source code files found after the tangling step are `source`ed to check whether all code can be executed without errors.

### Usage

    checkVignettes(package, dir, lib.loc = NULL,
                   tangle = TRUE, weave = TRUE, latex = FALSE,
                   workdir = c("tmp", "src", "cur"),
                   keepfiles = FALSE)

### Arguments

`package` | a character string naming an installed package. If given, Sweave files are searched in subdirectory ‘doc’.
`dir` | a character string specifying the path to a package's root source directory. This subdirectory ‘inst/doc’ is searched for Sweave files.
`lib.loc` | a character vector of directory names of R libraries, or `NULL`. The default value of `NULL` corresponds to all libraries currently known. The specified library trees are used to search for `package`.
`tangle` | Perform a tangle and `source` the extracted code?
`weave` | Perform a weave?
`latex` | logical: if `weave` and `latex` are `TRUE` and there is no ‘Makefile’ in the vignettes directory, run the weaved files through `pdflatex`.
`workdir` | Directory used as working directory while checking the vignettes. If `"tmp"` then a temporary directory is created, this is the default. If `"src"` then the directory containing the vignettes itself is used, if `"cur"` then the current working directory of R is used.

`keepfiles` | Delete files in the temporary directory? This option is ignored when `workdir != "tmp"`.

### Details

A ‘vignette’ is a file in the package's ‘inst/doc’ directory with extension ‘.Rnw’ (preferred), ‘.Snw’, ‘.Rtex’ or ‘.Stex’ (and lower-case versions are also accepted).

If `tangle` is true, this function runs `Stangle` to produce (one or more) R code files from each vignette, then `source`s each code file in turn.

If `weave` is true, the vignettes are run through `Sweave`, which will produce a ‘.tex’ file for each vignette. If `latex` is also true, `texi2pdf` is run on the ‘.tex’ files from those vignettes which did not give errors in the previous steps.

### Value

An object of class `"checkVignettes"`, which is a list with the error messages found during the tangle, source, weave and latex steps. There is a `print` method for displaying the information contained in such objects.
