## Formatting and standardization checks on book chapters

### Description

Formatting and standardization checks on book chapters

### Usage

    checkVerbatim(files = .RbcBook1Files(ext=".tex"),
                   maxc = 70,
                  which = "both",
                verbose = TRUE)

    checkRnw(files = .RbcBook1Files(),
           verbose = TRUE, stopOnError=FALSE)

    checkPackage(files = .RbcBook1Files(ext=".Rnw"),
               verbose = TRUE)

    .RbcBook1Files(ext=".Rnw")

### Arguments

`files` | character vector with names (and path) of chapter source files
`ext` | character of length 1. File name extension. `.Rnw` (the default) and `.tex` should be the most important cases.
`maxc` | integer of length 1. Maximal number of characters in a verbatim line. All lines exceeding this limit will be reported in the return value of this function.
`which` | character of length 1. 'Sinput' will look at `Sinput` environments, 'Soutput' at `Soutput` environments, 'both' at both.
`verbose` | Logical.
`stopOnError` | Logical. If FALSE, first error found will lead to stop. If TRUE, try to continue checking.

### Details

`checkVerbatimLines` sees whether all verbatim lines have length at most `maxc`.

`checkPackage` finds all the occurences of Rpackage{...} in the text, checks whether the package is known, and returns a named list will all occurences of the packages.

### Value

For `checkVerbatimLines` and `checkSetup`, a data frame with one row for each offending line and various columns describing it.
For `.RbcBook1Files`, a character vector.

      checkVerbatim(files=f)
