# sessioncheck

The primary goal of **sessioncheck** is to provide simple tools that can
be called at the top of a script, and produce warnings or errors if it
detects signs that the script is not being executed in a clean R
session. The intended user for **sessioncheck** is a beginner or
intermediate level R user who needs a drop-in replacement for the simple
but unsafe method of calling `rm(list = ls())` at the top of the script.
As a secondary goal, it also provides some reporting tools that can be
useful for describing the state of an R session.

## Installation

You can install the current CRAN release of sessioncheck with:

``` r

install.packages("sessioncheck")
```

Alternatively, you can install the development version of sessioncheck
from [GitHub](https://github.com/) with:

``` r

# install.packages("pak")
pak::pak("djnavarro/sessioncheck")
```

## Example

The intention when using **sessioncheck** is that you would rarely load
it with [`library()`](https://rdrr.io/r/base/library.html). Instead, a
single line of code like this would be added at the top of the script:

``` r

sessioncheck::sessioncheck()
```

The default behavior is to check for objects in the global environment
and to check packages and environments attached to the search path and
produce a warning if issues are detected. This can be converted to an
error if a stricter check is required, and additional checks can be
added if desired. For details on how the checks work and how they can be
customized see the [get
started](https://sessioncheck.djnavarro.net/articles/sessioncheck.html)
page.

In addition to providing tools to check the session state (most useful
at the start of a script), the package also supplies a
[`sessionstate()`](https://sessioncheck.djnavarro.net/reference/sessionstate.md)
function that reports the current state of a session (most useful at the
end of a script).

``` r

sessioncheck::sessionstate()
```
