The baytrends package was developed to enable users to evaluate long-term trends
in the Chesapeake Bay using a Generalized Additive Modeling (GAM) approach. The
model development includes selecting a GAM structure to describe nonlinear 
seasonally-varying changes over time, incorporation of hydrologic variability 
via either a river flow or salinity, the use of an intervention to deal with 
method or laboratory changes suspected to impact data values, and representation
of left- and interval-censored data. This approach, which is fully transferable
to other systems, allows for Chesapeake Bay water quality data to be evaluated 
in a statistically rigorous, yet flexible way to provide insights to a range of 
management- and research-focused questions.

## Installation

The CRAN version of baytrends from [CRAN](https://CRAN.R-project.org) 
can be installed with the code below.

``` r
install.packages("baytrends")
```

In some cases not all dependent packages are available on the user's system.
In these cases installing all dependencies is necessary.

```r
install.packages("baytrends", dependencies = TRUE)
```

The development version (with vignettes) from [GitHub](https://github.com/) 
can be installed with the code example below using the `remotes` package.

``` r
if(!require(remotes)){install.packages("remotes")}  #install if needed
install_github("tetratech/baytrends", force = TRUE, build_vignettes = TRUE)
```
