The **eemR** package implements various functions used calculate metrics from excitation-emission matrix (EEM) as well as to preform pre-processing corrections before PARAFAC analysis.

The latest release of the package from CRAN can be installed with:

```{r, eval = FALSE}

install.packages("eemR")

```

The latest development version of the package can be installed with:

```{r install, eval = FALSE}

devtools::install_github("PMassicotte/eemR")

```

## Vignette

A detailed vignette presenting the package which can be viewed using:

```{r, eval = FALSE}

vignette(topic = "introduction", package = "eemR")

```

## Supported spectrophotometers

At the moment, EEMs generated by the following spectrofluorometer are officially supported.

- Cary Eclipse `.csv` files

- Aqualog `.dat` files

- Shimadzu `.TXT` files

- Fluoromax-4 `.dat` files

- Hitachi F-7000 FL `.TXT` files

EEM can be read using the `eem_read()` function. Please fill an [issue](https://github.com/PMassicotte/eemR/issues) if you have other file formats you would like to add to the package. You can also write your own [import function](http://pmassicotte.github.io/eemR/articles/custom-import-function.html)!
