## Installation

## Stable release from CRAN

`install.packages("wikilake")`

## Development version

`devtools::install_github("jsta/wikilake")`

## Usage

```{r example}

library(wikilake)

```

```{r metadata only, warning=FALSE}

# metadata only, see units of numeric fields with wikilake::unit_key_()

lake_wiki("Lake Mendota")

```

```{r }

# use the clean = FALSE argument to get raw data

# (i.e. avoid parsing of numeric fields)

lake_wiki("Lake Mendota", clean = FALSE)

```

```{r }

# pretty printing metadata

```

```{r echo = FALSE, message=FALSE}

knitr::kable(

  dplyr::left_join( 

    tidyr::pivot_longer(lake_wiki("Lake Mendota"), 

                      cols = tidyr::everything(),

                      values_to = "values_numeric",

                      values_transform = list(values_numeric = as.character)),

  tidyr::pivot_longer(lake_wiki("Lake Mendota", clean = FALSE), 

                      cols = tidyr::everything(),

                      values_to = "values_raw",

                      values_transform = list(values_raw = as.character)),

  

  by = "name"))

```

```{r worldmapping}

# metadata + map

lake_wiki("Gull Lake (Michigan)", map = TRUE)

```

```{r mapping}

lake_wiki("Gull Lake (Michigan)", map = TRUE, database = "usa")

```

```{r mapping2}

lake_wiki("Lake Nipigon", map = TRUE, regions = "Canada")
