# sctrip

The goal of sctrip is to reboot the trip package on a firmer basis. 

It's not very functional yet, but the goal is to create normal-form PATH objects that fit within a very general 

framework for structured data. PATHs aren't that useful in normal-form, but converting from external path-forms to PRIMITIVE forms and back is **very useful**.  More soon. 

## Installation

You can install sctrip from github with:

```{r gh-installation, eval = FALSE}

# install.packages("devtools")

devtools::install_github("mdsumner/sctrip")

```

## Example

Convert an existing trip object to a PATH and then a PRIMITIVE, composed of segments. 

```{r}

library(sctrip)

data("walrus818", package= "trip")

PRIMITIVE(walrus818)

```

Very much experimental, but here we work from raw data to create trips. A trip is a specialist and bespoke PATH, this will be turned inot tools that are much more general. 

```{r example}

library(sctrip)

apath <- sc_path(aurora, LONGITUDE_DEGEAST, LATITUDE_DEGNORTH, DATE_TIME_UTC)

```

The PATH object can be converted to PRIMITIVE form: 

```{r primitive}

sc::PRIMITIVE(apath)

```

We can do that no matter what choice we made when nominating the vertex columns. 

```{r flexible}

sc::PRIMITIVE(sc_path(aurora, DATE_TIME_UTC, LATITUDE_DEGNORTH))

```
