# rroad R package

Set of tools for monitoring road condition.

Currently, the following features are supported:

  - International Roughness Index (IRI) computation

    - continuously increasing segment

    - fixed length overlapping segments with an offset

## Download and Install

To download the development version of the package, type the following at the R command line:

```{r Install latest, eval=FALSE}

install.packages("devtools")

devtools::install_github("vsimko/rroad")

```

To download the release version of the package on CRAN, type the following at the R command line:

```{r Install from CRAN, eval=FALSE}

install.packages("rroad")

```

## Examples

```{r iri_from_random_profile, fig.width=8, fig.height=4}

profile <- rnorm(10000)

iri <- CalculateIRIperSegments(profile, IRI_COEF_100, 20)

par(mfrow = c(1,2)) # space for two diagrams

plot(profile, type = "l",

  xlab = "Distance [dm]", ylab = "Profile [mm]",

  main = "Read profile (Laser measurement)")

plot(iri, type = "s",

  xlab = "Segment", ylab = "IRI [m/km]",

  main = "International Roughness Index (IRI)\nsample = 10cm, segment = 20m")

```
