# R Package for Spatial Conformal Prediction

The goal of “scp” is to provide valid model-free spatial prediction

intervals.

## Installation

The current development version can be installed from source using

devtools.

``` r

devtools::install_github("mhuiying/scp", build_vignettes = TRUE)

```

## Example

``` r

library(scp)

# an example sample data

data('sample_data')

s  = sample_data$s

Y  = sample_data$Y

# locations to predict

s0  = c(0.5,0.5)

s0s = rbind(c(0.4, 0.4), c(0.5,0.5), c(0.6, 0.6))

# default prediction interval

scp(s0=s0,s=s,Y=Y)

scp(s0=s0s,s=s,Y=Y)

# user define eta=0.1, where LSCP is considered

scp(s0=s0,s=s,Y=Y,eta=0.1)

# user define non-conformity measure

scp(s0=s0,s=s,Y=Y,dfun="std_residual2")

# user define prediction function

fun = function(s0,s,Y) return(mean(Y))

scp(s0=s0,s=s,Y=Y,pred_fun=fun)

```

Want more example, please check our `vignettes`.

``` r

browseVignettes('scp')

```
