## Installation

You can install the **released** version of `spfda` ![CRAN-version](https://www.r-pkg.org/badges/version/spfda) from [CRAN](https://CRAN.R-project.org/package=spfda) with:

``` r

install.packages("spfda")

```

The **experimental** version can be installed via

``` r

# install.packages("remotes")

remotes::install_github("dipterix/spfda")

```

## Example

``` r

library(spfda)

dat <- spfda_simulate()

x <- dat$X

y <- dat$Y

## basic example code

fit <- spfda(y, x, lambda = 5, CI = TRUE)

## Generics

BIC(fit)

plot(fit, col = c("orange", "dodgerblue3", "darkgreen"),

     main = "Fitted with 95% CI", aty = c(0, 0.5, 1), atx = c(0,0.2,0.8,1))

matpoints(fit$time, t(dat$env$beta), type = 'l', col = 'black', lty = 2)

legend('topleft', c("Fitted", "Underlying"), lty = c(1,2), bty = 'n')

print(fit)

coefficients(fit)

```
