This is a package in `R` to numerically calculate Fourier-type integrals
of univariate and bivariate functions with compact support and
simultaneously evaluated at several points. If the evaluation grid is
equally spaced, a Fast Fourier Transform method is used to speed up
computations.

See detailed documentation on the vignette (type
`browseVignettes("fourierin")` and then click “HTML”).

```

And the development version from [GitHub](https://github.com/) with:

``` r
# install.packages("devtools")
devtools::install_github("gbasulto/fourierin")
```

## Example

This is a basic example which shows you how to solve a common problem:

``` r
library(fourierin)
## basic example code
```
