# useful

This package is for helper functions I end up using all the time.

Its under heavy development at the moment - so probably best to chat to me if you want to use anything.

Things in this package are for:

-   Plotting temperature and precipitation response functions from `fixest` regression output

## Installation

You can install the development version of useful from [GitHub](https://github.com/) with:

``` r
# install.packages("devtools")
devtools::install_github("TomBearpark/useful")
```

## Example

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

```{r example}

library(useful)
library(fixest)

df <- cars

df$dist1 <- df$dist
df$dist2 <- df$dist^2

m  <- fixest::feols(speed ~ dist1 + dist2, data = df)
rf <- useful::predict_poly(m, "dist", min = 2, max = 100, ref = 50, 
                           xvar_name = "dist")
useful::plot_rf_poly(rf, xvar = "dist")
```
