- Keywords
- datasets

##### Usage

`data(hoef)`

Treatment 4: \(\tau_4 = 6\)

Treatment 5: \(\tau_5 = 6\)

##### Format

This data frame contains the following columns:

- x1
x-coordinate of the plot.

- x2
y-coordinate of the plot.

- dat
the

*artificial*data.- trat
the treatment number.

- ut
the data from the uniformity trial, without the treatment effect.

##### Examples

```
# NOT RUN {
hoef.geo <- as.geodata(hoef, covar.col=4)
summary(hoef)
summary(hoef.geo)
points(hoef.geo, cex.min=2, cex.max=2, pt.div="quintiles")
# }
```
