This is the learning set of the toy data, i.e. 1000 rows of the whole 1500 row dataset.

Columns `"X1"`

, `"X2"`

, ..., `"X10"`

were generated
with `rnorm`

to follow a standard normal distribution.

Column `"y"`

is a linear combination of `"X1"`

, `"X2"`

,
`"X3"`

, coefficients `(1:3)/sqrt(sum((1:3)^2))`

, yielding a
theoretical standard normal distribution.

Column `"noise"`

was also generated from the standard normal
distribution.

Use ```
file.show(system.file("toyDataSrc", "sisalToy.R",
package="sisal"))
```

to view the script that generated the data.
