Use this function to generate simple code asserstions about a
`data.frame`

.

1 | ```
generate.assertions(dat, max.level.show = 12, digits.compare = 6)
``` |

`dat` |
A |

`max.level.show` |
Maximum number of factor levels for which to generate an assertion. |

`digits.compare` |
How many decimal digits to include in comparisons of numeric data? |

Assertions are generated about the number of rows and columns in the
`data.frame`

, and about each column it contains.
An assertion is generated about the class of the column, and the number
of missing values (`NA`

). If the column has a `label`

attribute, then as assertion is generated for that as well.
Further assertions depend on the `class`

of the column.
For `factor`

s, the number of levels is asserted. If this does
not exceed `max.level.show`

then the `levels`

are
asserted as well. For numeric data, the range (rounded to
`digits.compare`

is asserted.

None (`invisible`

'`NULL`

').
