structenforcement

Tools for ensuring that data is correctly typed.

Without moving over to a strict type system such at that offered by the typed package or enforcing classes everywhere, this offers a straightforward approach to getting lists (and especially dataframes) into the correct types, where R’s extreme dynamism might infer something incorrectly when it comes to input data.

It is naturally best used in conjunction with other means of ensuring that structures keep the correct types once they’ve been cast. As of the initial implementation, this mostly cares about primitive types. The only class that is handled neatly is POSIXct.

Installation

You can install the development version of structenforcement like so:

remotes::install_gitlab("S_S_/structenforcement")

Example

library(structenforcement)

template_struct <- data.frame(
    "Sepal.Length"  = integer(0),
    "Sepal.Width"   = numeric(0),
    "Petal.Length"  = numeric(0),
    "Petal.Width"   = numeric(0)
)
type_checked_iris <- type_check(
    template_struct,
    iris,
    TRUE,
    c("casts", "missing", "excess")
)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
