Description
Enable the Use of 'metacore' to Help Create and Check Dataset.
Description
Uses the metadata information stored in 'metacore' objects to check and build metadata associated columns.
README.md
metatools 
The goal of metatools is to enable the use of metacore objects. Metatools can be used to build datasets or enhance columns in existing datasets as well as checking datasets against the metadata in metacore.
Installation
You can install the latest released version of metatools from CRAN with:
install.packages("metatools")
And the current development version from GitHub with:
devtools::install_github("pharmaverse/metatools")
Example
Here is a basic example of some functions to build datasets and create new columns.
library(metatools)
library(metacore)
library(haven)
library(dplyr)
#>
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#>
#> filter, lag
#> The following objects are masked from 'package:base':
#>
#> intersect, setdiff, setequal, union
load(metacore_example("pilot_ADaM.rda"))
metacore <- metacore %>%
select_dataset("ADSL")
ds_list <- list(DM = read_xpt(metatools_example("dm.xpt")))
# Pull in columns from DM to be in ADSL
adsl <- build_from_derived(metacore, ds_list, predecessor_only = FALSE)

Metatools can also be used to run checks
data <- read_xpt(metatools_example("adsl.xpt"))
# Checks can be run on a single column
