ExtractField: Extract a specific field from a brenda.entries object.
In brendaDb: The BRENDA Enzyme Database

Description Usage Arguments Value Examples

Retrieve one field from all the brenda.entry objects. A column of EC numbers will be added to distinguish different enzymes.

1	ExtractField(res, field, entries = NULL)

`res`	A brenda.entries object from `QueryBrenda()`.
`field`	A string indicating the field to extract. Nested fields should be separated by `$`, e.g. `parameters$ph.optimum`.
`entries`	A character vector with values of EC numbers. This should be a subset of `names(res)`.

A tibble with all columns from the tibble in the given field, and extra columns containing the EC numbers and organisms.

df <- ReadBrenda(system.file("extdata", "brenda_download_test.txt",
                          package = "brendaDb"))
res <- QueryBrenda(brenda = df, EC = c("1.1.1.1", "6.3.5.8"),
                   n.core = 2)
ExtractField(res, field = "molecular$stability$general.stability")
ExtractField(res, field = "structure$subunits")
