Create NCI GDC filters for limiting GDC query results

Source: R/filters.R
make_filter.Rd

Searching the NCI GDC allows for complex filtering based on logical operations and simple comparisons. This function facilitates writing such filter expressions in R-like syntax with R code evaluation.

Usage

make_filter(expr, available_fields)

Arguments

expr

a lazy-wrapped expression or a formula RHS equivalent

available_fields

a character vector of the additional names that will be injected into the filter evaluation environment

Value

a list that represents an R version of the JSON that will ultimately be used in an NCI GDC search or other query.

Details

If used with available_fields, "bare" fields that are named in the available_fields character vector can be used in the filter expression without quotes.
