as.which: Coercion to (positive) integer positions
In OHDSI/bit: A Class for Vectors of 1-Bit Booleans

Description Usage Arguments Details Value Author(s) See Also Examples

Coercing to something like the result of which which

as.which(x, ...)
## Default S3 method:
as.which(x, ...)
## S3 method for class 'ri'
as.which(x, ...)
## S3 method for class 'bit'
as.which(x, range = NULL, ...)
## S3 method for class 'bitwhich'
as.which(x, ...)

`x`	an object of classes `bit`, `bitwhich`, `ri` or something on which `which` works
`range`	a `ri` or an integer vector of length==2 giving a range restriction for chunked processing
`...`	further arguments (passed to `which` for the default method, ignored otherwise)

as.which.bit returns a vector of subscripts with class 'which'

a vector of class 'logical' or 'integer'
