as.which.which {bit} | R Documentation |
Coercion to (positive) integer positions
Description
Coercing to something like the result of which which()
Usage
## S3 method for class 'which'
as.which(x, maxindex = NA_integer_, ...)
## S3 method for class ''NULL''
as.which(x, ...)
## S3 method for class 'numeric'
as.which(x, maxindex = NA_integer_, ...)
## S3 method for class 'integer'
as.which(x, maxindex = NA_integer_, is.unsorted = TRUE, has.dup = TRUE, ...)
## S3 method for class 'logical'
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, ...)
as.which(x, ...)
