rah_anchors(target, token = Sys.getenv("AHREFS_AUTH_TOKEN"),
  mode = "domain", metrics = NULL, limit = 1000, order_by = NULL,
  where = NULL, having = NULL)

`target`	character string. Aim of a request: a domain, a directory or a URL
`token`	character string. Authentication token. Should be available through enviromental variables after authentication with function `rah_auth()`
`mode`	character string. Mode of operation: exact, domain, subdomains or prefix. See more in Details section
`metrics`	character vector of columns to select. See more in Details section
`limit`	integer. Number of results to return
`order_by`	character vector of columns to sort on. See more in Details section
`where`	character string - a condition created by `rah_condition_set()` function that generates proper `"where"` condition to satisfy. See more in Details section
`having`	character string - a condition created by `rah_condition_set()` function that generates proper `"having"` condition to satisfy. See more in Details section

1. available metrics - you can select which columns (metrics) you want to download and which one would be useful in filtering, BUT not all of them can always be used in "where" & "having" conditions:

Column	Type	Where	Having	Description
anchor	string	+	+	Anchor text used in at least one backlink from the referring domain.
backlinks	int	+	+	Number of external backlinks found that are using the anchor text.
refpages	int	+	+	Number of pages found containing backlinks that are using the anchor text.
refdomain	string	+	-	Referring domain that contains at least one backlink using the anchor text.
refdomains	int	-	+	Number of referring domains that are using the anchor text when linking to the target.
first_seen	date	+	+	Least recent date when the Ahrefs crawler was able to visit the backlink that is using the anchor text.
last_visited	date	+	+	Most recent date when the Ahrefs crawler was able to visit the backlink that is using the anchor text.

2. "mode" parameter can take 4 different values that will affect how the results will be grouped.

Example of URL directory with folder:

Example URL: ahrefs.com/api/
exact: ahrefs.com/api/
domain: ahrefs.com/*
subdomains: *ahrefs.com/*
prefix: ahrefs.com/api/*

Example of URL directory with subdomain:

Example URL: apiv2.ahrefs.com
exact: apiv2.ahrefs.com/
domain: apiv2.ahrefs.com/*
subdomains: *apiv2.ahrefs.com/*
prefix: apiv2.ahrefs.com/*

3. "order_by" parameter is a character string that forces sorting of the results. Structure:

Structure: "column_name:asc|desc"
Single column example: "first_seen:asc" ~ this sorts results by first_seen column in ascending order
Multi column example: "last_seen:desc,first_seen:asc" ~ this sorts results by 1) last_seen column in descending order, and next by 2) first_seen column in ascending order

4. "where" & "having" are EXPERIMENTAL parameters of condition sets (character strings) that control filtering the results. To create arguments:

use rah_condition() function to create a single condition, for example: cond_1 <- rah_condition(column_name = "links", operator = "GREATER_THAN", value = "10")
use rah_condition_set() function to group single conditions into final condition string, for example: fin_cond <- rah_condition_set(cond_1, cond_2)
provide final condition to proper report function as a parameter, for example: RAhrefs::rah_anchors(target = "ahrefs.com", token = "0123456789", mode = "domain", metrics = NULL, limit = 1000, where = fin_cond, order_by = "first_seen:asc")
