'reverse_base' variable not found

First of all this is a great alternative to Google revgeocode so thank you for working on this. Just have a few minor issues. See below: I would appreciate you guys helping me on this.
I've encountered this issue when I ran the reverse_geocode function:
reverse_geocode <- function(params) {
tryCatch({
res <- GET(reverse_base, query=params, timeout(getOption("NOMINATIM.TIMEOUT")))
stop_for_status(res)
ret <- content(res)
if (length(ret) == 0) return(NULL)
ret_names <- intersect(names(ret),
c("place_id", "licence", "osm_type", "osm_id",
"lat", "lon", "display_name", "class", "type", "importance"))
tmp_df <- data.frame(t(sapply(ret_names, function(x) { ret[[x]] })), stringsAsFactors=FALSE)
if ("address" %in% names(ret)) {
tmp_df <- cbind.data.frame(tmp_df,
data.frame(t(sapply(names(ret[["address"]]),
function(x) { ret[["address"]][[x]]} )),
stringsAsFactors=FALSE),
stringsAsFactors=FALSE)
}
tmp_df$lat <- as.numeric(tmp_df$lat)
tmp_df$lon <- as.numeric(tmp_df$lon)
return(tmp_df)
}, error=function(e) { message("Error connecting to geocode service", e)})
return(NULL)
}

It's looking for the reverse_base variable definition in the GET statement and I can't seem to find it. Please assist. Thanks.
Have you tried the revgeo package? I can recommend it. Demo of it in action (we recently switched to it): http://geocompr.robinlovelace.net/location.html#define-metropolitan-areas
This is excellent!!! Just ran the revgeo package using the embassies coordinates, it works excellent and I used photon as the provider and I like the output = "frame" because it separates each element (house num, street, city, etc) into columns. By the way, is there a limit on query using photon? I've acquired a MapQuest API, and correct me if I'm wrong but it shows 15K/month limit?Is the API applicable here when using photon provider? Again, thanks much. Appreciate the recommendation. Also I like the paper posted on the link about Geomarketing!
addresses <- revgeo(longitude = embassies$lon, latitude = embassies$lat, provider = "photon",+ API = NULL, output = "frame")[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=69.1835&lat=34.53311"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=19.818698&lat=41.327546"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=12.50891&lat=41.91534"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=3.0166&lat=36.76148"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=-171.76462&lat=-13.83282"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=-3.686115&lat=40.479094"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=31.043559&lat=-17.820705"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=-59.59998&lat=13.09511"[1] "Getting geocode data from Photon: http://photon.komoot.de/reverse?lon=-59.59998&lat=13.09511"> head(addresses) housenumber street city state zip country1 House Number Not Found Torabaz Khan Kabul Kabul 0093 Afghanistan2 House Number Not Found Rruga Tafaj Tiranë Central Albania 1000 Albania3 House Number Not Found Street Not Found Rome Lazio 00157 Italy4 House Number Not Found Street Not Found Ben Aknoun Algiers 16000 Algeria5 House Number Not Found Mulinu'u Road Apia State Not Found Postcode Not Found Samoa6 House Number Not Found Street Not Found Madrid Community of Madrid 28001 Spain

Great. Not sure about API limits with Photon. Glad the chapter was of use. Any comments/suggestions on that welcome!
late on this but I just re-connected my mapquest account and tried this and it worked.
however, i moved the internal globals to a new aaa.R (which shouldn't have been an issue but ¯_(ツ)_/¯)
