Use purrr() to rather than lapply for arbitrary city/county pairs in tidycensus?
问题 I've got a giant lapply running to download a file of data. But it seems clumsy. But mapply does not seem right, as I don't want all state/county combinations. I hear good things about map(). Can anyone furnish an example of how I might use purrr() command 'map' for the following code? library(tidycensus) library(sf) mykey<-"youhavetogetyourownimafraid" #variables to test out the function############# x<-"06" y<-"073" z<-"2000" setwd("N:/Dropbox/_BonesFirst/149_Transit_Metros_BG_StateSplit_by
