## Individual States

# results: asis #output raw md content 

STATE_vec <- c("AL", "AK", "AZ", ...)

#create empty list 
res <- vector("list", length = 3L)

#run loop 
for (i in 1:length(STATE_vec)) { 
  
  #run sub w/ state, save in list
  res[[i]] <- knitr::knit_child(
      "stateplot.qmd"      
    , quiet = TRUE
    , envir = environment()
    )
}

#unlist and paste together w/ a break 
cat(unlist(res), sep = '\n')

#specify which state should be used
this_STATE <- STATE_vec[i]  

### `r this_STATE`
