范围 - 嵌套函数

Question

我在下面有一些代码。现在我有一种方法可以在GETAPI调用之后将函数lOriginal <- GETAPI放在代码的最后？

据我了解，如果在GETAPI()调用之前尚未评估GETAPI函数，则R不会在文档中搜索它。但为什么不呢？

如果我将GETAPI函数放在代码的最后，我会得到错误：

  

无法找到GETAPI功能

代码

library(ggplot2)
library(digest)
library(stringi)
library(jsonlite)
library(plyr)

#'@export
#'

query  <- function(area = "stockholm", type="lägenhet", sincesold = "",  FUN  = "", limit = 500, offset = 0) {

  GETAPI  <- function(area = "stockholm", type="lägenhet", sincesold = "",  FUN  = "", limit = 500, offset = 0) {... }

  #raw data fetch + add new columns
  lOriginal  <- GETAPI(area, type, sincesold, FUN, limit, offset)
  lOriginal  <- lOriginal[order(lOriginal$publish, decreasing = TRUE, na.last = TRUE), ]
  row.names(lOriginal)  <- NULL
  lOriginal$AreaSize <- round_any(lOriginal$livingArea, 10, floor)
  lOriginal$PriceDiff  <- lOriginal$soldPrice - lOriginal$listPrice

  #Reclass
  lOriginal$AreaSize  <- as.factor(lOriginal$AreaSize)
  lOriginal$published  <- as.Date(lOriginal$published)
  lOriginal$soldDate  <- as.Date(lOriginal$soldDate)

  return (lOriginal)
}
