如何使用fb_insights功能，使用R

Question

我试图用fbRads库使用R.

https://cran.r-project.org/web/packages/fbRads/fbRads.pdf

我有一个有效的fbaccount对象由fb_init函数返回从Facebook导入数据导入从Facebook的数据和然后我试图使用完全相同的文档这里所说的同一个例子：

l <- fb_insights(fbacc, date_preset = 'today', level = 'ad') 
library(rlist) 
list.stack(list.select(l, date_start, date_stop, ad_id, total_actions, 
total_unique_actions, total_action_value, impressions, unique_impressions, 
social_impressions, unique_social_impressions, clicks, unique_clicks, 
social_clicks, unique_social_clicks, spend, frequency, deeplink_clicks, 
app_store_clicks, website_clicks, reach, social_reach, ctr, unique_ctr, 
cpc, cpm, cpp, cost_per_total_action, cost_per_unique_click, 
relevance_score = relevance_score$score)) 

在可变l，我得到：

>print(l) 
[[1]] 
list() 

然后

>list.stack(list.select(l, date_start, date_stop, ad_id, total_actions, 
+      total_unique_actions, total_action_value, impression .... [TRUNCATED] 
Error in eval(expr, envir, enclos) : object 'date_start' not found 

什么似乎不是在这里工作？我该如何解决？

我设法使用以下命令fb_insights(fbacc, level='ad', time_range = '{"since":"2015-08-01","until":"2016-06-31"}')获得Fb广告数据，当时间间隔未由time_range定义时，我无法获取数据。
