r - 在 R 中矢量化 API 数据请求

Question

有没有办法通过创建一个函数并迭代一系列年份来矢量化这些数据请求？我知道如何使用循环来做到这一点，但我想知道我是否可以利用矢量化的好处。

y_2015_2011 <- ct_search(reporters = "Canada", partners = "All", trade_direction = "all",
                     start_date = 2011,end_date = 2015,commod_codes = 030613)

y_2005_2009 <- ct_search(reporters = "Canada", partners = "All", trade_direction = "all",
                      start_date = 2005,end_date = 2009,commod_codes = 030613)

y_2010_2014 <- ct_search(reporters = "Canada", partners = "All", trade_direction = "all",
                      start_date = 2010,end_date = 2014,commod_codes = 030613)
