r - 计算区域经济增长序列，即。四个国家的增长系列放在一起

Question

我想在 R 中使用 10 年的实际 gdp 系列计算选定国家的区域增长率。请问我该如何解决这个问题？

country1<-c(7297.92,7606.31,7831.29,8288.33,8455.79,9312.52,9715.96,10273.14,10680.06,11250.53,11909.55,12544.70,13127.16)

country2<-c(6867.71,7490.89,7507.96,7768.33,7870.16,8320.16,9236.60,9820.07,10537.69,11195.42,11406.84,12161.22,12690.59)

country3<-c(36451.25,36471.89,36244.85,36100.36,36874.38,39475.09,42137.73,44531.85,46815.82,47725.57,46738.43,46795.16,46014.77)

country4<-c(36039.85,37943.41,39415.40,41327.04,42678.11,44395.22,46435.70,48385.18,50656.26,52899.57,55124.29,57626.41,60388.82)

我浏览了 REAT 包（https://cran.r-project.org/web/packages/REAT/REAT.pdf），但不知道如何完成它。
