用R语言处理二个表格数据
data1<-data.frame(name=c("TOM","Jack","MAx","JIM"),sex=c("M","M","NA","F"),age=c("12","12","14","15"))

data2<-data.frame(name=c("TOM","Jack","MAx","JIM"),sex=c("M","M","F","F"),age=c("12","12","NA","15"))
然后将二个数据集合并，第一个数据集和第二个数据集里面都有一个空的数据，但是对应的数据集不为空，想将这两个表格合并，空元素由其他数据集对应的元素补充
效果就是
data3<-data.frame(name=c("TOM","Jack","MAx","JIM"),sex=c("M","M","","F"),age=c("12","12","14","15"))

求解，找了很多向相关知识，无法解决
