df1 <- data.frame(name = c("A","B","C"), f1 = c(1,2,3), f2 = c("zz","mo","do"))
df2 <- data.frame(name = c("D","B","C"), f1 = c(1,4,6), f2 = c("ok","no","do"))
df3 <- data.frame(name = c("D","E","C"), f1 = c(1,2,3), f2 = c("so","yo","kl"))
我想将它们合并到一个数据框中,使其看起来像
name df.1f1 df1.f2 df2.f1 df2.f2 df3.f1 df3.f2
A 1 zz na na na na
B 2 mo 4 no na na
C 3 do 6 do 3 kl
D na na 1 ok 1 so
E na na na na 2 yo
虽然我可以使用重复的dplyr :: full_join来做到这一点,但它太繁琐了。任何人都有更好的方法来做到这一点?

如果您有多个数据框,可以列出它们。 灵感来自vaettchen
Reduce(function(x,y) merge(x,y,by="name",all=TRUE) ,list(df1,df2,df3))

与within
一样,有很多方法。对我来说,嵌套合并可以很好地完成这项工作:
