rbind 多个数据集 [英] rbind multiple data sets

问题描述

我有 3 个数据集要绑定在一起.我已将我的列重命名为相同的:

names(DF1) <- c("A", "B", "C")名称(DF2)<- c(A"，B"，C")名称(DF3)<- c(A"，B"，C")

他们每个人都有不同数量的观察(分别为 34、54、23)

但是，当我尝试使用 rbind 函数时，它返回错误:

total <- rbind(DF1, DF2, DF3)

<块引用>

match.names(clas, names(xi)) 中的错误:名称与以前的名称不匹配

从其他已回答的问题来看，错误应该是由于不同命名的列而出现的，但我已经检查并重新检查它们的重命名是否相同.

我想最终得到一个总数据集，其中包含 111 个带有列标题的观察值.我是 R 的初学者，其他问题的许多答案都让我望而却步.有没有人能够用外行的话来回答这个问题?

解决方案

你可以使用 do.call，像这样:

do.call("rbind", list(DF1, DF2, DF3))

注意 do.call 的第二个参数是一个列表.

I have 3 data sets that I want to rbind together. I have renamed my columns to be the same:

names(DF1) <- c("A", "B", "C")
names(DF2) <- c("A", "B", "C")
names(DF3) <- c("A", "B", "C")

They have each got different numbers of observations (34, 54, 23, respectively)

However, when I try with an rbind function, it returns the error:

total <- rbind(DF1, DF2, DF3)

Error in match.names(clabs, names(xi)) : names do not match previous names

From other answered questions the error should arise because of differently named columns, but I have checked and rechecked that they have been renamed the same.

I would like to end up with a total dataset with a total of 111 observations with column titles. I am a beginner to R, so many of the answers from other questions elude me. Would anyone be able to answer this in layman terms?

解决方案

You can use do.call, like so:

do.call("rbind", list(DF1, DF2, DF3))

Note that second argument of do.call is a list.
