如何在 paste() 语句中包含具有多个元素的向量？

Question

有一个名为 error.list 的字符向量，其中包含多个元素。我试图在我的粘贴语句中包含完整的矢量，如下所示：

paste("Hi, Your data has the following errors:", error.list," Regards, XYZ", 
sep='').

但是我遇到了一个错误。控制台说它不能在单个粘贴语句中添加所有元素。可以帮我解决这个问题吗？还有其他方法吗？

Concatenate Strings

您的方法可行 For inputs of length 1 但您有一个向量。

Because error.list is a vector, use one of the following methods:

error.list <- c("a", "b", "c")

paste(c("Hi, Your data has the following errors:", error.list, " Regards, XYZ"), sep = " ")

Provide the output:

[1] "Hi, Your data has the following errors:" "a"                                      
[3] "b"                                       "c"                                      
[5] " Regards, XYZ"

一行使用参数collapse = :

paste(c("Hi, Your data has the following errors:", error.list, " Regards, XYZ"), sep = "  ", collapse = " ")

Provide the output:

"Hi, Your data has the following errors: a b c  Regards, XYZ"

or you can use paste0() with parameter collapse = to get one line output, for also using the error.list as vector:

paste0(c("Hi, Your data has the following errors:", error.list, " Regards, XYZ"), collapse = " ")

Provide the output:

[1] "Hi, Your data has the following errors: a b c Regards, XYZ"
