【问题描述】：

我有两个数字列表，我想以闪亮的文本输出，但我很难输出多行。假设这两个列表是：

violations1 <- c(1,2,3,5)
violations2 <- c(66,354,78)

对于输出，我希望看到：

Violations of Type 1: 1, 2, 3, 4, 5
Violations of Type 2: 66, 354, 78

但是当我使用

paste("Violations of Type 1:", violations1, "Violations of Type 2:", violations2)

我明白了

[1] "Violations of Type 1: 1 Violations of Type 2: 66" 
[2] "Violations of Type 1: 2 Violations of Type 2: 354"
[3] "Violations of Type 1: 3 Violations of Type 2: 78" 
[4] "Violations of Type 1: 5 Violations of Type 2: 66"

【解决方案1】：

使用paste 的collapse 选项：

#data
violations1 <- c(1,2,3,5)
violations2 <- c(66,354,78)

#result
paste("Violations of Type 1:",paste(violations1,collapse = ","))
#[1] "Violations of Type 1: 1,2,3,5"
paste("Violations of Type 2:",paste(violations2,collapse = ","))
#[1] "Violations of Type 2: 66,354,78"
