如何在R中使用字符串打印数值

Question

我有一个已分配给变量的整数，我想将它打印到控制台但我收到错误。下面的代码和示例

number <- 64
print("I want to print this number: " + number)

但我收到消息：“错误：二元运算符的非数字参数” 我希望看到像

这样的东西

[1] "I want to print this number: 64"

Answer 1

使用sprintf

sprintf("I want to print this number: %i", number)
#[1] "I want to print this number: 64"

或paste0

paste0("I want to print this number: ", number)
#[1] "I want to print this number: 64"
