如何用 R 中的字符串打印数值

Question

我有一个已分配给变量的整数，我想将其打印到控制台，但出现错误。下面的代码和示例

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

但是我收到消息：“错误：二元运算符的非数字参数”我想看到类似的东西

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

Answer 1

用 sprintf

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

或者 paste0

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