定義一個跨越多行的字符串

Question

當字符串文字跨越多行時，可以在python中使用三引號"""..."""。

>>> string = """\ 
... Usage: thingy [OPTIONS] 
...  -h      Display this usage message 
...  -H hostname    Hostname to connect to 
... """ 
>>> 

在R中是否有像這樣的可能方式？

Answer 1

[R串也支持這樣的行爲：

string <- " 
    ... Usage: thingy [OPTIONS] 
    ...  -h      Display this usage message 
    ...  -H hostname    Hostname to connect to 
    ... " 

print(string) 

輸出：

[1] "\n... Usage: thingy [OPTIONS]\n...  -h   
      Display this usage message\n...  -H hostname 
      Hostname to connect to\n... "
