R 中的代码块给出“意外符号”错误

Question

For some reason, R markdown literally won't do anything without some vague error. I'm trying to run the simplest code chunk, but I get an error. I've tried both manually typing the chunk, and inserting it from R's selection

Answer 1

1.s is not a valid symbol in R ,

(1) if you are trying to name a variable, it cannot start with a number

(2) name like s.1 is valid, but you have to make it an object, ie either assign a value or a function etc. s.1=1 will work in the Rmarkdown

(3) if you just want to put some text here, you need to comment them by putting # before it, ie #1.s
