Placing to-be-imported operators inside double vs. single quote? #52

Closed chunyunma closed 3 years ago

chunyunma commented 3 years ago

I really like the philosophy behind import and introduced it to students in my class. Recently, a couple of students mentioned to me that when they tried to import the pipe operator %>% from magrittr package, placing the pipe operator inside a pair of single vs. double quotation marks made a difference. Only import::from(magrittr, "%>%") worked for them, whereas import::from(magrittr, '%>%') did not.

I could not replicate this problem myself either on a Mac or on a Windows. Both single and double quotes worked properly for me. I even tried a pair of backticks ` `, which also worked. For the record, both students who had trouble with single quotes were on Windows.

I am aware of the single vs. double quotes subtleties and that double quotes are the preferred method. However, I still want to know whether anyone is aware of such differences for import method and if so, why.

Thank you very much!

Thanks for the support of the package.

I cannot replicate the issue, and don't know how that would happen:

> identical(quote("hello"), quote('hello'))
[1] TRUE

If you get more information to share, or a stack trace, that would maybe shed some light...

Thank you very much for the suggestion! The student and I tried on their machine again, but the error seems unable to reproduce. I have asked the students to keep an eye out and save the stack trace if it happens again.

I will close the issue for now and re-open it if I have more information to share. Thanks again!
