If I directly copy the R statement from the Internet and paste it into my R editor window, quotation marks may create errors. This is the error I got.
Error: unexpected input in "setwd(“"
Notice it involves “ and ”. They look aesthetically pleasing as the first one clearly indicate the beginning quote and the second one the quotation end. R and other software programs do not understand them. I have to replace them with " for both.
I installed it and activated it, so if you copy the following, it should run on R on your machine without a problem.
Note: I am not exactly sure if it is working right now. I activated it, but I don't see any way to specify options. Maybe just activating it works, but still when I pasted this here:
It still looks like it is using the old quotation marks.
I used to use this long time ago and it used to work well.
