You didn't get an error. You got a warning. Did you read what it said? It seems pretty self-explanatory, and also gives you other things you can read for further information.

In addition, you can just copy and paste the output and then highlight and click the button that says 'CODE' to make it more legible.

Thanks a lot for your comment. I've read what it siad but I don't know how to deal with it... Need I change my Rcpp version back to version 1.0.7? I've just run 'library (xcms)' sucessfully, yet got this warnning message:

Warning message:

  mzR has been built against a different Rcpp version (1.0.7)
than is installed on your system (1.0.8). This might lead to errors

Also, I've search this question in our forum. Some said that Rcpp has got enhancement and the warnning message could just be ignored. Is that OK? I'm just start learning R. Still preparing for the long haul. Are there any fundamental learning materials that you recomment? I would be appreciated to see your comments.

Have you gone to https://github.com/sneumann/mzR/wiki/mzR-Rcpp-compiler-linker-issue and read what they say you can do?
