Hi I receive a very strange error message after trying to do t-test. When I write the code t.test(x) I get an error message: error in t.test(x) : function "sqr" not found
I don't understand this problem. Can someone help me how to do it right? Thanks a lot :) ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
