I have a data set as below "temperature" "gender" "hr" 96.3 1 70 96.7 1 71 96.9 1 74 96.4 2 69 96.7 2 62 96.8 2 75
Gender code (1) means males and Gender code (2) means females. I have to split the data by gender and then perform a* two-sample tes*t to see whether the population means are equivalent. When using a function to solve this I should use the *notation for stacked data*. I *cannot assume equal variances* How can I code them? I am just a beginner for R programming Thanks -- Joanna Thuc Quyen Nguyen [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
