Hello, I'm using R to do statistics on datasets, and now I need an f-test, which I can't find in R. Is there such a thing as an f-test. T-test seems to work fine, but ..

T-test seems to work fine, but ..It all depends on what you mean by an 'F test' since there are numerous tests for all sorts of things that share that name. The function var.test() compares variances as an F test. The aov() function also does an F test on the significance of individual variables in an analysis of variance model. See help(var.test) and help(aov) for more details.
