When I do t.test on two distributions (see example below), it outputs numerous data about the t.test. What I'd like to do is individually capture some of this data and assign it to other variables. However, I am unable to find anything in the help section. In the example below, the t value is -4.0441 and the p-value is 0.006771 How can I assign these values to two variables, let's say tVal and pVal?
tt <- t.test(d[1], d[2], var.equal=TRUE) tt$statistic tt$p.value unclass(tt) names(tt)
