extracting p-values in scientific notation
is(x)
[1] "htest"
# take a look at stats:::print.htest format.pval(x$p.value)
[1] "< 2.22e-16" Does that answer your question? KK

Dear all How does print.htest display the p-value in scientific notation?
(x <- cor.test(iris[[1]], iris[[3]]))
? ? ? ?Pearson's product-moment correlation data: ?iris[[1]] and iris[[3]] t = 21.65, df = 148, p-value < 2.2e-16 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: ?0.8270 0.9055 sample estimates: ? cor 0.8718 Above the p-value comes as '< 2.2e-16', while inspecting the object I get a good old '0'.
x$p.value
[1] 0 I tried to inspect print.htest but couldn't find it. I also played with format, round and the like to no avail. Any pointers?
