lapply(thing, function(x) x[['p.value']]) --works very well, thank you. Not to be a chore, but I'm interested in comparing the results of wilcox.test--and the methodology we've employed so far--with the results and methodology of wilcox_test (library("coin")). So, I'd like to compare groups 5 and 6 across A through H using wilcox_test, and then I'd like to extract the p-values. Going through the same methodology as above, but replacing wilcox.test with wilcox_test has failed, and so has the p.value extraction method: lapply(thing, function(x) x[['p.value']]) .
I believe the latter failure has to do with the fact that the coin package has a built-in class and built-in extraction method (pvalue() to extract and class "IndependenceTest"), but I don't know how to work around it. For example, for a single comparison: wilcox_test(A~Group, Dtb) works fine, and pvalue(wilcox.test(A~Group, Dtb)) extracts the p-value. So, any ideas about how to compare groups 5 and 6 across A through H using wilcox_test?
