Hello All,
Thanks a lot for the helpful suggestions. I wonder how ties are handled
for the rank sum test by wilcox_test and wilcox.exact? For instance,
Ties handling was mainly a problem back in the day when recursion
formulas were used for the

Hello peter,
Thanks for the comment. wilcox.exact is simpler as you pointed out but the
fact that it is no longer being developed is somewhat concerning.

Admittedly, 'coin' is being actively developed and has a lot more bells

Hello All,
Thanks a lot for the helpful suggestions. I wonder how ties are handled

software such as Minitab correct for ties by adjusting the variance of the
test statistic, and actually provide the p values before and

Hello Greg,
Thank you so much for your kind assistance. It looks like there's no way
around using the formula format. I longed in vain for a simpler script
more like the wilcox.test format. Thanks again.

Dear All,
I have two simple data samples (no groups or factors, etc.) and would just
like to compute the two-sample Wilcoxon Rank Sum test using the wilcox_test
function contained in the coin package, which is reportedly better than the
regular wilcox.test function because it performs some
What have you tried so far? Have you read the help page? have you run the
examples on that page?
I would expect that it is something as simple as
library(coin)
wilcox_test(x,y)
or
wilcox_test( y ~ group )
But you should trust the help page more than the expectations of someone
who has not
I thought (hoped) wilcox_test(x,y) would do it but it doesn't and the
package maintainer says the data have to be rearranged but does not specify
how. Thanks

Ok, it looks like the function mainly works through the formula syntax. It
still would have been nice to have a reproducible example of what your data
may look like, but I can show an example with simulated x and y:
x - rpois(10, 3)
y - rpois(11, 3.1)
mydf - data.frame( vals = c(x,y),
