Problem with `mutate()` input `data`.

[Ren]

I'm getting an error and I'm not sure what is wrong with my data. When looking over the raw file, I can't tell what needs to be fixed. Help?

Error: Problem with mutate() input data.
x missing value where TRUE/FALSE needed
Input data is map(.data$data, .f, ...).

Can you provide a reproducible example? It will help if you show us some code and an example of your data. FAQ: How to do a minimal reproducible example ( reprex ) for beginners

library(rstatix)

these data are titled spleen

#statistical test run

stat.test <- spleen %>% group_by(group,detail)%>%

• wilcox_test(value ~ sex, paired = FALSE)
  

#error

Please provide your data in code rather than as a screenshot. We can test it if it is in code (see the article).

Can you post the output of dput(spleen) or dput(head(spleen)) if there is a lot of data?

In the example, the grouping variable seems to be numeric. It is strange that you can't do it with a factor variable.

Perhaps raise an issue:

The wilcox.test function has this form when used with a formula

wilcox.test(formula, data, subset, na.action, ...)

You cannot use the %>% operator to pass in the data set because data is the second argument of wilcox.test, not the first. Also, I doubt wilcos.test knows how to handle the result of group_by(). You should use the subset argument.

[williaml]

It is a different wilcox_test() from the package rstatix.
