Im trying to do a t test between two means of a test of two groups but I have been unable to get a result. Im receieving this error

Warning in is.na(y) : is.na() applied to non-(list or vector) of type 'language' Error: ! Can't combine SpeakGroup<character> andGmeanResponse` . Backtrace:

  1. deledata %>% ...
  2. stats:::t.test.default(...)
  3. tibble:::[.tbl_df(x, xok)
  4. tibble:::tbl_subset_matrix(x, j, j_arg)
  5. vctrs::vec_c(!!!values, .name_spec = ~.x)
  6. vctrs (local) <fn>()
  7. vctrs::vec_default_ptype2(...)
  8. vctrs::stop_incompatible_type(...)
  9. vctrs:::stop_incompatible(...)
  10. vctrs:::stop_vctrs(...)`

This is the code im using:

deledata <- groupwithmean %>%
  filter(Test == "ESP")
deledata

The output

enter image description here

and the code for the t test

ttestDELE <- deledata %>%
  t.test(GmeanResponse ~ SpeakGroup, mu=0, alt="two.sided", conf=0.95, var.eq=F, paired=F)

ttestDELE

Thanks in advance

  • The only thing we need to help you is the data. So in your console paste `dput(deledata)`. Copy the output and paste it to your question via the Edit button below the question. Then tell us which one is the value and which one is the group to test. – TarJae Jul 23 '22 at 16:33
  • You are missing the data argument, try `deledata %>% t.test(GmeanResponse ~ SpeakGroup, data = ., etc)`. – Rui Barradas Jul 23 '22 at 17:01
