tbl_merge add p value ? with gt summar package R

I am a beginner in r and trying to create some tables using this great gtsummary package. My question is that is it possible to add p value on this ?

merge <- tbl_merge(
    tbls = list(gene_colt, colt),
    tab_spanner = c("**gene COLT**", "**COLT**")
  )%>% add_p()

output

I would suggest you merge your data before creating two separate tables, and add a new variable, e.g. table_id, to distinguish COLT data from gene COLT data.

Then you can run the following:

library(tidyverse)
library(gtsummary)

merged_data <-   # this will depend on how your data were structured...
    bind_rows(
        data1 %>% mutate(table_id = "gene COLT"),
        data2 %>% mutate(table_id = "COLT")
    )

merged_data %>%
tbl_summary(
    data = .,
    by = table_id
    ) +
    add_p(test = "chisq.test")

Yes, it is. The package is well-documented and you can find more information under this link. I would recommend to define the statistical test in the function, e.g., %>% add_p(test = "chisq.test") for a Chi-squared test. For a reference of what else is possible I would refer you to the documentation once again for lack of information in your question, i.e., it is unclear which test you would like to apply.
