Error on R shiny app metaOmics; object %AND% not found

I'm trying to get a shiny app on R to work, i follow the steps (libraries needed to install on R from the tool tutorial), but the new shiny window that appears shows the message error: object '%AND%' not found. (the app is available on docker and when I pull it through docker it works but I need to work on R on my comp.) Does anyone have any advice what could be missing/ done to address that error? the tool is metaOmics https://github.com/metaOmics/metaOmics in case someone has experienced it in specific Thank you,

shiny r metaomics

Compare R versions maybe? First step would be to find which package exports the %AND% operator.

There is a git issue open about this message. If you look at the code, the only reference to %AND% is inside directoryInput.R:

shiny:::`%AND%`(label, tags$label(label))

The shiny code doesn't seems to contain any %AND%.

Good catch on the usage! OP should add their experience on that git issue - that issue looks woefully under-detailed.

I found this message on the issue section of another app (statOmics):

Apparently the shiny:::%AND% function was removed from the shiny package while MSqRob was depending on it.
I have re-introduced this function, everything should now work again.
Please try reinstalling MSqRob via
devtools::install_github("statOmics/MSqRob@MSqRob0.7.7")

I am not sure what is the relationship between statOmics and metaOmics, but you can try to re-define %AND% yourself.

# deprecated definition
`%AND%` <- function(x, y) {
    if (!is.null(x) && !isTRUE(is.na(x)))
       if (!is.null(y) && !isTRUE(is.na(y)))
          return(y)
    return(NULL)
}
