GMPR transformation function is missing

[thecorz]

Describe the Bug
When I try to normalise the data using the GMPR method, I get an error that says that GMPR function is missing

Reproducible Example
Sorry, to reproduce the data is too complicated. But given that MicrobiomeData is a MicrobiomeStat object...

MicrobiomeData.gmpr <- mStat_normalize_data(MicrobiomeData, "GMPR")

Expected Behavior
Outputs transformed values

Actual Behavior
Outputs and error:

Error in GMPR(otu_tab) : could not find function "GMPR"

Screenshots
N/A

Environment Information:

• Operating System: Windows 11
• R Version: 4.3.2
• Package Version: 1.13

Additional Context

Dear @thecorz,

Thank you for reaching out and describing the issue you're facing with our package. From the error message you've provided, it seems like the GMPR function is not being recognized in your current R session. This typically occurs when the required package for the GMPR function is not loaded.

To resolve this issue, you should load the GUniFrac package before attempting to normalize your data with the GMPR method. You can do this by using the library() function in R. Please insert the following line of code at the beginning of your script or before you call the mStat_normalize_data() function:

library(GUniFrac)

This will load all the necessary functions from the GUniFrac package, including the GMPR function, into your R session. After executing this line, you should be able to normalize your MicrobiomeData using the GMPR method without encountering the error.

Please let me know if this solution works for you or if you encounter any further issues.

Best regards,

Chen YANG
