Hello! Thank you for your amazing work developing the MaAsLin tool. I have successfully been able to upload my data into the R environment and run the tool. However, the tool appears to be trying to create boxplots for the continuous variables and it ends up printing out a series of empty graphs (just axes; no data). If I check the structure of the variables in the data frame they are listed as numeric. Is there something else I can do to signal that I am using continuous variables (a set of 4 continuous variables in this specific case) as fixed effects in the model?
Thank you for your assistance,
