Hello,

I am trying to using amp_heatmap function to draw heatmap for 16S data. But the facet_by parameter gave the following error. I have searched google and tried, but have not fixed this issue yet.

amp_heatmap(d,group_by = "Time_point",

• facet_by = "Group",
• tax_aggregate = "Genus",
• tax_show = 25) Error in fix.by(by.y, y) : 'by' must specify a uniquely valid column

Any help or suggestion will be appreciated. Thanks in advance!

Best regards, Jessie

Hi there!

I have find the solution to this error. That is, I changed the column name "Group" to "Subject_type". It does works! It seems that "Group" cannot be used as column names (Is it the 'key words' of this ampvis2 package?) when calling the amp_heatmap function. I am not sure about this currently, though.

Best regards, Jessie

Hi Jessie.

Yes it could be that the variable name Group can cause some trouble. But simply rename it and it should work fine.

I see. Thank you for your information!

Best regards, Jessie
