Hello,

I've gone through the download process, and made sure that I have all the necessary packages installed. However, at the very first step, I am getting this error:

> qza\_table \<- read\_qza("~/Iceland-2014-data/Iceland-2014-table-data2.qza")  
> Error in read\_qza("~/Iceland-2014-data/Iceland-2014-table-data2.qza") :  
> could not find function "read\_qza"

... even though the install seemed to work fine, as seen here:

> devtools::install\_github("jbisanz/qiime2R")

I am also unable to get ?read\_qza to return anything, however, ??read\_qza does open the documentation in the help window.

Any suggestions would be appreciated. Thanks.

Hi @16sIceland!  
I don't have much mileage in R, but I suspect that you're unable to use the function because you haven't loaded the library yet. Can you double-check that you've loaded the library using the `library` command?

I think `?` only works if the library's been loaded, but `??` will bring up search results for any installed libraries regardless of loading.

Best,  
Chris 🐍

OK, I fixed it! I forgot to load the library with library(qiime2R).
