qiime2R support requests


#1

Hi @jbisanz !

I installed tidyverse and qiime2R in my laptop (Windows10) which went through successfully. However, when I attempt to import the .qza files into R console I get the following error:

taxonomy<–read_qza(“taxonomy-blast.qza”)
Error in unzip(file, exdir = tmp) : ‘exdir’ does not exist

SVs<-read_qza(“table-no-eukaryote.qza”)
Error in unzip(file, exdir = tmp) : ‘exdir’ does not exist

Please help me out from this error. Thanks!

The function is trying to unzip the artifact to /tmp; however this may not be available on your windows system. You can specify a directory using the tmp="yourdirhere" argument. Something like this would work:

dir.create("scratch") #create a new folder in your working directory called scratch
tax<-read_qza("taxonomy-blast.qza", tmp="scratch")

This worked, but a new error pops up, here it is:

Any solution to this error? Thanks!

Ahh, the issue lies in the sep="; ". This code assumed that your taxonomy string would have a space following the semicolon. if you switch to sep=";" I think it should work.
