Hello @rahel_park ,
There is a way to move the ordination.qza output into R for biplot visualization. I would do this using the qiime2R tutorial provided by @jbisanz. Specifically the command
pco <- read_qza("unweighted_unifrac_pcoa_results.qza")
could be read in as
RPCA <- read_qza("ordination.qza")
if you are following the tutorial above.
