renaming Samples after import

[splaisan]

My sample file names are very long and make ugly plot axes. can I plot using a different metadata column for names (eg sample_id or paste0(group, "-", replicate) from the metadata below or rename the samples after import?

> mydata$meta
# A tibble: 6 x 5
  Sample                    sample_id  tcr   group replicate
  <chr>                     <chr>      <chr> <chr>     <dbl>
1 SRR7518747.clonotypes.TRB SRR7518747 B     SHAM          1
2 SRR7518748.clonotypes.TRB SRR7518748 B     SHAM          2
3 SRR7518749.clonotypes.TRB SRR7518749 B     SHAM          3
4 SRR7518754.clonotypes.TRB SRR7518754 B     MI            1
5 SRR7518755.clonotypes.TRB SRR7518755 B     MI            2
6 SRR7518756.clonotypes.TRB SRR7518756 B     MI            3

thanks
