Arguments

physeq

(required): a phyloseq-class object obtained using the phyloseq package.

path

a path to the folder to save the phyloseq object

rdata

(logical) does the phyloseq object is also saved in Rdata format?

one_file

(logical) if TRUE, combine all data in one file only

write_sam_data

(logical) does the samples data are add to the file. Only used if one_file is TRUE. Note that these option result in a lot of NA values.

sam_data_first

(logical) if TRUE, put the sample data at the top of the table Only used if one_file and write_sam_data are both TRUE.

clean_pq

(logical) If set to TRUE, empty samples are discarded after subsetting ASV

reorder_asv

(logical) if TRUE the otu_table is ordered by the number of sequences of ASV (descending order). Default to TRUE. Only possible if clean_pq is set to TRUE.

rename_asv

reorder_asv (logical) if TRUE, ASV are renamed by their position in the OTU_table (asv_1, asv_2, ...). Default to FALSE. Only possible if clean_pq is set to TRUE.

remove_empty_samples

(logical) Do you want to remove samples without sequences (this is done after removing empty taxa)

remove_empty_taxa

(logical) Do you want to remove taxa without sequences (this is done before removing empty samples)

clean_samples_names

(logical) Do you want to clean samples names?

silent

(logical) If true, no message are printing.
