Error when using parse_tax_data function

[emankhalaf]

I have a feature table with taxonomy collapsed to the genus level, where the first column is the taxonomy (ranks separated by ;), then the rest of columns represents samples_id showing the read count of each feature. I need to split the taxonomy column into 6 taxonomic ranks using parse_tax_data function.
I used this code:

obj <- parse_tax_data(feature-table-with-taxonomyl6,
                      class_cols = "taxonomy",
                      class_sep = ";",
                      class_regex = "^([a-z]{0,1})_{0,2}(.*)$",
                      class_key = c("tax_rank" = "taxon_rank", "name" = "taxon_name"))
print(obj)

then I got this error:

Error in parse_tax_data(feature - table - with - taxonomyl6, class_cols = "taxonomy",  :    could not find function "parse_tax_data"

However, I already loaded taxa package but I have a problem when installed devtools.

Thanks!

This function is now in metacoder, although something like it might be in taxa again eventually. I have created an issue in the metacoder repo here: grunwaldlab/metacoder#334
