continue ncbi_downstream() for loop even when one taxon generates error? #923
Description
I am trying to retrieve NCBI taxids for all genomes in a particular phylum. It seems that downstream() only works for one level below the given taxid, so I wrote some for loops to collect the information from each subsequent taxonomic level. When I get to the species level, I get "Error: Bad Request (HTTP 400)" and I can link this to a small number of specific species.
Is there a way to ensure the taxids still get downloaded for the downstream() taxa of interest, even if some of them generate the error? My code is below along with the final error and session info.
phylum = "Mollusca"
phy_ids <- as.data.frame(get_ids(phylum, db='ncbi')$ncbi)[1]
class_ids <- ncbi_downstream(id=phy_ids[1], downto="class")$childtaxa_id
order_ids <- list()
for (x in class_ids) {
orders_tmp <- ncbi_downstream(id=x, downto="order")
order_ids <- append(order_ids, list(orders_tmp))
}
family_ids <- list()
for (x in order_ids) {
fam_tmp <- ncbi_downstream(id=c(x$childtaxa_id), downto="family")
family_ids <- append(family_ids, list(fam_tmp))
}
genus_ids <- list()
for (x in family_ids) {
gen_tmp <- ncbi_downstream(id=c(x$childtaxa_id), downto="genus")
genus_ids <- append(genus_ids, list(gen_tmp))
}
species_ids <- list()
for (x in genus_ids) {
spp_tmp <- ncbi_downstream(id=c(x$childtaxa_id), downto="species")
species_ids <- append(species_ids, list(spp_tmp))
}
Error: Bad Request (HTTP 400)
