how to get more than 100 entries when using entrez_search #151

Hi,

I'm using this package and I didn't figure out how to get more than 100 entries when using entrez_search. I tried removing the retmax argument but it didn't work.

Thanks a lot for your help.

Hi @HediaTnani,

You can change the value of the retmax parameter. For example:

library(rentrez)

entrez_search(db = "pubmed",
              term = "platypus",
              retmax = 200
)
#> Entrez search result with 773 hits (object contains 200 IDs and no web_history object)
#>  Search term (as translated):  "platypus"[MeSH Terms] OR "platypus"[All Fields]
