Base function to search PLoS Journals

Usage

searchplos(terms = NA, fields = NA, toquery = NA, start = 0, limit = 1000, url = "http://api.plos.org/search",
  key = getOption("PlosApiKey", stop("need an API key for PLoS Journals")), ...,
      curl = getCurlHandle())

Arguments

terms

search terms (character)

fields

fields to return from search (character) [e.g., 'id,title'], any combination of search fields [type 'data(plosfields)', then 'plosfields']

toquery

list specific fields to query (if NA, all queried)

start

record to start at (used in combination with limit when you need to cycle through more results than the max allowed=1000)

limit

number of results to return (integer)

url

the PLoS API url for the function (should be left to default)

key

your PLoS API key, either enter, or loads from .Rprofile

...

optional additional curl options (debugging tools mostly)

curl

If using in a loop, call getCurlHandle() first and pass the returned value in here (avoids unnecessary footprint)
