Description

Search results on a keyword over all fields in PLoS Journals.

  stop("need an API key for PLoS Journals")), curl = getCurlHandle(),
  callopts = list())

Arguments

visualize results in bar plot or not (TRUE or FALSE)

key

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

callopts

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)

Examples

plosword('Helianthus')
plosword(list('monkey','Helianthus','sunflower','protein','whale'),

out <- plosword(list('monkey','replication','design','sunflower','whale'),
   vis = TRUE)
out[[1]] # results in a data frame
out[[2]] # results in a bar plot

# Pass in curl options
plosword('Helianthus', callopts=list(verbose=TRUE))
