I'm having trouble using the code below in Google Scholar. The double quotation marks around "data availability" aren't appearing in the search query. Does anyone have any solutions for this problem?
r script
search_pre="(\"osf.io\" OR \"data availability\")"
journal=paste(" source:'","The Proceedings of the National Academy of Sciences","'",sep="")
search<-paste('https://scholar.google.com/scholar?hl=en&q=',search_pre,journal,sep="")
browseURL(search)
# I also tried the following scripts, also doesn't work
search_pre="('osf.io' OR 'data availability')"
journal=paste(" source:'","The Proceedings of the National Academy of Sciences","'",sep="")
search<-paste('https://scholar.google.com/scholar?hl=en&q=',search_pre,journal,sep="")
browseURL(search)
