Webscraping with R JSON

Question

I want to get the names of the companies by two columns Region and Name of role-player. I find json links on each page already, b

Answer 1

My personal preference for this is to use the library jsonlite and not use fromJSON at all

require(jsonlite)
data<-jsonlite::fromJSON(raw_data, simplifyDataFrame = TRUE)
finalData<-data.frame(cbind(data$rolePlayers$RolePlayer$orgName, data$rolePlayers$Region$RegionNameEng))
colnames(finalData)<-c("Name", "Region")  

Which gives you the following data frame:

                                   Name       Region
                GoodHope Cheese (Pty) Ltd Western Cape
                       Jay Chem (Pty) Ltd Western Cape
                Coltrade International cc Western Cape
 GC Rieber Compact South Africa (Pty) Ltd Western Cape
                    Latana Cheese Pty Ltd Western Cape
                       Marco Frischknecht Western Cape

A great way to visualize how to query and what is in your JSON string can be found here:Chris Photo JSON viewer

You can just cut and paste it in there from the raw_data (removing external quotation marks). From there it becomes easy to see how to structure your data using addressing like you would with a traditional data frame and the $ operator.
