Within R, I am using the package gtrendsR. On the web version of google trends, one can "combine" search terms by putting plus signs between them as follows:
I believe this effectively makes the search term apple+orange a kind of sum of both of these search terms. I know one could write multiple separate search terms within gtrendsR, such as gtrends(c("apple", "orange")
, but this is not what I want to do.
Is there any way to perform the same operation shown in the picture (apple+orange) with the gtrendsR package? I have been unable to figure out how to do this.
What have you tried?
> library(gtrendsR)
> res <- gtrends("apple+orange")
> plot(res)
yields pretty much your answer (modulo different time resolution which you can adjust).
