gtrendsR provides an interface for retrieving and displaying Google Trends information.
Trends (number of hits) over time as well as geographic representation of the results can be displayed.
Due to recent changes to Google Trends API, the CRAN version of the package is no longer working. If you wan to continue to query Google Trends, you have to install the development version of the package. This will be soon deployed on CRAN.
In this simple example, trends for keywords
nba are retrieved for Canada and USA and then plotted from R.
library(gtrendsR)res <- gtrends(c("nhl", "nba"), geo = c("CA", "US"))plot(res)
Since release 1.3.0, the package is on CRAN and can be installed via
Release-candidate packages are available in the ghrr drat repository and can installed via
install.packages("drat") # easier repo access + creationdrat:::add("ghrr") # make it knowninstall.packages("gtrendsR") # install it
Development version (which may be less stable) can be installed directly from this repository via
if (!require("devtools")) install.packages("devtools")devtools::install_github("PMassicotte/gtrendsR")
