This article shows with example how to analyze Google Trends data in R programming languages. The R package gtrendsR is used in this article for analyzing the google trends data.

The gtrendsR Package

The gtrendsR Package is built for retrieving and displaying the information from Google Trends.

Let's install and load the package:


Now, let's check the main arguments of the package:

  • keyword: A character vector for specifying query keywords. For example, c("python", "java")
  • geo: A character vector of geographic regions. For example, c("ES") (default value is "all" for worldwide).
  • time: A string for specifying the time span of the query. For example, "now 3-H" (last three hours), "now 7-d" (last seven days), "today 3-m" (last three months), "today+5-y" (last five years) (default value), "all" (all since 2004), or 2015-01-01 2016-12-30 (time span between two dates).
  • gprop: A character vector for specifying Google product or service to perform trend query. For example, c("web", "news", "images", "froogle", "youtube") (default value is "web").
  • category: A character for specifying the character (default value is "0").
  • hl: A string for specifying language code. For example, "es-ES" (default value is "en-US")
  • lower_search_volume: A logical value for specifying whether to include lower search volume regions or not.

Google Trends Analysis Example

Let's compare Python and Java in Google Trends for the last five years over the world, and see the relative interest over time between them in a plot.


trends <- gtrends(keyword = c("python", "java"))

# select only interest over time
time_trend <- trends$interest_over_time

# display the plot
plot_line <- ggplot(data = time_trend, aes(x = date, y = hits, color = keyword)) +
  geom_line() +
  labs(title = "Python vs Java",
       subtitle = "A Google Trends Report",
       x = "Time",
       y = "Relative Interest")

line plot

Ending note

Hope, this will help you to explore Google Trends data analysis in R using gtrendsR Package.

Happy R coding!
