gtrendsR 1.3.3

A very nice new update to the gtrendsR package by Philippe and myself is now avilable via CRAN. I had only blogged about the initial 1.3.0 release, and we have added a whole slew of new features and fixes. Philippe rewrote a lot of the parsing to make it more robust to different encodings, and to add other features. So in no particular order, we can now sub-group by regions more finely, withstand various misfeatures in returned data sets, generally do better on connections, and more — and also allow for intra-day, daily and weekly queries!

That last part is pretty fun. Here is the code I ran last Saturday to look at the query for Donald Drumpf, a name brought to us via a beautiful John Oliver episode worth watching which ran about nine days ago. So last Saturday, when we were still within the seven day window, I ran

library(gtrendsR)
dp <- gtrends("Donald Drumpf", res="7d")
plot(dp) + ggplot2::ggtitle("The Drumpf") + ggplot2::theme(legend.position="none")

which resulted in the following chart

which highlights another nice feature: the ggplot2 object created by the plotting function is returned, so we can locally modify and tune it. Here we set a title and suppress the default legend.

As I had not blogged about the interim bug-fix releases 1.3.1 and 1.3.2, here is the set of NEWS entries for the last three releases:

gtrendsR 1.3.3

• A ggplot2 object can now be returned for further customization. plot(gtrends("NHL")) + ggtitle("NHL trend") + theme(legend.position="none")

• Support for hourly and daily data (#67). For example, it is now possible to have hourly data for the last seven days with gtrends("nhl", geo = "CA", res = "7d"). Use ?gtrends for more information about the time resolution supported by the package.

• Support for categorties (#46). Ex.: gtrends("NHL", geo = "US", cat = "0-20") will search only in the sport category.

• Some countries (ex: Hong Kong) were missing from the list (#69).

• Various typos and documentation work.

gtrendsR 1.3.2

• Added support for sub-countries (#25). Ex.: gtrends("NHL", geo = "CA-QC") will return trends data for Québec province in Canada. The list of supported sub-countries can be obtained via data(countries).

• Data parsing should work for any data returned by Google Trends (i.e. countries independent).

• Better support for queries using keywords in different languages (#50, #57). Ex.: gtrends("蘋果", geo = "TW")

• Now able to specify up to five countries (#53) via gtrends("NHL", geo = c("CA", "US"))

• Fixing issue #51 allowing UK-based queries via geo = "GB"

gtrendsR 1.3.1

• Fixing issue #34 where connection verification was not done properly.

• Now able to use more latin character in query. For example: gtrends("montréal").

• Can now deal with data returned other than in English language.

Courtesy of CRANberries, there is also a diffstat report for the this release. As always, more detailed information is on the gtrendsR repo where questions, comments etc should go via the issue tickets system.
