First, install the functions by pasting this code into R.
You now have the following functions at your disposal:
- URL_GT(keywords)
- downoloadGT(url, downloadDir)
- readGT(file path)
#downloadDir=Where you save the csv from Google Trends
downloadDir="C:/downloads"
setwd(downloadDir)
keywords=c("Samsung", "Apple", "Nokia")
url=URL_GT(keywords)
filePath=downloadGT(url, downloadDir)
smartphones=readGT(filePath)
library(ggplot2)
ggplot(smartphones, aes(x=Date, y=SVI, color=Keyword))+geom_line()

Thanks for the interesting post. Unfortunately, when I tried to use with my R version 3.0.2 it gave me the following error:
"Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'report.csv': No such file or directory"
It is somewhat strange since the report.csv is correctly downloaded in the specified "downloadDir" directory, but it is unable to open it.
Thanks for the help.
Best regards, Dean
Hi Dean,
You need to set your download directory as your working directory by entering the following:
setwd(downloadDir)
Then it should work. Let me know if that doesn't help!
