I am trying to log into my Google account in R using gconnect() in the gtrendsR package, but am running into issues. I have been doing research using Google Trends data for the last month, and have never had a problem with this.
Please let me know if you have any thoughts. I had Google Support take a look at my account to see if there were any holds or something, but nothing showed up. Also tried logging in through another account which didnt work..
This is what I am trying to do:
usr <- 'my_username@gmail.com'
psw <- 'my_password'
gconnect(usr, psw)
And then I am returned with the following error:
Google login failed! Check your login information.NULL
It seems there is no quick solution for gtrends. However, I discovered a URL which directly downloads the data.
This url is the link of 'download as csv' menu in Google Trends. However, direct fetching from R by download.file function is problematic.
See this page: https://www.google.com/settings/security/lesssecureapps. Try switching to "on" if the setting is "off".
Log into your Google Account again and check if it works now. I had the same problem but miraculously everything works again today. It seems to me as if Google sometimes moves accounts into some sort of quarantine state and releases them after a while.
