Strange issue while testing the Code #126

Closed nandofernandesneto closed 7 years ago

Hello everyone.

I've successfully created a google account to login with google trends from this application and at first glance, everything works fine.

But, when I run the following code snippet:

sport_trend <- gtrends(c("nhl", "nba", "nfl"))

I get the following error:

Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format

But still, If I do:

plot(sport_trend)

It plots the graphic correctly. Any idea of what does this error mean?

I've just realized that the plot command was working because the sport_trend data was included in the package ... If I change the variable name to "sport_trends" instead of "sport_trend", it won't work...

sport_trends <- gtrends(c("nhl", "nba", "nfl")) Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format

Maybe related to #96

If I set the Timezone to UTC, it works.

Sys.setenv(TZ="UTC") before running the code.

Thanks a lot for your attention.

Best Regards, Fernando Fernandes

PS: Congratulations for your initiative.

@nandofernandesneto Can you dl the dev version and see if it corrects the error?

PMassicotte commented 7 years ago

This is likely to be fixed in the upcoming version
