Facebook collection - no posts found

[vosonlab]

The following test Facebook collection that we use in SocialMediaLab teaching materials (see e.g. here) is failing:

g_bimodal_facebook_csg <- Authenticate("Facebook",
appID = appID, appSecret = appSecret) %>%
SaveCredential("FBCredential.RDS") %>%
Collect(pageName="StopCoalSeamGasBlueMountains", rangeFrom="2015-06-23",
rangeTo="2015-07-23", writeToFile=TRUE) %>%
Create("Bimodal")

It iterates through the days (as per normal) but then fails with:

Error. No posts found for this date range! Please try a larger range.Error. Cannot create bimodal network using this type of data (see help file for data types and sources).
Error in class(networkToReturn) <- append(class(networkToReturn), c("SocialMediaLab")) :
attempt to set an attribute on NULL

Another user has reported similar problem.

This is using SocialMediaLab_0.23.0 and Rfacebook_0.6.11 (both current versions).

There may have been change in Facebook API?

This was just tested with SocialMediaLab_0.23.0 (CRAN version) and latest CRAN version of Rfacebook (0.6.15 - published 2017-05-25) and it now works. So it seems that there might have been a change to Facebook API regarding authentication which broke Rfacebook and it has been fixed in the latest version.

I am closing this issue as it appears to be solved.

Sorry but I have the same issue and It doesnt work for me, even with this version. How can I solve it?

[rjackland]

Please see #29 - unfortunately, changes to the Facebook API mean that we can't collect data from FB fan pages any more.

Also please note that SocialMediaLab has been renamed vosonSML (which is now on CRAN) and so SocialMediaLab will no longer be developed.
