get_realtime function

[XD-DENG]

I tested function get_realtime with codes below

while (TRUE){
  print(print(get_realtime("*******")))
  Sys.sleep(3)
}

If there is no visitor currently on my website, this code returns

No results were obtained.
NULL
NULL

which makes sense (and the while loop keeps running well).

But once these is any visitor, I got error as

Error in `colnames<-`(`*tmp*`, value = character(0)) : 
  attempt to set 'colnames' on an object with less than two dimensions

I may look into this issue myself later and build a pull request after I figure it out (if I'm lucky enough ;-))

get_realtime(id) works fine for me with or without active users.

> while (TRUE){
+     print(get_realtime(id))
+     Sys.sleep(3)
+ }
  active.users
1          120
  active.users
1          121
  active.users
1          121

Do you try the latest dev version? Can you provide full traceback()?

Hi Artem, below is the traceback I got.

Just like what happened previously, the error appeared when the site is visited (from "No visitor" status).

+ print(get_realtime("******"))
+ Sys.sleep(3)
+ }

What version are you using? Please try the dev version: devtools::install_github("artemklevtsov/RGA").

[XD-DENG]

I'm using latest version 0.2.4 on CRAN, with R 3.2.2 and Mac OS.

Let me try the dev version and check if this bug is still there. Will let you know then.

[XD-DENG]

Tried the dev version and the dev version works well for this function. Good job.

Thank you for the feedback.

I had the same problem, but your dev version works nicely
