rblindlist error?

[rBatt]

Error in .Call("Crbindlist", l, use.names, fill) : 
  "Crbindlist" not resolved from current namespace (data.table)

Running data.table 1.9.6

I got the error when simply trying to print a data.table, not while creating it (even running str(dt) showed reasonable content). Subsequent function that tried to use dt did fail though, with similar error message.

I uninstalled, installed v 1.9.4, and the error was gone.

I haven't tried 1.9.7, and I haven't tried to isolate the error and make a minimal example. If this isn't a duplicate issue and it's an unresolved bug, I can post back with much more information.

Sorry for such a minimal tip-off. Once I got it working again I tied my system up with the work I was trying to do. But just let me know and I'll definitely report back with all the useful goodies :)

Thanks/ sorry

Were you able to reproduce the error after starting a new R session, before installing 1.9.4?

I've gotten similar odd errors that resolved upon restarting R. Haven't isolated a specific trigger, though.

[rBatt]

Frankly, I haven't tried to reproduce it yet. But sitting in 1.9.4 all week. And at this point, I can barely remember where it happened to me :( I'm not going to be upgrading to a higher version until #1371 gets fixed, because I need fread to work :(

@rBatt Can you post a reproducible example using any data.table version?

I had the same issue, but was unable to isolate it too deeply.
Quitting out my R Session and starting from a fresh, clean session resolved the issue.

It only occurred when printing out more than 100 rows of data, on any data.table, regardless of content. Even a simple DT <- data.table(A=1:1000, B='hello') had the same issue.
DT[1:100] would print fine (as would, any arbitrary 100 lines, ie DT[201:300])
But DT[1:101] would throw the error shown in the OP

Once I started the new session, I was no longer able to reproduce it.

When you come across it next time, without restarting the session use debugonce(data.table:::print.data.table) and try to isolate the issue..

Until then, I'm not sure if we can do anything about this.

Just hit the error again

Error in .Call("Crbindlist", l, use.names, fill) :
  "Crbindlist" not resolved from current namespace (data.table)

R> traceback()
6: rbindlist(l, use.names, fill, idcol)
5: data.table::.rbind.data.table(...) at <text>#1
4: rbind(deparse.level, ...)
3: rbind(head(x, topn), tail(x, topn))
2: print.data.table(x)
1: function (x, ...)
   UseMethod("print")(x)

Then in rbindlist(), it's right in the first line
debug: ans = .Call("Crbindlist", l, use.names, fill)

I saved the DT as an RDS object, quit the session, started a fresh session, loaded the RDS, and all was fine.

It must be something in the session, though I wasn't able to identify.
If no one else is able to reproduce, I would leave this issue as closed for now

Hi,

I hit this problem only when I use RStudio (0.99.887), but not in an R session started from a terminal.

R 3.2.3.

When I try to rbind an empty data.table with a one-line data.table, I get

source('~/work/rstatistics/bug_data.table.R')
Error in .Call("Crbindlist", l, use.names, fill) :
"Crbindlist" not resolved from current namespace (data.table)

Enter a frame number, or 0 to exit

1: source("~/work/rstatistics/bug_data.table.R")
2: withVisible(eval(ei, envir))
3: eval(ei, envir)
4: eval(expr, envir, enclos)
5: bug_data.table.R#26: rbind(aucs, myaucs)
6: rbind(deparse.level, ...)
7: #1: data.table::.rbind.data.table(...)
8: rbindlist(l, use.names, fill, idcol)

This happens after loading a 15Mb file. Source code+ file available on request.

Pushed a fix. Please write back if it's still not fixed.
