Not a fix, but I always found xlsx to be a memory hog. I find the readxl package strictly dominant, especially with the much-improved latest release.

You are right , I also ended up using readxl at the end. Solved a big headache. Worst case is debugging this issue to figure out that it is due to such a package load. Because this error comes inside a code which has no relation with xlsx package and hence no one would suspect it.

i agree, and it should be investigated in case there's something less idiosyncratic about the issue. glad you found readxl and it works

@niths4u I can't reproduce with data.table 1.10.5 (built 2017-09-28 22:35:08 UTC) on R 3.4.1/OSX El Capitan 10.11.6

Can you try installing the current development version (see here) & try again? If there's still an error, try restarting your machine to run from a fresh session. If the bug still persists, please provide more details about your setup, including your sessionInfo().

Hi,
i am not able to reproduce on latest development version 1.10.5 on R 3.3.2. I guess this can be closed now.

Also just to note few more observation to help other readers who face the same issue

1. R 3.3.2 - data.table 1.10.4 fails
2. R 3.4.2 - data.table 1.10.4 works ( but note that this has all other packages including xlsx and xlsxjars updated)
3. R 3.3.2 - data.table 1.10.5 works
4. R 3.4.2 - data.table 1.10.5 works

Thanks

thanks for the report! feel free to follow up if there's some regression.
