Hi, Could you let us know if you’re able to reproduce it in the devel version 1.9.3 as well?

Hi all, Sorry to resurrect an old thread, but I've been experiencing these problems too and have come up with a reproducible example (for me anyway). Data.table 1.9.2, R 3.1.0 I was trying to join some tables and got the usual "rerun with allow.cartesian=TRUE" message like Michele, and then got this error: Error in if (!is.null(lhs)) { : missing value where TRUE/FALSE needed However while I was trying to strip down my data to reproduce the error, I now consistently get this one instead: Error in `[.data.table`(x, y, `:=`(female, female)) : object 'bysubl' not found rather than the TRUE/FALSE one. But they seem to be related. * x has a column of subjects, some duplicated * y has a column of subjects, none duplicated, and some not present in x (all subjects of x are in y though). * y additionally has a binary column `female` that I wish to join into x (I know there are other ways to do this, but this is a stripped down example and seems to point out something going wrong in data.table so it is just an illustrative example): ``` library(data.table) x=fread('x.csv') y=fread('y.csv') setkey(x, subject) setkey(y, subject) x[y] # Error in vecseq(f__, len__, if (allow.cartesian) NULL else as.integer(max(nrow(x), : # Join results in 33 rows; more than 28 = max(nrow(x),nrow(i)). Check for duplicate key values in i, each of which join to the same group in x over and over again. If that's ok, try including `j` and dropping `by` (by-without-by) so that j runs for each group to avoid the large allocation. If you are sure you wish to proceed, rerun with allow.cartesian=TRUE. Otherwise, please search for this error message in the FAQ, Wiki, Stack Overflow and datatable-help for advice. x[y, female:=female] Error in `[.data.table`(x, y, `:=`(female, female)) : object 'bysubl' not found ``` I get the above reproducibly with this dataset. From now onwards, if I type in 'x' or 'y' into the prompt I get nothing printed at all. Additionally: ``` tables() # Error in gettext(domain, unlist(args)) : invalid 'string' value # Error: argument "finally" is missing, with no default ``` The only solution is to restart the R session. Note: this *doesn't* occur if the column I try to merge (`female` in this case) is continuous, for example. I can only get it if it's logical. I've attached x.csv and y.csv to this email for you to play with. I think it might be possible to strip down the tables to less rows (x has 28, y has 26) but in my (not exhaustive) attempts to do so, I didn't get this particular error. x.csv <http://r.789695.n4.nabble.com/file/n4692401/x.csv> y.csv <http://r.789695.n4.nabble.com/file/n4692401/y.csv> -- View this message in context: http://r.789695.n4.nabble.com/What-is-going-on-with-R-3-1-tp4689002p4692401.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
