I finally managed to upgrade to 1.5.3, but now I'm seeing errors when aggregating data tables:
> d <- data.table(a=as.integer(c(1, 1, 2, 2, 3, 3)), b=1:6 %% 2, c=1:6) > d[b==1,list(c=sum(c)),by=list(a)] Error in i[1, ivars, with = FALSE] : incorrect number of dimensions Does anyone know what's going on with this? Thanks, Johann _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
