search for: subindex

...cuments, like you would expect. So far all good. Here is the problem: when I search through the indexes together (using database_add_database() on each sub-index), all the document_id:s are numbered globally, so it seems while writabledatabase_add_document() reset the document_id counter for each subindex, in the subindexes they were never reset. So instead of having 10 sub-indexes with 50 documents in each, document_id:s ranging from 0-50 in each, I seem to end up with 10 sub-indexes with 50 documents in each, document_id:s ranging from 0-49 in subindex 1, 50-99 in subindex 2, and so on. This woul...

...t I need to get is a data frame like the one below - cities as rows, brands as columns, and the sums of the "value" within each city/brand combination in the body of the data frame: city x y z a 3 23 336 b 7 42 231 I have written a code that involves multiple loops and subindexing - but it's taking too long. I am sure there must be a more efficient way of doing it. Thanks a lot for your hints! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

...c(NA,1,NA,1,NA),c3=c(NA,NA,1,NA,NA)) I know how to do it with a loop that runs through rows of mydf. However, in real life I have a huge data frame with tons of rows, dozens of columns (instead of 3 in this example) - I am afraid it'll take forever. Any hint on how to do it faster, maybe using subindexing somehow? Thank you very much! -- Dimitri Liakhovitski [[alternative HTML version deleted]]

Hi, I'm trying to use expression() to write a text to a graphic in the margin. Using: mtext(expression(beta),side=1,line=2) writes a perfect beta greek character, but I need to add a subindex "max", and I'm trying: mtext(paste(expression(beta),"max"),side=1,line=2) simply writes "beta max" in the plot. Please, Could you tell me what I'm doing wrong? By the way, is there a way to add Latex expressions to graphics? Then I could use the Latex expre...

Greets, When merging lots of subindexes in batches like so: xapian-compact -m idx1 idx2... dstidx Errors such as: xapian-compact: DatabaseError: Error reading block 0: got end of file present a problem since it does not provide the offending path name (of the broken index) for easy identification/removal in automated/batch scenario...

I have an app that has two models -- products and details. I''m building a form that allows a user to create a new product and specify a description, etc. The form needs to allow for creation of multiple items in the details model/table. for example, I have a block of form items that collect info for the men''s version of the product -- inventory count for each size, etc. And
