Hi I followed a railscast episode and got datatables up and running, beautifully along with the nice jquery-ui as in the front page. The main issue I''m having though is that I suck at CoffeeScript/JS ~_~ I''m trying get the datatables to reload every 1 second but I don’t see any request coming into my webserver for refreshes and hence, no refreshes on the web page itself.

Hi, We are working on a project on forecast modeling and would like to know if there are any examples on how to READ/WRITE to a database (e.g. PostgreSQL) using R-Project. I do have a sample R Script which takes input as files from a directory and writes back output files to a directory. I would like to convert this script to read from a database and write back the output to a database.

Hi, I've added R_init_data_table to the "data.table" package (which has a dot in its name). This works well in R 2.15.0, because of this from the Writing R Extensions manual : " Note that there are some implicit restrictions on this mechanism as the basename of the DLL needs to be both a valid file name and valid as part of a C entry point (e.g. it cannot contain ?.?): for

Hi, all. Another problem in ARM assembly: I use LDR to load an external symbol : LDR R7,=DataTable But clang gives error: unexpected token in operand to the '=', Then I change the code to: LDR R7,=DataTable The error becomes: unsupported relocation on symbol.

Dear R experts, I would really appreciate if you had an idea on how to use more efficiently the aggregate method: More specifically, I would like to calculate the mean of certain values on a data frame,? grouped by various attributes, and then create a new column in the data frame that will have the corresponding mean for every row. I attach part of my code: matchMean <-

Here is the example. I am trying to append 'data' to the existing

Hi Ashi, Your first LDR is a pseudoinstruction that is supported by some tools (gas and armasm, at least), but not by LLVM. Roughly speaking, it turns into a PC-relative load from a literal pool. To do what you're trying to achieve you can write your own literal pool in your assembly. You can see some examples of this sort of thing at
