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, Does anyone have experience using RJDBC library to write to Sybase datatable? The jdbc driver I am using is jConnect 6.0. I can successfully write into a new datatable, but have problem appending rows to existing one. It either complains "Table *** already exists" or simply overwrite the existing one. Here is the example. I am trying to append 'data' to the existing

...I create a multivariate time series containing NA values. I want to compute a linear regression and obtain a time serie for both residuals and fitted values. I have tried the trick ts.intersect, without success. Could you help me out of this? #### Example: y<-ts(1:10+rnorm(10)) x<-ts(1:10) datats<-cbind(y,lagx=lag(x)) Notice the datats could come directly from an imported file, that is why I did not use ts.intersect(y,lagx=lag(x)) fit<-lm(y~lagx,data=datats,na.action=na.omit) but how do I get a time serie of residuals instead of a vector residuals(fit)? ###### Matthieu Cornec

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, If given a dataframe (long form) with Year, Species, and Location, How would I write a function that would create a unique matrix of Species & Location for each Year? What I've tried doing is the following: data #dataframe dataT<-table(data$Species,data$Location,data$Year) #creates tables of Species vs Location for each Year But I'm encountering issues individually

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 <-

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. How can I get around this in clang? Thanks in advance! On Mon, Feb 25, 2013 at 7:14 PM, Ashi <ashi08104 at

Dear R users: I want to have in the same column both symbols, line and points, one for a data, and the other for the model. How can I do that? Or is there other better form to show both data and model in the same graphic? I need to make the difference on time of the same subject (repeated measurements on time) Problem example: ###########################################################

Hi, all. The previous post have a typo: 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. How can I get around this in clang? My problem is actually how to load external symbol in

Hi, I made a UserDSN using "wine control". Driver Mysql ODBC 5.1 Driver is installed under wine. I can connect to the Database. I want to connect to a table in that DB using Lotus Approach. After connecting I see only Datafields with INT values. All Fields with VARCHAR values are not displayed. In the UserDSN configuration window I changed the charset option of the Mysql ODBC Connector

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

Hi, I am trying to show an interquartile range while grouping values using the function ddply(). So my function call now is like groupedAll <- ddply(data ,~groupColumn ,summarise ,col1_mean=mean(col1) ,col2_mode=Mode(col2) #Function I wrote for getting the mode shown below

Hi, Bernie, Thanks for your reply! However, I still have problem by following edk2's code, my test code is attached, what I want to do is build it as a dynamic lib. But I get error from ld: ld: illegal text-relocation to _data_table in table.o from foo in use_table.o for architecture armv7 Do you have any suggestion to solve this? Thanks! //==begin table.c== int data_table[] = {0xff, 0xff};

Hi, I recently discovered the R program and I thought it could be useful to me. I have to analyse data saved as .Px file (x between 0 and 8 - .P0 files have 18 lines at the beginning that I have to skip). New files are generated everyday. This is my strategy : In order to analyse the data, I first want to copy the new data in a database in MySQL (which already contains the previous data). So
