Is there anyway I can write a script which feed input datasource from stdin and let R process it (maybe frequency report) then output the report to stdout? I can't seem to find much info on documentation or FAQ on this topic. Thanks!

Hello.. I am pretty new for R, but if I understand it correctly, when R read data by doing something like "d <- read.table("/dev/stdin")", it read entire data first then start processing.. Is there anyway I can tweak R around so that it will start processing as data comes and not load everthing on memory at once? The reason for this is because we have a case where

Hello list, I've been having a tough time adding windows resource support to my ogg vorbise decoder, although I think I am close. Basically when I call ov_open_callbacks(), it doesn't ever return and repeatedly calls my seek_func. I'm hoping it is something obvious, but I can't see why my seek_func is being called endlessly. If the file is seekable, I should return 0, right? If

Dear all, I have a different data sets and I am doing some calculations over time, For that every data set is split into junks based on the time stamps so one data set has like 10 timestamps. There is also the case that one data set has less than 10 timestamps. In my code I was doing the following lapply(Datasource,analysis_for_one_data_source)

Hi, I have two dataframes that have some common columns. I would like to join them by the common columns prochi and prescribed_date as there are duplicate prochis but they will be made unique by date. I tried doing an inner join but that just duplicated the columns whereas I would like the information from the test_sql_tsf to fill the NAs in the test_sql_psd common columns. require(sqldf)

I have been searching for the last two days and I cannot seem to set Asterisk to work from a database, can someone please tell me what I am doing wrong here?

Hello, I am closely following the RTAQ documentation in order to load my dataset into R, however I get this warning when running the convert function in the following way: convert(from="2010-11-01", to="2010-11-01",datasource=datasource, datadestination=datadestination,trades=T,quotes=T,ticker="BAC",dir=T, extention="csv", header=T,

I keep expecting R to have something analogous to the =count function in Excel, but I can't find anything. I simply want to count the data for a given category. I've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density),

I would like to use puppet classes to inject and/or replace xml elements into an existing xml configuration file. This seems to me to be a common problem already solved. Can anyone suggest the easiest way to do this? An example use case would look like something like this. Given xml file: <host> <server name="one"/> <server name="two"/>

I'm trying to add cdr_odbc.so to log my CDR data to a mysql DB. I've managed to compile everything, and seem to almost be ready to head home. I've added a small debug line to cdr_odbc.c as follows: if((ODBC_res != SQL_SUCCESS) && (ODBC_res != SQL_SUCCESS_WITH_INFO)) { if(option_verbose > 10) ast_verbose(

Hi all, I'm very new to Ogg, and am learning about it in an attempt to stream it from a CF card through a microcontroller. This particular setup requires me to move parts of the file from the CF card to the microcontroller buffer, effectively making the file like a data stream. Also, should this question be directed at the Tremor group instead since that is the codec I'm using? It

hello, i am new to R and want to use it for a small project to draw a wind data from a microclimate datasource, can someone give me an example of how i can represent this in a neat way? for example, i have: speed, direction 0.3,NNE 0.45,NNE 0.32,NE 0.28,N 0.30,NE how do i put this data to get a windrose graph? many thanks norman -- %>>> "".join( [

Starting on friday I download icecast 2.3.2 and compiled it on SLES10. Very soon I was able to use ices to stream an mp3 file to a mp3 (phonostart, foobar) client via Icecast. But my flashplayer, which was able to get streams from icacast1, was not able to full fill his job. I did reseaches on the net, hour for hour, found a lot of stuff. Also some changings in format_mp3.c. But with no success.

Hi, is cdr logging using odbc buggy? I'im only getting an error "cdr_odbc.c:174 odbc_log: Unable to retrieve database handle. CDR failed.". Connecting with isql to the datasource given in cdr_odbc.conf works just fine, and using the database for sippeers also works. The documentation[1] is confusing because it says freeTDS is required and that you must not use multiple

Hi, dovecot provides POP and IMAP services. Proposal: Would be nice if it also could offer an RSS-Feed for a mailbox, giving a summery of sender/subject/date and maybe the first lines of text. regards Hadmut

Hi, I can't figure out how to get the P-values out of the summery of a logistic regression. I used: logit.out <- glm(...) and then I should be able to extract just the P values for the coefficients. Any idea? Kris -- ------------------------------------------------------------------------ http://perswww.kuleuven.ac.be/~u0027178/VCard/mycard.php?name=krisn

How can I see my codes (syntax) after restoring a workspace? Also " Summery" tnx Mike [[alternative HTML version deleted]]

Morikawa-san, Your conf is wrong. Should be: quota_warning = storage = 95 %% quota-warning 95 %u Your conf: quota_warning = storage = 95 %% quota-warning 95% u There's a space between % and u. First of all, try the above and let us know if it changes. Kouga -----Original Message----- From: ????? <morikawa-k6 at itec.hankyu-hanshin.co.jp> Sent: Wednesday, October 28, 2020

Greetings, I was wondering if anyone on this list has any experience using Ruby/Rails with either DB2 or SQLServer. We''re currently in the later planning stages of two RoR applications and I''m not 100% sure about the state of these two drivers. Googling for this information locates multiple sites that discuss various driver implementations (DBI, etc) for both databases.
