Dear List, I'm trying to use R under Windows on a huge database in MySQL via ODBC (technical reasons for this...). Now I want to read tables with some 160.000.000 entries into R. I would be lucky if anyone out there has some good hints what to consider concerning memory management. I'm not sure about the best methods reading such huge files into R. for the moment I spilt the whole

Dear Group, if anyone has experience with the RMySQL Package maybe this behaviour is know: Reading data from a table into R the fields with datatype bigint(20) unsigned are transformed in some way: e.g. the query "select * from orders where userid = 14929859848712890325" selects the correct case but in R the userid is changed to 14929859848712890368. What happened here? This

Dear Group I'm still trying to bring many data into R (see older postings). After solving some troubles with the database I do most of the work in MySQL. But still I could be nice to work on some data using R. Therefore I can use a dedicated Server with Gentoo Linux as OS hosting only R. This Server is a nice machine with two CPU and 4GB RAM which should do the job: Dual Intel XEON 3.06 GHz

I have some time series data like 01/02/1990 0.531 0.479 01/03/1990 0.510 0.522 01/06/1990 0.602 0.604 there is no weekends and holidays. how do I graph them in a single plot that the x-axis is the dates and the y-axis is the time series?

In my (limited) experience R is more powerful concerning data manipulation. An example: I have a vector holding a user id. Some user ids can appear more than once. Doing SELECT COUNT(DISTINCT userid) on MySQL will take approx. 15 min. Doing length(unique(userid)) will take (almost) no time... So I think the other way round will serve best: Do everything in R and avoid using SQL on the database...

Dear List, I have two data.frame of the following form: A: n V1 V2 1 12 0 2 10 8 3 3 8 4 8 4 6 7 3 7 12 0 8 1 0 9 18 0 10 1 0 13 2 0 B: n V1 V2 1 0 2 2 0 3 3 1 9 4 12 8 5 2 9 6 2 9 8 2 0 10 4 1 11 7 1 12 0 1 Now I want to merge those frame to one data.frame with summing up the columns V1 and V2 but not the column n. So the result

Hi all, I'm testing Linksys SPA922 phone and I have strange issue. when call is finished on the phone I see "CallEnded" and normal silence for cca. 5 seconds and then I get fast busy for cca. 20 sec. So, this isn't automatic hangup as on other phones I have tried (Cisco 7940, grandstream, XLite,... ) and I have to manually hangup handset to finish a call. Is this normal behavior

Hi all, I have a question regarding using T38 for fax sending and here is my scenario: fax -> SIP ATA (T38 enabled) -> Asterisk #1 -> IAX TRUNK -> Asterisk #2 -> SIP ATA (T38 enabled) -> fax My question is, how can I know if I'm really using T38? is T38 information coming to the other side (because of SIP to IAX conversion) or just plain g711a data? I'm using Linksys

Hi all, I have a question regarding connection of two Asterisk servers to our PBX. Each Asterisk server has one PCI E1 card, and they are in failover mode with Linux HA. On our PBX we have only one E1 card towards Asterisk servers. My question is how to connect these two Asterisks to one E1 card on PBX, and when primary Asterisk server fails not to have to manually pull out E1 cable from primary

Hi there, I am wondering if it is possible to do an xyplot with two y-axes. I'd like to print two parameters in a time series but they both have different scales. Which parameter in xyplot can I add to achieve this result? Thanks a lot for any help. Antje [[alternative HTML version deleted]]

Dear group, First I provide you with an example, I found in the newsgroup. Then I'd like to explain my problem to you by means of the output. enviro <- data.frame(Year = rep(2001:2002, each = 365), Day = rep(1:365, 2), Precip = pmax(0, rnorm(365 * 2)), Temp = 2 + 0.2 * rnorm(365 * 2)) xyplot(Precip + Temp ~ Day | Year,

Hi all, I have a problem with using remote MySQL database server with two Asterisk (1.4.17) servers. PhoneA registers with Asterisk#1 using realtime into MySQL on remote server and everything is working fine and when I call Phone A from Phone B (also registered with Asterisk#1) call is established. Problem is when I call PhoneA (which is registered with Asterisk#1) from PhoneC (which is

Hi all, I have a question concerning xyplot. My data is a data.frame looking like that: In the first column I have numbers from 0 to 23 (hours of a day), the second column contains the name of a weekday (Day as factor) and the third column contains the number I am interested in. So as an example, the first five rows look like that: Hour Day Freq 1 0 Mo 23 2 1 Mo

Hi there, I have a question, which I thought is very easy to solve, but somehow I can't find a solution. Probably someone could help me quickly?

hello list, I'm trying to write a script that will search through a directory of trace logs for an oracle database. From what I understand new files are always being created in the directory and it's not possible to know the exact names of the files before they are created. The purpose of this is to create service checks in nagios. Because you don't know the names of the files ahead

Anyone used ETS Corporation''s EMoney ECOM Gateway ? I''m working on a project that will have to interface to it and if the work has already been done was hoping not to re-invent the wheel. Failing that, which payment gateway gem option is better - ActiveMerchant or Payment, or are there others ? I''m willing to add the work done for this to whichever option we use in
