I am using R2.6.0 on “Windows Small Business Server 2003”. I apologize if the answer to my question is available…I have searched but have not found anything that I thought helped me. I have a dataframe that contains ~4.5 million rows and 5 columns. (see memory and df details below). I am trying to save the dataframe to a MS SQL Server database, using the “sqlSave” function. The code

Hi, I am trying to assign "Season" values to dates depending on when they occur. For example, the following dates would be assigned the following "Season" numbers based on the "season" intervals detailed below in the code: ddate Season 29/12/1998 20:00:33 1 02/01/1999 05:20:44 2 02/01/1999 06:18:36 2 02/02/1999

HI all, My I am trying to convert character date (mm/dd/yy) to YYYY-mm-dd date format in one of the columns of my data file. The first few lines of the data file looks like as follow head(Atest,10);dim(Atest) ddate 1 19/08/21 2 30/04/18 3 28/08/21 4 11/10/21 5 07/09/21 6 15/08/21 7 03/09/21 8 23/07/18 9 17/08/20 10 23/09/20 [1] 1270076 1 I am using the following

Hi list, I'm sure the explanation must be laughably simple to the experts out there, but I just could figure it out. I have a simple data frame that looks like, >head(da.off) DDate OffP 1 2005-01-01 41.23 2 2005-01-02 44.86 3 2005-01-03 44.86 4 2005-01-04 43.01 5 2005-01-05 45.47 6 2005-01-06 48.62 where the first column DDate currently is character, and OffP is numeric. I want

Hi, I am trying to install an application under wine 1.2 on centos 5.5. The application is running almost withoit problems. The only problem are the form where i put in numbers. Here is the description of the problem: When i write 1,1 and the click to the next field, the field changes to 1,10000. First thing i tried to change is to write 1.1 (note the dot instead of a comma), but the problem

Dear all, Thank you very much for the help. ylim=c(-5, 80) worked.? Regarding the reproducible example, I used dput () and saved the file as txt. It is not the first time that I used this way and normally it works. Because when I try to attach a .csv file with the data, most of the time it doesn't go through.? I will know for the next time.? Many thanks. Regards,Maria ???? 2:11 ?.?.

Dear Maria The file you attached to your first e-mail did come through but I think some people on the list must have missed it.

Hello, I'd like to use the add=TRUE parameter to add a second data line (series) to an existing plot, but R is giving me an error (see below). This code: > rap<-plot(aspen_sort,ylim=c(1,10000),log="y") ...produces the plot to which I'd like to add the second line. But this code: > rap<-plot(pine_sort,add = TRUE) ...produces this error: Warning messages: 1: In

Dear list, I am currently doing some simulation studies where I want to compare different scenarios. In particular, two scenarios should be compared: 10.000 cases in 100 groups with 100 cases per group and 10.000 cases in 100 groups with random group size (ranging from 5 to 500). The first part is no problem: > id <- seq(1,10000) > group <- sort(rep(seq(1,100),100)) But I don't

Dear all I am trying to make a plot in xyplot lattice by groups. I would like to show "0" in y axis but I don't want to be aligned with the x axis. I want to be a little bit above. I have tried many options but I don't get what I want. I also tried ylim=c(0, 80) but both 0 and 80 are fully aligned with the x-axis and the upper boundary of the plot, respectively: xyplot(upper.zn +

The following is at least as much out of intellectual curiosity as for practical reasons. On reviewing some code written by novices to R, I came across: crossprod(x, y)[1,1] I thought, "That isn't a very S way of saying that, I wonder what the penalty is for using 'crossprod'." To my surprise the penalty was substantially negative. Handily the client had S-PLUS as

Hi I am currently developing a IVR application using PHP/AGI. I am using the PHPAGI class at http://phpagi.sourceforge.net/ to handle the commuication with my *. The application basically asks a caller to enter in some information which is then processed and a answer is read back out to them. I want the application to loop back to the beginning after giving the answer so they can try another

Hi OpenSSH folks, Just a quick note: this is my .bashrc: # Executed by non-login interactive shell # # scp go wild when it see this #echo "<*> Executing ~/.bashrc from '$0'. Command line: '$*'" #ps -H e #echo "<*> Finished ~/.bashrc" Line 3 was added and subsequent lines commented out. Now scp works. Looks like a little scp bug for me. CC me,
