Hello everyone, I want to split a data.frame by the column date . The data frame looks like this date time open close 02.01.2011 09:00:00 1000 1200 02.01.2011 09:05:02 1200 1203 ... 01.02.2011 10:01:21 1029 1110 ..... 30.03.2011 12:02:12 1231 1200

I encounter a strange problem with scp / sftp: I travel quite a bit. Normally I never have had any problems using ssh / scp / sftp to connect from my laptop to my computer at home / in the office. Currently (for the next 6 months, too long to ignore it) I'll stay in a place where scp / sftp seem to fail, while as usual I have no problems to establish an interactive ssh connection to these

Dear R-User, I'm trying to visualize the results of the power calculation with the function power.t.test(). Therefore I want to plot the related t-distributions and shade the surfaces indicatingt the type I error, the type II error and the power. For sample sizes greater 30 I got results which are very satisfying. For small sample sizes I got stuck and did'nt find a mistake. To show you

Hi List, my problem is the following: I use Samba 3.5 with AD password authentification and uid/gid information in local files. Everything seems to work so far, when i create files via samba the created files have correct user/group information on linux filesystem level (so i think id mapping works basicly). The only thing that does not work is deleting files which - belong to other users from

Dear all, I'm trying to rearrange variables in a table in a custum order for using it with levelplot. So far I could only find examples showing how to sort alphabetically. Here is a short example:? a <- c("Anna","Anna","Michael","Klaus","Klaus","Anna","Fritz")? b <-

Dear R-helpers ? I have 7 data points that I want to fit a continuous curve to, that should look similar to a sine wave My data points would mark the local minima and maxima respectively. This is what I?ve got so far. And I would keep doing so, but sadly nls() then says that it has reached the maximum number of Iterations? ?

Hi there, I try to boot tiny core linux with PXE boot (pxelinux.0) over ethernet. But during the boot I get 2 times a - Invalid or corrupt kernel image - message. The third time the bzImage boots fine. Could someone help me? /agni ____________________________________________________________________ Psssst! Schon vom neuen WEB.DE MultiMessenger geh?rt?

Hi @all! Sorry about that many questions, but after searching and reading tons different web sites, I didn't find exactly what I am searching for. So, I know that with the -z Option rsync compresses the files with gzip, than the files are transfared and at the target machine uncompressed. I want to know, is there a possibility to see how big the compressed file is, which rsync generates

Hi @all! I tested what happens with a file which is saved at a FAT32 partition and then this partition is converted to NTFS. So first I transfered the file with rsync from the FAT32 partition to my Linux /home folder. Then I converted the FAT32 partition to NTFS. After the convertation I transfered the file again to see what has changed (amount of data). I was surprised!!!! Nothing has changed!!!

Sehr geehrte Damen und Herren, An der Fachhochschule Winterthur wurde f??r mich im Rahmen einer Diplomarbeit (Prof. Ruckstuhl) ein R-Programm zur Auswertung von IR-Spektren (line-shape-Analyse zur quantitativen Analyse von Gasmischungen) entwickelt. Die Daten werden einer Excel-Tabelle entnommen. Bisher werden die spektroskopischen Daten ??ber den Inhalt von 64 Kan??len ??ber die

Hello, I am looking into description of surf.ls(spatial) and see under value $beta - the coefficients. When I use polynomial of degree 2 to fit surface I expect to get 4 coefficients: z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4 What do beta really stand for and why do I get $beta vector of length 6? Thakns, Mark

Dear list, im facing an issue of statistical data analysis that I consider myself unable to resolve in R so i hope to get some valuable insights from you. i run an ANOVA with four factors; factor4 is an between factor (two different groups measured), the others are withins (tested across /all/ subjects). accordingly, my model looks as follows: fm1

I'd like to give the dbox format a try, but I could not find any information on how to enable it. There's information on how to set mail_location for the Maildir and mbox formats in the wiki and also in the commented configuration file, but how to set it for dbox is strangely missing. I took a guess with 'mail_location = dbox:~/dbox', but that didn't work, so it's probably

Dear List, I would be pleased if someone can help me with the following issue: I'm about to plot two time series in one plot via ts.plot which looks like: ts.plot(series1, series2, main=main, xlab=xlab, ylab=ylab, col=c("green", "red", "blue"), lwd=2) The problem is, that R automatically sets the x axes labels in 5-year-intervalls. Every

Hi all! I've got a question about rsync using the MD5 algorithm. I know that rsync makes blocks of a file and then compares the checksums of each block. If the checksum is unequal the block is tranfered. Otherwise it could be that the checksum is the same but the block is different. Therefor rsync uses a 128 BIT MD5 algorithm. Now, at what filesize is it better to check the whole file

Hi @all! I want to backup Windows files to a Linux Server including the Windows ACLs.

Hi, I ran a negative binomial regression (NBR) using the Zelig-package and the negbin model. When I then try to use the simumlation approach using the setx () and sim() functions to calculate expected values and first difference for different levels of one of my independent variables, I get 50 errors warnings, telling me that the calculation rpois produced NAs. However, the data I use

hello, ladyes and gentlemans. check this: means<-c(4,6,8) stand.error<-c(0.1,0.3,0.5) now i've strongly tryed to scatterplot the means(y-axis),by showing their sd with the arrow(..,code=3,angle=90) function. The problem is that my x-axis has categorical values (say, factor(x)), and the arrows() can't recognize them as right coordinates. ????? thank you all in advance B.F. insubria
