I'm confused, hope someone can point out what is not obvious to me. I thought I was creating a new data frame by 'deleting' rows from an existing dataframe - I've tried 2 methods. But this new data frame seems to remember values from its parent - even though there are no occurences. Where does it get the values versicolor and virginica from and give then a count of 0? What

Hi, I am a newbie to R and this may be too simple to ask. I am trying to find out a string function in R that returns the index of a character. For e.g. indexOf("Test1234", '4') would return 8. Is there a similar function in R. I tried searching the documentation and could find other useful string functions, but not the index function. Thanks in advance. Regards, Harsh

Hola a tod@s, ¿alguien me podría clarificar la diferencia entre "\." y "\\." en el siguiente caso? (He mirado ?regex, ?cat, ?Quotes y FAQ 7.37 y no lo acabo de ver) > a<-"hola.me.llamo.pepe" > a [1] "hola.me.llamo.pepe" > strsplit(a,"\.") [[1]] [1] "" "" "" "" "" ""

Hi Duncan, when I run "opt -std-compile-opts" on the original source code it has the same output of O3. when I run "opt -std-compile-opts" on the -O3 optimized code, things get even more weird, it outputs the following code: while.body: ; preds = %while.body, %entry %indvar = phi i32 [ 0, %entry ], [ %indvar.next.3, %while.body ] %tmp

I require some help in debugging this code  library(neuralnet) ir<-read.table(file="iris_data.txt",header=TRUE,row.names=NULL) ir1 <- data.frame(ir[1:100,2:6]) ir2 <- data.frame(ifelse(ir1$Species=="setosa",1,ifelse(ir1$Species=="versicolor",0,""))) colnames(ir2)<-("Output") ir3 <- data.frame(rbind(ir1[1:4],ir2))

Hello, I'm trying to fill CID data into the astdb using AsteriskWin32's asterisk.exe, to no avail: The batch file stops after the first line, and just waits: ---------------------------------------- rem c:\cygroot\mystuff>import.bat rem rem c:\cygroot\mystuff>C:\cygroot\bin\asterisk.exe -rx 'database put cidname 123 "My cellphone"' rem rem Asterisk module

Dear R users, I'd like to make this data rem.y = c(-1,0,2,4,5) from y = c(-1,-1,0,2,2,2,2,4,4,5,5,5,5,5). That is, I need to remove repeated values. Here is my code, but I don't think it is efficient. How could I improve this? #------------------------------------------------------------------------ y = c(-1,-1,0,2,2,2,2,4,4,5,5,5,5,5) n=length(y) for (i in 1:n) #

Hi, i'm having a serious problem with the following logon-script. It works under W2k, but not under W98, although W98 tells it is running startup-script .. First my smb.conf (only interesting parts) : ---snipp--- [global] server string = Samba-PDC %v on %h workgroup = WORKGROUP encrypt passwords = yes netbios name = 486dx66 domain master = Yes

Hi folks, I couldn't find a specific XOR (OR and AND) optimization on llvm, and therefore I am about to implement it. But first I would like to check with you guys that it really does not exist. For a simple loop like this: nbits = 128; bit_addr = 0; while(nbits--) { bindex=bit_addr>>5; /* Index is number /32 */ bitnumb=bit_addr % 32; /* Bit number in longword */

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at

SPSS seems to have changed its default datafile format, resulting in issues for read.spss(). In Windows this results in a warning, in Debian the import completely fails: Debian (R version 2.8.0 (2008-10-20) i486-pc-linux-gnu, foreign_0.8-29) > read.spss("/home/jeroen/samples/Tomato.sav") Error in iconv(names(rval), cp, "") : unsupported conversion from 'CP65001'

Dear R-Help, I am using the 'mfp' package. It produces three plots (as I am using the Cox model) simultaneously which can be viewed together using the following code: fit <- mfp(Surv(rem.Remtime,rem.Rcens)~fp(age)+strata(rpa),family=cox,data=nearma,select=0.05,verbose=TRUE) par(mfrow=c(2,2)) plot(fit) They can be viewed separately but the return key must be pressed after each graph

Hello All, I am trying to carry out variable reduction. I do not have information about the dependent variable, and have only the X variables as it were. In selecting variables I wish to keep, I have considered the following criteria. 1) Percentage of missing value in each column/variable 2) Variance of each variable, with a cut-off value. I recently came across Weka and found that there is an

Hi R users, I request members of the R community to consider filling a short survey regarding the use of R. The survey can be found at http://goo.gl/jw1ig Please accept my apologies for posting here for a non-technical reason. The data collected will be suitably analyzed and I'll post a link to the results in the coming weeks. Thank you all for your interest and for sharing your R usage

I have a data file from which I need to read portions of data but data location/quantity can change from file to file. I wrote some code and have a working solution but it seems wasteful to have to do it this way. Here's the contrived incomplete code. datalines <- readLines(datafile.pathname) # marker will appear on line preceding and following # actual data offset.data

Hi, I'm having a MAJOR issue with an rsync backup script that is actually OVERWRITING the files that it should be backing up! The thing is, the same script (with different source/destination variables) runs FLAWLESSLY on another file server! Background: 2 OS X client computers running 10.4.11 (1 intel, 1 PPC). both are running rsync v2.6.3. rsync is backing up from one firewire HD(afp

This is a really good point, and definitely a recurring theme on this mailing list. :) I wonder, what are some better options for handling this issue, other than to keep saying "just use 8/16/32kHz"? - Extend Speex to support other sample rates (seems unlikely..?) - Integrate a resampling algorithm into libspeex - Maintain a list of recommended resampling libraries that work well

I see that this was the right place to fire off this question. Thanks for your feedback. It has given me a base to start some trials. I used to use EAC on Windows, but I tend to only use open source software as much as possible and I don't use Windows any more. I gave a brief look at abcde, but it is clear I need to look at this some more. It looks like it has the potential to do everything I
