Dear R-List, I am very new to R and programming itself, so my question may be easy to answer for you. I tried a lot and read through the manuals, but I still have the following problem: I have 2 data-frames: Number<-as.numeric (Number) Name<-as.character (Name) TAB1<-data.frame (Name,Number) - it looks like this:- Name Number A 2 A 3 A 6 B 8 B 12 B 7 C 8 D 90 E 12 E 45 佲仸

Hi Given that things like the following work > a <- c("-.1"," 2.7 ","B") > a [1] "-.1" " 2.7 " "B" > as.numeric(a) [1] -0.1 2.7 NA Warning message: NAs introduced by coercion > I naively expected that the following would behave differently. > b <- c('10%', '-20%', '30.0%',

Hi I've been greatly enjoying the functionality the zoo package offers. However I've hit a snag with the following code > a <- zoo(matrix(1:10,5,2), 2001:2005) > a 2001 1 6 2002 2 7 2003 3 8 2004 4 9 2005 5 10 > a[I(2003), 2] 2003 8 > a[I(2003), 2] <- NA Error: subscript out of bounds > I've also tried > coredata(a[I(2003), 2])

I have a big contingency table, approximately of size 60*2*500*500, and I need to count the number of cells containing a count of 1 for each of the factors values defining the first dimension. Here is my attempt: tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM)) tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0)) tab3<-apply(tab2,1,sum) Computing tab2 is very slow. Is there a faster

Dear R-users, I am very new to R, so maybe my question is very easy to answer. I have the following table: TAB1<-data.frame(Name,Number), "Name" and "Number" are all character strings, it looks like this: Name Number ab 2 ab 2 NA 15 NA 15 NA 15 cd 3 ef 1 NA 15 NA 15 gh 15 gh 15 I want to delete all the rows

Hi all, how can I divide two tables of the same dimension so that all names are preserved, ie do not become NA? I have "tab1" and "tab2", each having names in the first column. I want "tab3" with the same names and values "tab1/tab2". Thanks, Serguei

Dear R List, I am a new to R, so my question may be easy to answer for you: I have a dataframe, for example: df<-data.frame(loc=c("A","B","A","A","A"), year=as.numeric(c("1970","1970","1970","1976","1980"))) and I want to create the following table without using loops: 1970-74 ;

Dear R- list, I have some data to present with histograms. Therefore I used hist(...). I have few values with almost 80% of the frequencies (totaly 800) and some other values with low frequencies ( totaly 5 -10 ) that I want to emphasize. Therefore I want to "cut" the y-axis on 100, but I don't know how to deal with this. Thanks in advance, Michael Graber

Dear R list, I am a newbie to R and programming itself, so my question may be easy to answer for you. I wanted to create a scatterplot and i used the following code: par(mar=c(10, 4.1,4.1,2.1)) plot(q$location,q$points, , las=2, cex.axis=0.5,xlab="", ylab="" ) #location are character strings, there are about 70 locations #points are numeric, there are more than 4 points for

Dear Sir, I got a problem with my program. I would like to classify my data using bagging support vector machine ensemble. I split my data into training data and test data. For a given data sets TR(X), K replicated training data sets are first randomly generated by bootstrapping technique with replacement. Next, Support Vector Mechine (SVM) is applied for each bootstrap data sets. Finally, the

Hi all, I have a problem to read csv file with comma as decimal. The numbers were readed as strings. I used the following string in R, but I do not understand why it does not work. tab <- read.csv2("Specimen_RawData_1.csv", header = TRUE, sep = ";", dec = ",", nrows = -1) In addition, I copy/past into the post the link to the csv file generated by my instrument.

Dear R-WinEdit users, I got a simple question, but somehow I cannot find the answer, although I have tried a lot! I got an ASCII-file and I want to import it into R, so that every character is defined by [i;j]. The rows are not of the same length. the file looks like the following shortened abstract example: name: xxxxx xxxx age: 9.9.99 record number: 999 title: xxxxx xxxx xxx keywords: xxx xx

Hi. I have 2 tables, with same dimensions (8000 x 5). Something like: tab1: V1 V2 V3 V4 V5 14.23 1.71 2.43 15.6 127 13.20 1.78 2.14 11.2 100 13.16 2.36 2.67 18.6 101 14.37 1.95 2.50 16.8 113 13.24 2.59 2.87 21.0 118 tab2: V1 V2 V3 V4 V5 1.23 1.1 2.3 1.6 17 1.20 1.8 2.4 1.2 10 1.16 2.6 2.7 1.6 11 1.37 1.5 2.0 1.8 13 1.24 2.9 2.7 2.0 18 I need generate a table of averages, the

Dear all, I'm starting to learn R, but I'm already programing for a while, using ViM as editor. Therefore I'd like to be able to use R together with ViM. My question now is, whether there are already people out there knowing how to do this in a similar easy way as with Emacs, and if those would be willing to share this knowledge. I did already research on the web on this topic,

Hi all I was wondering whether there has ever been an update on the rownames and colnames behaviour as described by Eric below? I still get the same behaviour, exactly as described by Eric, on my WinXP installation of R-2.3.0. I also posted a message to r-help on Friday but looking through the online archives it seems to have not made it to the list. I would agree with Eric that a consistent

Hi, I would like to open several tables with a loop, using something like : ----------------- $ ls 1.txt 2.txt 3.txt 4.txt $ R > for (i in 1:4) tabi<-read.table("i.txt") Error in file(file, "r") : unable to open connection In addition: Warning message: cannot open file `i.txt' ------------------ thanks for any help Tristan Lefebure

I compiled OpenSSH 3.6.1p1 on NCR MP-RAS v4.3 (or at least "uname -a"'s output of 4.0.3.0 suggests v4.3, I'm not positive). I was able to compile zlib (1.1.4) and openssl (0.9.7a) with little trouble. OpenSSH took hand-hacking the includes.h file as follows: diff -cr openssh-3.6.1p1/includes.h openssh-3.6.1p1-customized/includes.h *** openssh-3.6.1p1/includes.h Sun Oct 20

Hi List, I've checked RHEL6 beta2, it's libvirt 0.8.1, but I need 0.8.3 to support vSphere 4.1, I know I can compile it by myself, but our Red Hat's customer wanna have "half official" rpm package for their test, anyone would help me to make rpm for RHEL5.5? And, do we have any roadmap about libvirt 0.8.3 to be official rpm package in RHEL6? Regards, Joel -- ???
