Dear r-users! I would like to cross two data frame which have the same row number but different in the number of column. Can anybody help me for this case ?

Dear all, I would like to multiply two matrixes with the different dimension column by column. Let make an example: If I have two matrixes "X" and "Y"as follow: X<- matrix(1:12, nrow=4, ncol=3, dimnames=list(c("A","B","C","D"), c("stage1","stage2","stage3"))) Y<- matrix(1:28, nrow=4, ncol=7,

I have the following problem: I measured co2 on 6 paired sites (one grubbed and one non-grubbed fence per site -> grubbing = treatment). These measurements I repeated 15 times over 2 years. So, now my problem is how to analyze these data. I tried the following model: mod1_CO2<-lme(co2~treatment+time,random=~1|site,data=CO2_t1_t15) I think with the random effect I included the paired

Dear R colleagues, I am trying to create a new column in a data frame, which converts values and NA's from another column into binary format. Essentially I need the NA's to become 1 and the rest to be 0. The code I wrote is returning the following error message: Error in if (mort[i, 4] != NA) mort[i, 8] <- 0 else if (mort[i, 4] == : missing value where TRUE/FALSE needed

Hi, Sorry to bother, but I checked around and did not succed creating a bundle from six existing packages (which are checkable, installable, etc. individually). I carefully followed the procedure given in ch. 1.1.5 Package bundles. However, I am getting hoffmann at fluke:~/R/Sources >R CMD check cwhmisc * checking for working latex ... OK * using log directory

Dear R Helpers, I want to localize my plots, i.e. the numbers by x & y axis be Persian, using Persian numerals and Persian decimal separator. I change the locale to fa_IR.utf8, but nothing on plots change. I can change the numerals shaping to Persian ones (???? instead of 1234) using some non-standard fonts but the decimal point is a problem. I asked about that in Persian-Computing mailing

I have a strange problem that I have been experienceing with dovecot: Dovecot version : 0.99.10.4-1 Using IMAP: When I restart the OS (windows XP) and open up Outlook 2002 SP2 I don't automatically get my IMAP folders on the DOVECOT imap server.

Hi, I just downloaded and installed samba2.2.8.a on a sun4u sparc box running Solaris8. The installation process completed w/o errors and I can now confirm that by "$pkginfo -l samba". I can even start and stop samba by "/etc/rc3.d/S99samba.server start" and see that smbd and nmbd processes are running. However, I can not find the "configure" file in the source

Hi all, I tried to add a new user to a Samba share, I did all the usual: made a Unix account on the Unix server for the user which was the same as the user's window's UID. Put her name as a valid user for that directory in server:/etc/opt/samba/smb.conf, and stopped and started server:/sbin/init.d/samba server; nothing worked. Interesting observations: 1- After performing the steps

Hi there, (sorry Martin, ich habe den falschen Empfaenger erwischt :-( ) Is there a function in the base package or elsewhere which returns TRUE and not NA, even if NA is involved: (I did not find in the help system :-( ) if ( x==something & !is.na(something)) or if ( x==something & !is.na(x==something)) If "something" is complicated, a function would be handy. Thanks

Hi all, I just cannot think of how to do it: I want to take the first variable (column) of a data frame and regress it against all other variables. bla <- function (dat) { reg <- lm(whateverthefirstofthevariablenamesis ~., data=dat) return(reg) } What kind of function do I have to take instead of the whateverthefirstofthevariablenamesis, eval(), substitute(), get(), ... to

Hi there, I am interested in the inner workings of wilcox.test: > wilcox.test function (x, ...) UseMethod("wilcox.test") <environment: namespace:stats> how can I get at the code, if it is R-code? For Methods one should be able to learn what extension to use, but here default or such do not help. Is there a wayplot.default to learn which different versions of

Dear R-helpers, I want to see the code used when printing (using print(object) or by just typing the object name) for a class from a package. I can see the summary code using packagename::summary.classname but nothing for print method and also plot methods. In general, how can I see the COMPLETE code for a package? not just the function defs? -- Majid Einian, PhD Candidate in

Hi, I am trying to create the assignment function: "substring<-" <- function(text, first, last=100000, sub) { if(is.character(first)) { if(!missing(last)) stop('wrong # arguments') return(sedit(text, first, sub)) } lf <- length(first) if(length(text)==1 && lf > 1) { if(missing(last)) last <- nchar(text) last <- rep(last,

Hi, Using help under help.start() is working fine (html) Q1: using > ?solve results in the message "sh: ~/R/tmp/R4f32S1cfb: cannot open" displayed in the XEmacs buffer "help[R](solve)". BUT there exists a file R.R4f32S167e in that directory. (not quite the same name). Does the "sh: " prefix suggest that the shell "sh" is run, although my
