Dear R helpers Suppose I have a vector as vect1 = as.character(c("ABC", "XYZ", "LMN", "DEF")) > vect1 [1] "ABC" "XYZ" "LMN" "DEF" I want to reverse the order of this vector as vect2 = c("DEF", "LMN", "XYZ", "ABC") Kindly guide Regards Vincy [[alternative HTML

Hi, I wonder if anyone knows how to generate a list of objects, e.g. ten vectors with names: vect1, vect2, ... , vect10. My own idea was to use something like: for (i in 1:10) print(paste("vect", i,"<-NULL",sep="")) but the result is: "vect1<-NULL" ... "vect10<-NULL" and not vect1<-NULL ... vect10<-NULL as I would

Hi R developers and debian users: Finally I found how to work with aggregate() function on the last patched version fo R. I you use this command it fails: aggregate(state.x77, list(Region = state.region), mean) But if you modify it in this way, it works!: aggregate(state.x77, list(Region = state.region), function(x) mean(x) ) Is it necesary to change the example? What is changing in

Hi everybody, I am currently working on mixtures of two densities ( f(xi,teta)= (1-teta)*f1(xi) + teta*f2(xi) ), particularly on the behavior of the variance for teta=0 (so sample only comes from the first distribution). To determine the maximum likelihood estimator I use the Newton-Rapdon Iteration. But when computing the first derivative I get a none linear function (with several asymptotes)

Hello, i would like to ask you another question. Is exist anymethod to vectors that tells me the last element?That is to say,I have a vector, I want to return the position of last element. I hope having explained. A greeting, Ignacio. -- View this message in context: http://old.nabble.com/Method-tp26493442p26493442.html Sent from the R help mailing list archive at Nabble.com.

Hi R developers: Congratulations for the new R 2.10.0 version. It is a huge effort! Thank you for your work and dedication. I just want to ask how to make this "strip blank" function to work again (it works on R.2.9.2). alumnos$AL_NUME_ID<-sub("(^ +)|( +$)","",alumnos$AL_NUME_ID),) "alumnos" is a data base with 900.000 rows and 72 columns. and

I have a set of character vectors of uneven length that I have stored in a list. I can easily enough get any column of them using lapply but what I want is to be able to create a matrix of them. Other than some kind of brute force looping approach I have drawn a blank. Would somebody please suggest something? Thanks Example. mylist <- list(aa=c("cat","peach" ),

HI, R user, I generate the vectors with the same length. I want to put each vector into each column of data frame. Why it doesnt work`? rm<-data.frame() for(a in 1:6){ rm[,a]<-getmeasure(p1,a,speech) } thanks a lot Tammy _________________________________________________________________ Share your memories online with anyone you want.

Hi R users: I don't know if you have had the following problem trying to export to an "xls" format file in a non windows platform. I try to use the following packages: 1. dataframes2xls (version 0.4.4) (with phyton 2.7 and 3.1) 2. WriteXLS (version 1.9.0) (with perl and testPerl working) Even "xlsx" package that take too long and do not finish. The data frame I try to

Peter, One other thing. The first two times it crashed I erased the file tree created by rsync so that the snaphot started from scratch again. Each of these two times it got to exactly the same file: usr/lib/locale/es_CO/LC_COLLATE when it crashed. That was when I stopped rebuidling and re-cabling my hardware, because I saw a determinate pattern in the crashes... (sheepish) should have said

Dear R Users, I have developed the following code for importing a series of zipped CSV by parallel computing. My problems are that: A) Some ZIP Files (Which contain CSVs inside) are corrupted, and cannot be opened. B) After executing parRapply I can only see the last.warning variable error, for knowing which CSV have failed in each node, but I cannot see all warnings, only 1 at a time. So: *
