Hello all I am new in R and so easy stuff are difficult... let say that I have a list test <- list(a=c("x","v"),b=c("n","m")) how can I without a loop get test$a bind with test$b (obviously in real life their would be many fields) Cheers and thanks -- View this message in context: http://n4.nabble.com/Bind-field-of-a-list-tp1561676p1561676.html Sent

Dear R users, Let's say I have a list with components being 'm' matrices (as exemplified in the "mylist" object below). Now, I'd like to subset this list based on an index vector, which will partition each matrix 'm' in 2 sub-matrices. My questions are: 1. Is there an elegant way to have the results shown in mylist2 for an arbitrary number of matrices in mylist?

|Hello, Given a function with several arguments, I would like to perform an lapply (or equivalent) while holding one or more arguments fixed to some common value, and I would like to do it in as elegant a fashion as possible, without resorting to wrapping a separate wrapper for the function if possible. Moreover I would also like it to work in cases where one or more arguments to the original

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

All, I'm seeing duplication of DICompileUnits in a pass that worked in 3.8. I assume I'm doing something wrong. Would someone be willing to point me in the right direction? The below minimized pass reproduces my issue in 4.0 with the following error: DICompileUnit not listed in llvm.dbg.cu !1707 = distinct !DICompileUnit(language: DW_LANG_C_plus_plus, file: !1, producer: "clang

Dear All   I have the following code set up: Code #1 a <-matrix(seq(0,8, by = sign(8-0)*0.25)) b <-matrix(seq(8,16, by = sign(16-8)*0.25)) c <-runif(1000,50,60) d <-exp(-c*a)+exp(-c*b)   This will give me the obvious error message of lengths not matching. What I am trying to do here is to have 33 rows x 1000 columns d values calculated in total. As an eaxmple for visual, this is what

Thank you. What I need to do to address this? Open an issue on bugs.llvm.org? I'm not sure what the fix needs to be in the cloner.

Hi list, This looks similar to the problem reported here https://stat.ethz.ch/pipermail/r-devel/2006-April/037199.html by Henrik Bengtsson a long time ago. It is very sporadic and non-reproducible. Henrik, do you remember if your code was using reg.finalizer()? I tend to suspect it but I'm not sure. I've been hunting this bug for months but today, and we the help of other Bioconductor

Greetings, I need to compare the ratios of vector sizes like this: length(object1) / length(object2) I have many vector objects to compare, so I would like to do it in a loop. I created a loop like this: mat1 <- matrix() for (i in 1:6) { for (j in 1:6) { mat1[i,j] <- length( paste("object",i,sep="")) /

Hello I want to unlist the attached element getting only the first element in each element of the list. The last element of the list looks as this: [[5065]] [[5065]]$Pluv3Meses [1] 274.4 [[5065]]$PluvMesesMedio [1] 378.2667 [[5065]]$Pluv2UltimosMeses [1] 23.33333 So I would like to get for each element of the list the element called Pluv3Meses. The whole list has 5065 elements but when I try to

Hi everyone, My apologies if this isn?t the right place to submit this?I?m new to the R-devel community and still figuring out what is where. If people want to skip my writeup and just look at the code, I?ve made a repository for it here: https://github.com/ahl27/new_dendrapply/tree/master. I?m not quite sure how to integrate it into a fork of R-devel; the package structure is different from

Hello, I have a data.frame and I want to transfor it in a list of rows or columns. I can do apply(myDataFrame,MARGIN=1,FUN=???) I remember that there is a function which mean return or access column ... something like "::" or "]," or "[," I can't remember can somebody refresh my memory? -- View this message in context:

Greetings, Say I have defined mp <- function(a) function(x) x^a f2 <- mp(2) and I would like to retrieve the "a" which is local to f2. Two options come to mind; get("a", envir=environment(f2)) eval(substitute(a), environment(f2)) I'm curious if one of these is preferred over the other in terms of efficiency, robustness, aesthetics, etc. Or perhaps

Hello, I would like to be able to plot an array on a plot, something like: |arg1 | arg2 | arg3 val1| 0.9 | 1.1 | 2.4 val2| 0.33 | 0.23 | -1.4 val3| hello| stop | test I know Rwave is good to report but don't want to use it. ?

Hello All, I have multiple "list of lists" in the form of Mylist1[[N]][[K]]$Name_i, with N=1..6, K=1..3, and i=1..7. Each Name_i is a matrix. I have 30 of these objects Mylist1, Mylist2, ... I would like to merge these lists by each Name_i using rbind, but I couldn't figure out how to do it. What I want at the end is a single "list of lists", again in the form of

Hello all, I looking at package dse or vars or mAr I know how to simulate a VAR(p) process, my problem is that most of those processes are unstable (not weakly stationary). Do anybody know how to generate a random VAR (or VARMA even better) process that is weakly stationary?

Hello all, my question for today is the following : I have 1. a date (in a string but straightforward to convert to any format) 2. the time as the number of milliseconds elapsed since hour 00:00:00.000 of this date. My question is : 1. Is there a in built function that can give me the date+time (as POSIX object for instance) from what I have ? -- View this message in context:

Dear R Users, A bit of an elementary question, but somehow, I haven't been able to figure it out. I'd like to changes the column names of a data frame, so I am looking for something like col.names (as in row.names). Could someone please show me how to change the column names of a data frame ?

Hi All, Im interested in creating a function that will convert a variable within a data.frame to a factor while retaining the original name (yes, I know that I can just: var <-factor(var) but I need it as a function for other purposes). e.g.: # this was an attempt but fails. facts <- function(meta, mod, modname = "spec") { meta$mod <- factor(meta$mod)
