Hello all, I have,say 4 R objects... bar1, bar2, bar3, bar4.. that I'd like to include in an R package "foobar". The desired functionality would be: > library(foobar) > data(foo) > ls() [1] "bar1" "bar2" "bar3" "bar4" I've tried the following two approaches: 1) I created the file 'datalist' under pre-build directory

This is rw2010 from CRAN. When running Rcmd check on a package I get: Warning in utils::data(list = al, envir = data_env) : data set 'vowel.test' not found Warning in utils::data(list = al, envir = data_env) : data set 'vowel.train' not found Warning in utils::data(list = al, envir = data_env) : data set 'waveform.test' not found Warning in utils::data(list

I want to generate a list (called "dataList" below) where each of its levels is named. These names are assigned to nameList, which contains all possible permutations of size two taking letters from a larger alphabet, e.g., "aa",...,"Fd",..,"Z1",... One of these permutations is the character string "NA". It seems that when I try to name one

Hello, For reasons I don't understand, data() imports CSV (Comma-Separated Values) as if they were delimited by semicolons instead of commas. (Are semicolon-separated Comma-Separated-Value files common somewhere?) Given that this is the case, if I choose to put comma-delimited CSV files in my data directory, what is the preferred method of loading these into memory?

Dear all, I have a function that for a variable number of inputs plots them to the same plot I am doing this quite simply by plot(seq(from=start, to=stop, length.out=np), datalist[[1]]$dataset                                                                  xlim=c(start, stop), ylim=c(0, 1), type="l")                                                                                      

Hello, i only got a small problem. i try to create automatic new dataframes, or png?s. the main problem i got is: how can i create automatic a new name for a file (read out by simply "for") - i tried to use "(paste...) but theres an errormessage, about a wrong declination. R told it is as.character, but need as.Real. Should i use another method than "paste"? i tried as

Dear all, I have a code that looks like the following (I am sorry that this is not a reproducible example)     indexSkipped<-NULL  ....code Skipped that might alter indexSkipped     if (length(indexSkipped)==0)         spatial_structure<-spatial_structures_from_measurements(DataList[[i]]$Lon,DataList[[i]]$Lat,meanVector)     else        

First, here's the problem I'm working on so you understand the context. I have a data frame of travel activity characteristics with 70,000+ records. These activities are identified by unique chain numbers. (Activities are part of trip chains.) There are 17,500 chains. I use the chain numbers as factors to split various data fields into lists of chain characteristics with each element of

Hello R-helpers, I have a vector x<-c(1,2,3) and a list that contains vectors datalist<-list(c(1,2,3),c(2,3,4),c(3,4,5),c(4,5,6)) and I would like to identify those list elements that are identical to x. I tried > datalist %in% x [1] FALSE FALSE FALSE FALSE but I am obviously using %in% incorrectly. I also tried messing around with lapply but I can't figure out how to specify

Dear developeRs, my package FrF2.catlg128 holds large catalogues and is supposed to gain additional ones. All the catalogues are intended for the user. So far, the catalogues were stored in the data directory, and LazyData was "no". I understand that this is not considered wise any more (if it ever was), so that I want to change to LazyData "yes" with the next release

hi all, I have a simple problem that i am not able to solve. I've a list called datalist with the following structure: [...] [[10]] [[10]]$a -1 0 1 -1 31 5 2 0 6 7 5 1 1 7 36 [[10]]$b -1 0 1 -1 31 5 2 0 6 7 5 1 1 7 36 [[10]]$c [1] 0.855 [[10]]$d [1] 0.855 [...] with [[1]] ... [[100]]. How can i get the mean value of datalist[[x]]$d, where x

The generic rule is that R is not a macro language, so looping of names of things gets awkward. It is usually easier to use compound objects like lists and iterate over them. E.g. datanames <- paste0("aa_", 2000:2007) datalist <- lapply(datanames, get) names(datalist) <- datanames col1 <- lapply(datalist, "[[", 1) colnum <- lapply(col1, as.numeric) (The 2nd

great!! thanks very much, mean(unlist(lapply(listdata, function(z) z$c))) works well. and what about getting the average table $a (displaying the average elements across all 1000 matrix)? could you please help me? I am struggling with this... thanks in advance Roberto mean(unlist(lapply(x, function(z) z$d))) should do the trick On Sun, 12 Feb 2006 20:06:12 +0000, statistical.model at

Dear All, I was trying to call a self-defined function that performs nonlinear regression and gets the corresponding prediction upper limit using nls2 package. However, weird thing happened. When I called the function in the main program, an error message "fitted(nlsmodel): object 'nlsmodel' not found" came up. But when I directly ran the codes inside the function, no error came

Dear Mailinglist, I just set up an R 2.9.1 environment with Rcmdr 1.4-6 on Ubuntu Jaunty 9.04. As I'm from Germany my $LANG variable is set to "de_DE.UTF-8". Now, when I open up Rcmdr and try to edit a new datamatrix there is no edit window appearing: Datenmatrix <- edit(as.data.frame(NULL)) ERROR: invalid device In addition, there are plenty of warning messages in the

Hi! Thanks for the replies! I understand people more accustomed to R doesn't like looping much, and that thinking about loops is something I do since I worked with Stata a lot. The syntax from Peter Dalgaard was really clever, and I learned a lot from it, even though it didn't solve my problem (I guess it wasn't very well explained). My problem was basically that I have a data matrix

Um, if you insist on doing it that way, at least use assign(varname, as.vector(get(varname))) -pd > On 4 Dec 2017, at 22:46 , Love Bohman <love.bohman at sociology.su.se> wrote: > > Hi! > Thanks for the replies! > I understand people more accustomed to R doesn't like looping much, and that thinking about loops is something I do since I worked with Stata a lot.

I can't run fix() or edit() anymore. Did I break my system? I'm running Debian Linux with R-2.14.1. As far as I can tell, the R packages came from Debian's testing "wheezy" repository. I would like to know if users on other types of systems see the same problem. If no, then, obviously, it is a Debian-only issue and I can approach it from that point of view. And if no other
