Hello, I am trying to test a function argument to see if it is or is not a useful number. However I cannot seem to find a test that works. For example > f = function(x) { + print(exists("x")) + print(is.null(x)) + } >rm(x) > f(z) [1] TRUE Error in print(is.null(x)) : Object "z" not found exists gives TRUE, but then any other kind of test I try to run gives me an

Hello, What options are available for me to debug my R scripts? For example I normally do something like >source("myfunctions.R") >function1("height", "weight") myfunctions.R is a large R source file that contains many functions. function1 is the "main" function in myfunctions.R. It calls many other user-written functions that are also in

Hi, I have an intermittent pxelinux boot problem. It happens rarely, for example it happened one day and then did not happen again until 6 days later. However when it does happen it is rather serious as it affects all clients on the network. Here is some basic info: - IBM netvista PCs, built-in pxe, banner says it is "PXE 2.x". - happens rarely, but when it does it affects all clients.

When I use R, I am accustomed to developing programs in a text processor, and then copying from the text processor and pasting into R. This usually works fine, except that using the default text processor in Suse 9.0, long programs don't transfer completely. Using the 'source' program, also only works with small programs. Suggestions?

An NA in the rownames of a matrix (or dataframe) causes misalignment when the matrix is printed: R> x <- matrix(1:12, 3,4, dimnames=list(letters[1:3], LETTERS[1:4])) R> rownames(x)[2] <- NA R> x A B C D a 1 4 7 10 <NA> 2 5 8 11 c 3 6 9 12 The bug is in function Rstrlen, in src/main/printutils.c. MatrixRowLabel and MatrixColumnLabel (same file) rely on Rstrlen

Full_Name: David D Degras Version: 2.8.0 OS: Mac OS X Submission from: (NULL) (128.135.239.11) I have recently installed the version 2.8.0 of R along with package fda (v 2.0.2) and its dependencies (including package splines v. 2.8.0). Here are my problems: 1) The package splines should feature functions such a predict.bs, predict.bSpline and such and it does not! I can make calls to bs, ns,

Arnaud, Short answer may be that the tibble data structure will not be supporting row names and you may want to simply save those names in an additional column or externally. My first thought was to simply save the names you need and then put them back on the tibble. In your code, something like this: save.names <- names(my.ret.lst) result.tib <- as_tibble_col(unlist(my.ret.lst),

I work with a list of crypto assets daily closing prices in a xts class. Here is a limited example: asset.xts.lst <- list(BTCUSDT = structure(c(26759.63, 26862, 26852.48, 27154.15, 27973.45), dim = c(5L, 1L), index = structure(c(1697068800, 1697155200, 1697241600, 1697328000, 1697414400), tzone = "UTC", tclass = "Date"), class = c("xts", "zoo")), ETHUSDT

Hi everyone, I am trying to conduct a synthetic control analysis using the MSCMT package. However, when trying to run it I get a very cryptic error message saying "Error in lst[[nam]][intersect(tim, rownames(lst[[nam]])), cols, drop = FALSE]: subscript out of bounds". Does anyone know what this means and why I receive this error? I attached the code & dataset used in the

Hi Tim, How do you make a logo show during boot? Thanks,

Dear all, A few months ago, I asked for your help on the following problem: I have a list with three (named) numeric vectors: > lst = list(a=c(A=1,B=8) , b=c(A=2,B=3,C=0), c=c(B=2,D=0) ) > lst $a A B 1 8 $b A B C 2 3 0 $c B D 2 0 Now, I'd love to use this list to create the following data frame: > dtf = data.frame(a=c(A=1,B=8,C=NA,D=NA), +

Is it possible to avoid the loop in the following function (or make the function otherwise more efficient) and can someone point me to a possible solution? (It would be great if hours could be reduced to seconds :-). # --------------------------------------------- RanEigen=function(items=x,cases=y,sample=z) { X=matrix(rnorm(cases*items),nrow=cases,byrow=F) S=crossprod(X-rep(1,cases) %*%

*I've been trying for several weeks to install R-2.2.1 on a PC with an AMD Athlon 64 2800*+* processor running Mandriva 2006_64. After unpacking R-2.2.1.tar.gz I ran ./configure.

Hello, I am using R 2.2.1 with sn 0.4.0 and am trying to save a dns2.plot as a jpg file.

Dear Community, I'm interested in developing a package that could ease the command-line learning curve for new users. It would provide more detailed syntax checking and commentary as feedback. It would try to anticipate common new-user errors, and provide feedback to help correct them. As a trivial example, instead of > mean(c(1,2,NA)) [1] NA we might have > mean(c(1,2,NA)) [1]

Hi all I'm trying to install R 2.3.0 under Suse 10.0. As I'm using SSH to login into the SUSE server, I can't use YAST2, so I have to use rpm -i in the shell. The system tells me that I need some other packages such as xorg-x11-fonts-100dpi, blas, libgfortran.so.0(). Is there some website where I can download and install these packages? Thanks a lot!

Dear list, I hope this is the right place to post a feature request. If there's exists a more formal channel (e.g. as for bug reports), I'd appreciate a pointer. I work a lot with named nested lists with arbitrary degrees of "nestedness". In order to retrieve the names and/or values of "bottom layer/bottom tier", I love the functionality of 'unlist()', or

Hello :-) I am trying to run the next script, it generates "random areas" inside a map of the american continent, and then plot it, it?s suppose that every frame gives you the evolution of the program but at some point it stops with the weirdest of the errors I?ve ever seen in R, I don?t even have a line like that :-| Error in if (random_matrix[x_list[random_sq] - 1,
