Hi, How to rbind these vectors from a list?: > l <- list(a = c(1, 2), b = c(1, 2, 3)) > l $a [1] 1 2 $b [1] 1 2 3 > do.call(rbind, l) [,1] [,2] [,3] a 1 2 1 b 1 2 3 Warning message: In function (..., deparse.level = 1) : number of columns of result is not a multiple of vector length (arg 1) > -J

Dear R users, I have huge dataset like the bellow (prepared in notepad in txt format: 31;39;00N+65;40;00E T 36;31;42N+69;04;21E T 34;10;00N+69;41;00E T 34;34;00N+69;06;00E T 31;40;00N+65;44;00E T 35;00;00N+69;07;00E T 34;00;00N+69;53;00E T These are geographical coordinates, degree minute, seconds.   latitude      longitude 31;39;00N+65;40;00E T I would like to plot them on the map. I would

Hello, I have a series of coordinates (latitudes and longitudes) each one/several associated to a code (from 1 to 28). I used function points (latitude, longitudes) to transfer them to a per-prepared map. 1- I wonder how I might be able to automatically add codes (1-28) to the map too? 2-Moreover, mostly there are a few codes from the identical coordinates. What is the function to

Hello, Can anyone think of a non-iterative way to generate a decreasing geometric sequence in R? For example, for a hypothetical function dg, I would like: > dg(20) [1] 20 10 5 2 1 where I am using integer division by 2 to get each subsequent value in the sequence. There is of course: dg <- function(x) { res <- integer() while(x >= 1) { res <- c(res, x) x

Hi folks, Debian 504 64-bit What is the correct syntax to check the available of a package on R repo? > available.packages("emacs", "OS_type=linux") Warning: unable to access index for repository emacs Package Version Priority Depends Imports LinkingTo Suggests Enhances OS_type License File Repository > available.packages("emacs") Warning: unable

Hello R-experts, I have some coordinates that look like this: lat                           long 32 31.85 59 48.74 34 05.7 58 50.79 34 05.7 58 50.79 34 05.7 58 50.79 This was my GPS setting by the time of filed trip. I assume that the second column is "minute + seconds". Am i right? I am looking for a

Hello! I have something like this: test1 <- data.frame(intx=c(4,3,1,1,2,2,3), status=c(1,1,1,0,1,1,0), x1=c(0,2,1,1,1,0,0), x2=c(1,1,0,0,2,2,0), sex=c(0,0,0,0,1,1,1)) and I can easily fit a cox model: library(survival) coxph(Surv(intx,status) ~ x1 + x2 + strata(sex),test1) However, I want to

All, I installed R-2.10.1 with Readline=no. Now for some reason R does not recognize some key strokes like the directional arrows. I am not sure if Readline is the problem or not. I have tried .Cofigure with Readline = yes but it doesn't fix the problem nor do I really know if readline is the problem to start with. Has anybody else run into similar problems? Thanks, Steve [[alternative

Hi, Suppose a write a function a_fn<-function(arg1) { return(table(arg1)); } I have a column called AGE. Now I call the function c = a_fn(AGE); When a_fn is called, AGE is received in arg1. My question is, how do I access the actual name of the argument arg1? i.e, inside the function, i need to know that the actual name of arg1 is "AGE" in this case. Thanks in advance,

Is there a less cryptic way to compare three or more values? allTheSame<-c("red","red","red","red") notAllTheSame<-c(132,132,132,999) all.identical <- function(vectorToTest){ cIdentical=sum(vectorToTest %in% vectorToTest[1]) return(cIdentical==length(vectorToTest)) } all.identical(allTheSame) all.identical(notAllTheSame) Thanks in

Hello, Is it possible to extend the R lexer/parser to include multiline comments like /* acomment */ ? This way I can integrate emacs org-mode with my R code, so that I can have a table of contents, section folding, html-output of source etc. e.g /* * Display Code */ #+BEGIN_SRC R foo <- function(...){ stuff } #+end_src and so on . Thanks Saptarshi

Hello, Is there an way to easy comment of sections of code? I was thinking something along the lines of \dontrun{ codeline 1 .... codeline k } but that could be used in regular script files. When I am still working on a script, I often want to being using what is done, but I would like the parts I am still working on not to be run when I use source() on the file. I can set everything off

Hello everyone, I am attempting to write a function to count the number of non-missing values of each column in a data frame using the sapply function. I have the following code which is receiving the error message below. > n.valid<-sapply(data1,sum(!is.na)) Error in !is.na : invalid argument type Ultimately, I would like for this to be 1 conponent in a larger function that will produce

Dear all, I have a list like this: l <- list(list(a=1,b=NULL), list(a=2,b=2)) I want to find out the elements with value of NULL and replace them with NA. The actual case has a very long list, so manually find out and replace them is not an option. I can use for loop to do this, but I want to know if there is vectorized way (or other ways) to do it? Thanks -- Wincent Rong-gui HUANG Doctoral

Hello, If I want to see how, say, apply function is written, how would I be able to do that? Just typing "apply" at the prompt does not work. Thank you for help! Sergey

Hello, How would you go about handling the following situation? This is on R 2.12.0 on Ubuntu 32-bit. I have a wrapper function to lm. I want to pass in a subset argument. First, I just thought I'd use "...". ## make example reproducible set.seed(123) df1 <- data.frame(age = rnorm(100, 50, 10), bmi = rnorm(100, 30, sd = 2)) ## create a wrapper using

Hi everyone, I have been merging many big dataframes (about 80000 rows each) and I never had this problem, but now it happened to me and I want to know if someone knows what could be happening. The final dataframe has many rows, an impossible number! I have done edit(dataframe) and I saw that there are many repeated rows (all equal). Thanks for any help, Cec?lia Carmo Universidade de

I have read the R manual and help archives, sorry but I'm still stuck. How would I do a t-test with an adjusted p-value? Suppose that I use t.test ( ) , with the function argument alternative = "two.sided", and data such that degrees of freedom = 20. The function calculates a t-statistic of 2.086, and p-value =0.05 How do I then adjust the p-value? My thought is to do

Dear all, There have been a variety of discussions on the R list regarding the use of R in clinical trials. The following post from the STATA list provides an interesting opinion regarding why SAS remains so popular in this arena: http://www.stata.com/statalist/archive/2008-01/msg00098.html Regards, -Cody Hamilton
