I am going to document a 10.000 lines of R code project. Before reinventing the wheel, has anyone written a function that analyzes dependencies between R functions? I am thinking of output like caller1 calee1 caller1 calee2 caller1 : caller2 calee7 : and I would like to restrict caller and callee to certain positions in the search path. My guess is, that a quick and dirty solution is

Hi all! I have a list of matrices and I want to multiply the ith element of the list with the ith element of a another vector. That is, > LL <- list(A=diag(3),B=diag(3),C=diag(3)) > vec <- 1:3 > for(i in 1:3) + { + LL[[i]] <- LL[[i]]*vec[i] + } > LL $A [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 1 0 [3,] 0 0 1 $B [,1] [,2] [,3] [1,] 2 0

I am moving this to r-devel. The problem and solution below posted on r-help could have been a bit slicker if %*% worked with multidimensional arrays multiplying them so that if the first arg is a multidimensional array it is mulitplied along the last dimension (and first dimension for the second arg). Then one could have written: Tbar <- tarray %*% t(wt) / rep(wti, each = 9) which is a bit

# polygon ignores requests to have its border transparent, look at par(bg="transparent") plot(c(0, 3), 0:1) polygon(c(0, 1, 1, 0), c(0, 0, 1, 1), border=NA, col = 0) polygon(c(1, 2, 2, 1), c(0, 0, 1, 1), border="transparent", col = 0) polygon(c(2, 3, 3, 2), c(0, 0, 1, 1), border=0, col = 0) # a quick fix for erase.screen() is the following erase.screen <- function (n =

Hi, I am doing my first steps with R. This worked so far: - Installed R1.5.1 from binary distribution - Installed SJava 0.62.8 from binary distribution - Executed Java statements within R Problem: If I call R from Java, I get an UnsatisfiedLinkError: RInterpreter.DLL not found. This DLL is completely missing, I searched all drives for it. In "Calling R from Java" I found a hint:

R: how multiplying y-axis ticks value by 100 (without put the % symbol next to the number) here:? plot (CI.overall, curvlab=c("Discharge", "Death"), xlab="Days", las=1)? P.S. So instead 0.00, 0.20 etc. the 0, 20 etc. Thank you in advance, Nic [[alternative HTML version deleted]]

Hi, I would like to get guidance as to how to write code in R that can deal with the following situation: v1 is a vector containing a sequence of numbers (Ex. 1:10) I want to store the sequence of numbers resulting from multiplying the first and the second element in the vector, then the product of the 1st, 2nd and 3rd, then 1st,2nd,3rd and 4th and so forth until all the elements in the

Hi Nic, Have a look at axis.mult in the plotrix package.

HI, As I'm trying to compute Taylor series, I'm having problems in adding and multiplying unevaluated expressions. I searched for a solution but found none. my Taylor function works fine for evaluating functions as you can see here: rTaylorVal=function(exp,x0,dx,n) { ls=list(x=x0) newexp=eval(exp,ls) exp0=exp for (i in 1:n){ exp0=D(exp0,"x")

Dear R-users, I am working on a problem that I am currently not able to solve efficiently. It is about multiplying one column of a matrix with only a certain number of rows of another matrix. Let me illustrate my problem with an example: n.obs = 800 n.rowsperobs = 300 n.param = 23 Designmat = matrix(rnorm(n.obs*n.rowsperobs*n.param),ncol=n.param) Betamat =

Hi, It might be a trivial question but how do you store matrices of different dimensions read from a file or in a loop together? The best solution might be a list but I don't store the first matrix  correctly:  m = rbind(c(1,2),c(3,4),c(5,6)) t=rbind(c(1,2),c(5,6))  l = list(m) > l = list(l,t)    #I assumed that at the begining I don't have m and t at the same time to do list(m,t),

Dear R-users, has anybody combined the glm function with the Newey-West estimator of variance, similar as in Stata 7.0? I'd like to estimate corrected standard errors within a logistic regression model, taking into account the auto-correlated binary observations within individuals. I use R1.5.1 on Mac OS X (10.2). Thanks, Christof

Hi, i really positive surprised when i found the "get.hist.quote" but didn't now why i get with the examples from Online-Help errorMessages. Perhaps their is a problem with POSIX and my OS WIN2000/R1.5.1 ? Thanks for advance & regards,Christian $ ibm <- get.hist.quote(instrument = "ibm", start = "1998-01-01") trying URL `
