similar to: bus error /segmentation fault from 'approx' (PR#7166)

Full_Name: joerg van den hoff Version: 1.9.1 OS: MacOS and SunOS Submission from: (NULL) (149.220.4.88) follow up to ID 7166. something like approx(c(1,2),c(NA,NA),1.5,rule=2) crashes 1.9.1 on both systems (MacOS 10.3.5.: bus error, SunOS 5.9: segmentation fault) even if xout is within given x range (as in example above) where rule=2 seems not be relevant anyway.

hi, did'nt see anything in the archive: map('world',pro='rectangular',para=0) yields a strange artifact (horizontal bar) extending over the whole map at a certain latitude range (approx 65 deg. north), whereas map('world',pro='rectangular',para=180) (which should be the same) does not show the artifact. the artifact shows up in other projections as well,

I have encountered the following problem: I need to extract from a list of lists equally named compenents who happen to be 'one row' data frames. a trivial example would be: a <- list(list( df = data.frame(A = 1, B = 2, C = 3)), list(df = data.frame(A = 4,B = 5,C = 6))) I want the extracted compenents to fill up a matrix or data frame row by row. the obvious thing to do seems: b

I need to make plots similar to those produced by the s-plus rayplot function but can't seem to find it in R. These 'vector maps' plot a ray or vector at each specified location. Is there something similar in R ? --Rich Richard Kittler AMD TDG 408-749-4099

I recently coded a recursion algorithm in R and ir ran a few days without returning any result. So I decided to try a simple case of computing binomial coefficient using recusrive relationship choose(n,k) = choose(n-1, k)+choose(n-1,k-1) I implemented in R and Fortran 90 the same algorithm (code follows). The R code finishes 31 minutes and the Fortran 90 program finishes in 6 seconds. So the

I need to extract identically named columns from several data frames in a list. the column name is a variable (i.e. not known in advance). the whole thing occurs within a function body. I'd like to use lapply with a variable 'select' argument. example: tt <- function (n) { x <- list(data.frame(a=1,b=2), data.frame(a=3,b=4)) for (xx in x) print(subset(xx, select = n))

If object is user defined is: object$df.residual the same thing as df.residual(object) This is my first time to encounter the $ sign in R, I'm new. I'm reviewing "summary.glm" and in most cases it looks as though the $ is used to extract some characteristic/property of the object, but I'm not positive.

I raised this question quite some time ago but it quitly went down the river. I'll give it a second try (before keeping my modified version of matplot for ever...): matplot supports vectors (and/or character strings) for a number of arguments namely `type', `lty', `lwd', `pch', `col', `cex'. all of them act consistently in such a way that the first entries are used

hi everybody, I noticed the following: in one of my scripts 'layout' is used to generate a (approx. square) grid of variable dimensions (depending on no. of input files). if the no. of subplots (grid cells) becomes moderately large (say > 9) I use a construct like ###layout grid computation and set up occurs here### ... opar <- par(no.readonly = T);

hi list, used versions: 2.12.1 and 2.14.0 under ubuntu and macosx. I recently stumbled over a problem with `nls', which occurs if the model is not specified explicitly but via an evaluation of a 'call' object. simple example: 8<-------------------------------------------------------------------------------------- nlsProblem <- function (len = 5) {

This is R1.9.0, windows XP I run across the following: It is admittedly silly, but it shouldn't segfault: test <- list(y=1:100, x=rep(NaN, 100)) approx(test, xout=rep(NaN, 10)) Bombs! Kjetil Halvorsen

Readers, Am trying to use the function 'approx' to interpolate time series data sets: data1: 01:23:40 5 01:23:45 10 01:23:50 12 01:23:55 7 data2: 01:23:42 01:23:47 01:23:51 01:23:54 The objective is to obtain interpolated values of 'data1' column 2 (5, 10, 12, 7) for the times shown in data2. Tried the following command but received the error shown:

I'm trying to get a Qwest PRI configured and working with my lab Asterisk server. They said that the switchtype is 5ess and the signaling is pri_cpe.

Hello, I am looking for a highly efficient matrix version of linear interpolation (like approx). As an example I have data like follows: x<-data.frame(time=1:20, x=(1:20)/10, y=runif(20)) t <- seq(1.5, 15.5 ,by=0.5) # and I found the following solution: nam <- names(x) app <- lapply(x[2:3],approx,x=x$time, xout=t) r <- c(1, 2*(1:(ncol(x)-1))) x.new <-

Hi, Bit of a newbie here, I've checked the FAQ, and some srchives, but haven't found an answer. I have a Windows DTP application, which runs quite well under wine 9.0 (Mandriva Linux 2005SE), but when tryimg to print, dumps with a stack backtrace. So I thought I'd try printing from the wine-supplied notepad; this doesn't even come up with a printer list. I can't believe

Dear all; I have a dataframe with several columns. The columns are the elevation, volume and the area of the cells (which were placed inside a polygon). I have extracted them from DEM raster to calculate the volume under polygon and the elevation for a specific volume of the reservoir. > head(x6,2) Elevation Vol Area V_sum A_sum 1 2145 13990.38 85.83053 13990.38

Hi! I am currently using Sweave for writing my bachelor thesis - and I have a problem: I am using a LaTeX style (report) with quite big margin spaces. The Sweave generated LaTeX code "floats" into the margin - and it looks ugly. The text is blocked and fine... then there comes some flattering code running over the margin... and blocked text again. Considering the LaTeX output, I guess
