Can anyone explain what I'm missing here? max(pp1 <- package_version(c("0.99999911.3","1.0.4","1.0.5"))) ## [1] ?1.0.4? max(pp2 <- package_version(c("1.0.3","1.0.4","1.0.5"))) ## [1] ?1.0.5? I've looked at ?package_version , to no avail. Since max() goes to .Primitive("max") I'm having trouble figuring out

Hi I looked, but I didn't find it: I need an array [0 to 101] where each element is a list (the result of Kest in spatstat). I.e. I want to do: A[2] <- Kest(pp1) A[3] <- Kest(pp2) ... A[101] <- Kest(pp100) How can I create A ? Rainer -- Rainer M. Krug, Dipl. Phys. (Germany), MSc Conservation Biology (UCT) Department of Conservation Ecology University of Stellenbosch Matieland

I'm trying to obtain numerical derivative of a probability computed with mvtnorm with respect to its parameters using grad() and jacobian() from NumDeriv. To simplify the matter, here is an example: PP1 <- function(p){ thetac <- p thetae <- 0.323340333 thetab <- -0.280970036 thetao <- 0.770768082 ssigma <- diag(4) ssigma[1,2] <- 0.229502120

Hi all I''m hacking on a netback trying to identify whether TLB flushes causes heavy performance penalty on Tx path. The hack is quite nasty (you would not want to know, trust me). Basically what is doesn''t is, 1) alter network protocol to pass along mfns instead of grant references, 2) when the backend sees a new mfn, map it RO and cache it in its own address space. With this

Dear all, I'm looking for primary help at aggregating table() results and at writing a loop (if useful) My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period

Hi I have two processes which take with a certain probability (p1 and p2) x number of years to complete (age1 and age2). As soon as thge first process is completed, the second one begins. I want to calculate the time it takes for the both processes to be completed. I have the following script which gives me the answer, butI think there must be a more elegant way of doing the calculations

Hi, Let?s consider aux1. I wanted to order its data considering its first column as the index > aux1[1:4,] V1 V2 V3 V4 V5 V6 1 0.08506724 150 1956 15.08 233.82 463.295 14 2 0.76205323 203 1922 15.35 218.74 463.295 14 3 0.86274890 195 1835 12.54 203.39 463.295 14 4 0.37940715 152 1567 24.73 190.85 463.295 14 > aux2 <-- aux1[order(aux1[1:4,1]) , ] > aux2

Hello all, I want to read a table from a given web page. If I do something like > str="http://www...." # this is the web address > aux1 <- url(str,open="rt")# open connection > aux2 <- readLines(aux1) # read web page aux2 contains the html file. I want to extract the table from the html file. Is there a function html2R, the opposite of R2html?

Hi, I seem to be unable to get a mixed legend that has lines *or* polygons (not both). For example: ppi <- seq(0,2*pi,length.out=21)[-21] frame() plot.window(ylim=c(-5,5),xlim=c(-5,5),asp=1) polygon(cos(ppi)*4+rnorm(20,sd=.2),sin(ppi)*4+rnorm(20,sd=.2), col="green",border=FALSE) polygon(cos(ppi)*2+rnorm(20,sd=.1),sin(ppi)*2+rnorm(20,sd=.1), col="blue",border=FALSE)

I'm having an interesting/odd problem with nfs (I think). We recently (Monday/Tuesday) upgraded our file server from an ancient redhat 7.3 system to a shiny new centos 6.4 system. We don't see any issues between the other centos boxes, but things get a bit weird when we start mounting on the old solaris clients. The initial symptom was that the 'tab complete' wasn't

Hi all, I'm trying to read a data set into R, but the file is messy, so I have to do it partially. The whole data is in a .txt file, and the values are separated by a space. So far ok. The problem is that in this file, not all the lines have the same number of elements, and the reading stops. And I loose the reading of the previous lines. ex. of data set: 11 12 13 21 22 23 31 32

Many thanks to Henrik for remembering the report in Bugzilla and to Kurt for implementing the change and finding out the true number of affected packages.

That's a good find! For the R >= 4.2

Hi everyone, ? I am trying to do a horizonplot using my own time series data. I know that there is a horizonplot function in latticeExtra, but on closer examination i think that the graph itself is slightly wrong (it displays some regions as triangles and i think they should be trapezoids, and the red regions (that are below the baseline) are displayed on top of the blue areas ? while i think

This doesn't seem right; I'm using R version 2.4.1 (2006-12-18) on Mac OS and Win XP and find the same issue: > mydataframe <- data.frame(ppi=c(.5,.5),mmu=c(5,10)) > dput(mydataframe,"mydataframe.txt") > dget("mydataframe.txt") Error in attributes(.Data) <- c(attributes(.Data), attrib) : row names must be 'character' or 'integer', not

The "experimental" 4.3.0 extra placeholder feature looks like a lot of effort: ideally there would be a simpler way. I'll ask on R Core. My guess would be that the new syntax is particularly
