Dear all, I have a multiline plot with each line labeled with a different letter. But I'm not able to make the legend display the same kind of pattern '-a-', instead the letter is overwritten by the line. A simpler legend with only the letter is not very visible and the pt.bg does nothing with letters. Any idea? plot(1:10,10:1,lty=1,type='b', lwd=2,pch='a')

I just upgraded my Win7 32bits installation to 2.14.0 after deinstalling 2.12.x First thing I moved the win-library from 2.12 to 2.14 and executed a update.packages(ask='graphics',checkBuilt=TRUE) (Swiss mirror). This aborts with the console message: Error in if (any(diff)) { : missing value where TRUE/FALSE needed And the antivirus (AVG) pops up complaining that colorspace.dll

[sorry, forgot some details...] I'm using optim(param, fun, method='L-BFGS-B', lower=lo, upper=up) to minimize a certain function. Often the minimization ends with the message: ERROR: ABNORMAL_TERMINATION_IN_LNSRCH What is optim() trying to say? What have I to change in my function to make the minimization succeed? Do you think using BBoptim() instead of optim() changes anything?

I'm preparing to install 2.13, so I need a clarification about package location on disk. On window the packages I have installed are under C:\Users\mvalle\R\win-library\2.12 and the ones that come with R are under "C:\Program Files\R\library" If I execute update.packages() from the R gui, it fails because it finds e.g. Matrix as a package that should be updated but the process

On Linux 2.13 by default links cairo, so png() uses it for rendering. One of my users has performance problem, so ask if it possible to temporary disable cairo during png() rendering so it reverts to grGraphics. My workaround for now is to configure R without cairo, but this affects all users that are forced to load and use CairoDevice if they wants better quality. I want to avoid this, is it

Hi all! I have an ordered vector of values. The distribution of these values can be modeled by a sum of Gaussians. So I'm using the package 'mclust' to get the Gaussians's parameters for this 1D distribution. It works very well, but, for input sizes above 100.000 values it starts taking really forever. Unfortunately my dataset has around 4.6M values... My question: is it

Some time ago someone asked for things that make R difficult to master. Here I want to record one R behavior that took me off-guard yesterday. Moral of the story: vectorialize, but don't exaggerate. Hope it helps mario ### A very simple data frame tc <- textConnection( "prefix idx val A 1 11 A 2 22 B 1 33 B 2 44") s <- read.table(tc,

Dear all, I'm using R 2.12.0 on Windows 7 (32bits) I created a filled contour from the attached data using the following code: load('bug.RData') pdf('bug.pdf', width=14, height=7) filled.contour(o4$x, o4$y, o4$z, color=rainbow, xlim=c(4,18), ylim=c(0,35), zlim=c(14,36)) dev.off() If you look (I used acrobat reader 9.4) at the attached bug.pdf, you see an incomplete grid of

Hi all, I am trying to call the R script/ R Program via my Shell Script. I need to pass a file to the R script as an argument. When I am trying to do that I am getting error and only first line of the file is being read. Can you tell me how should I do that so that it reads the entire file in a R object so that later I am able to process the matrix operation on that file. It is a tab delimited

Hi, I have two separate questions relating to the KernSmooth package. I am using the dpik function from the KernSmooth package and receive the error Warning message: In kappam * Gcounts : longer object length is not a multiple of shorter object length I saw an earlier post , but the issue was using the bkde fxn and the person appeared to be using too small of a bandwidth.

Hello I have some strange output from R and I try to understand how R works. Could you please help me with that? temp <- rbind (c(10,1),c(99,98)) > temp [,1] [,2] [1,] 10 1 [2,] 99 98 > dist(temp) 1 2 131.6435 > sqrt(dist(temp)) 1 2 11.47360 so far so good. until the nex line: when I try to do what i did before but adding the 1/(what I did

During some experimentation in preparing R lessons I encountered this behaviour which I can not explain fully mat <- matrix(1:16, 4,4) df1 <- data.frame(mat) > mean(df1) X1 X2 X3 X4 2.5 6.5 10.5 14.5 Expected, documented > median(df1) [1] 6.5 10.5 Rather weird, AFAIK there shall not be an issue with data frame at least I did not find any in help page. I tracked it

I'm running my script using mpirun -mp 4 and using snowfall+Rmpi on Linux 64bits. I receive the following error, but apparently without consequences on the results. Any idea? I'm able to reproduce it with a minimal script (below). Seems the critical issue is the for loop. Without it no error. Thanks for your help! TERM: Undefined variable. TERM: Undefined variable. TERM: Undefined

Sorry for wasting your time with an incorrect diagnosis in my previous mail! I'm running my script using mpirun -mp 4 and using snowfall+Rmpi on Linux 64bits. I receive the following error, that terminates the run. Any idea? I'm able to reproduce the problem with a minimal script (below). If n < 16371 it completes 9 iterations without problems. Already at 16371 it dies at iteration 7

Good morning! Which is the preferred method to leave a sourced script and returning back to the '>' prompt? For example I search for certain files to be processed, but nothing should be done if they are not present. Normally I do in my script: f<-dir(pattern="qq") if(length(f) > 0) { ...process file list... } # script end But I don't like those {} encompassing

Dear all, do you know if it's available and where the "FBI Homicide" dataset? It has at least the following columns: "victim age", "homicide age".

Annoyance or feature? The fix (if needed) is simple. In the matplot code change: if

Hello! Suppose I have three charts like below. The top chart is a general overview and the bottom charts are related so some point of this chart. To make clear this relationship I want to draw a line between (4,0.9) in the top chart and (10,1) in the bottom-left one. Currently I add it manually using Inkscape on the resulting pdf file. Is it possible to add it inside R? Should I switch to other
