Spatio-temporal analysis of homicide rates
Dear R-listers, I would like to carry out a very basic descriptive analysis of homicides rates in Italy, taking into account both the spatial dimension (103 provinces) and the temporal dimension (10 years), but no covariates. In practice, what I would like to do is to describe spatio-temporal variation of homicide rates, identifying those combinations of province-year where the homicide rate

snowfall: sfExport apparently harmless error
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.

(correction) snowfall+Rmpi: sfExport error
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

Location of libraries in Windows
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

inconsistent output using 'round'
I am hoping for some advice regarding limiting decimal points to 3. 'Round' produces the desired results except for the 97.5% confidence interval. Any advice as to how I modify the code to obtain output to 3 decimal points for all ouput is appreciated, regards Bob Green mod.multgran <-multinom(offence ~ grandiose * violent.convictions, data = kc, na.action = na.omit)

Can I disable Cairo?
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

density() vs. KernSmooth::bkde
Any advice when to use denstity() and when the KernSmooth package bkde() to smooth a histogram? No specific problem to use either one, but I'm curious why there are two so similar implementations.

Subsample points for mclust
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

How could I terminate a script (without leaving R)?
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

snowfall: missing MPI node
Hello, I don't know if the question pertains to Rmpi, snow or snowfall. I run my job by: mpirun -np N -hostfile $PBS_NODEFILE RMPISNOW -f my-script.r --slave In the snowfall sfInit call I have to specify one less CPU respect to the mpirun call sfInit(parallel=TRUE, cpus=N-1, type="MPI") otherwise I receive an error similar to: "cluster size N-1 already

Unexpected warning from matplot

Artifacts in filled.contour+pdf
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

optim: abnormal termination in lnsrch (resend)
[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?

How to put line linking two plots
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

How to make legend with line+ character
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')

[R-sig-hpc] Error in makeMPIcluster(spec, ...): how to get a minimal example for parallel computing with doSNOW to run?

Multiple plots
Hi, I would love to make multiple histograms transposed one on another in order to show relation between the sets. I tried to write a function like this, but R tells me, that I cannot use add=FALSE in high-level commands. That's nice but I am supposed to do? rm(list=ls()) # what's wrong with underscore? #getwd("/home/matej/docs/skola/stat\_anal-cj3534/assign01/")
