Re: [R] Error Running TinnR with R

These are some of the reasons I have stuck with version 1.19.4.7 of Tinn-R; it still works fine. On Fri, Mar 12, 2010 at 10:09 AM, stephen's mailinglist account stephen4mailingli...@googlemail.com wrote: On 12 March 2010 14:27, teck-corp d.tu...@maastrichtuniversity.nl wrote: Hi Stephen,

[R] Getting multiple matrix-values using a single command

Dear all! I'm trying to get multiple values from a matrix by using a single command. Given a matrix A A - matrix(seq(1,9),nrow=3,ncol=3) How can I get e.g. the values A[1,2] = 4 and A[3,3] = 9 with a single command and without using any loop? My first idea was to generate a row- and a

[R] Usage of apply function with two matrices

Hello, I am struggling to overcome following problem: I have matrix Vf and matrix V, which both have 3 columns and I want to create a spline function basing on coordinates from this matrices (more precisely coordinates of function nr 1: x are taken from Vf[,1] and y are taken from V[,1]

[R] Likelihood Optimization With Categorical Variables

Dear all, I have the following problem: I have been using the routine optim in order to maximize a joint likelihood (basically a mixture with modeled weights) with quantitative variables..so far so good. Now I need to plug into the model a categorical variable (namely, age classes).

[R] Exporting animation of a series of plots

Hi All, Thank you in advance for your help. I made an agent-based model in R and I plot it using image() each timestep creating a nice animation. I can't seem to find in any of the R codes a means to export the series of images so that they can be played as a movie or animation. Thank you

Re: [R] Form using R

Sounds like a job for sweave or perhaps one of the packages brew or odfWeave. See also the xtable package, perhaps. You would then be able to: -- read the latest data file -- have R produce all tabular summaries, analyses, plots -- output all the results in a nicely formatted template (report)

Re: [R] Error Running TinnR with R

I'm considering going back to that version (or switching to Eclipse) because the newer Tinn-R version requires pacakges Tinn-r and Hmisc and something is aliasing functions in xtable which blows up my Sweave runs. For the time being I'm using cut-paste. On 3/12/2010 10:41 AM, jim holtman

Re: [R] Redirect/pipe output to less

Another approach may be useful. Back in May 2003 I raised a similar query: How to divert R output into a separate X window (in Linux) where it would apear after being piped through 'less'. This has the advantage that, if you choose to do it this way, it leaves your R console untouched. I raised
