Hello, I would like to be able to plot an array on a plot, something like: |arg1 | arg2 | arg3 val1| 0.9 | 1.1 | 2.4 val2| 0.33 | 0.23 | -1.4 val3| hello| stop | test I know Rwave is good to report but don't want to use it. ?

hello all, thank you for taking the time I have a matrix A that have column names (let say n columns), I want to reduce the matrix to have just a few of those column (p colums, this is trivial), but for the lines I want only the lines such that A(i,J) is part of a list (J is fixed and known) I am sure it is very easy but I don't find it (I tryed which but it doesn't seem to work) Surely

Hello all, I looking at package dse or vars or mAr I know how to simulate a VAR(p) process, my problem is that most of those processes are unstable (not weakly stationary). Do anybody know how to generate a random VAR (or VARMA even better) process that is weakly stationary?

Hello all, my question for today is the following : I have 1. a date (in a string but straightforward to convert to any format) 2. the time as the number of milliseconds elapsed since hour 00:00:00.000 of this date. My question is : 1. Is there a in built function that can give me the date+time (as POSIX object for instance) from what I have ? -- View this message in context:

Hi guys, I am trying to shift down the "ylab" of my plot but can't find how to do it. I tried to tune "mar" but it enable more room for the labels to be displayed but it does not move to "ylab" as I would like. Is there a way with "par" to shift down my "ylab" ??

Hi there, I am trying to find an example how to use Rscript Let's suppose I want to pass 3 arguments (I don't want [options] and -e [expressions] as described in help) *on the command line myRscript.R -arg1=value1 -arg2=value2 -arg3=value3 *In the script #! /path/to/Rscript args = commandArgs(TRUE); >From what I see args is just a string, do I do things correctly ? -- View this

Hello I am looking for a special plot. Let's suppose I have *100 days and *each day I have a (1D) distribution of the same variable. I would like to plot *dates on x axis and *one distribution per date on the y axe. Do you know a way of doing it ? Cheers -- View this message in context:

Hello I am trying to write a function that would plot timeseries easily... I aim at plotting two time-series on 2 different y axis sharing the same x-axis I succeded in doing so: plotTimeSerie(x,y,y2,[a lot of other args]){ ... plot() axis.POSIXct(side=1) #here I build the x-axis points() #here I plot the first time serie related to y-axis ... axis(side=2,[some args])
