Using strptime() and other functions for dates has been very helpful with the kind of data I often work with. However, I haven't found out how time as such should be specified. All my attempts result in time *and* date: >treatment_time<-c("01:02:03","02:03:04") # hours:minutes:seconds >time.2<-strptime(treatment_time,format="%H:%M:%S") >time.2 [1]

I wonder if anyone could help me find an expression for skipping the last missing values in a vector? The kind of material I have is something like x<-c(23,12,NA,23,24,21,NA,NA,NA) I would like to skip the last NA's, but not the ones in between other vallues. Any hints? (Why not do this by simply take x[1:6]? I have several vectors a couple of thousand observations long with varying

I have this typical problem of joining a number of vectors with similar names - a1, a2,..., a10 - which should be concatenated into one. Using c(a1,a2,a3,a4,a5,a6,a,a8,a9,a10) naturally works, but I would like to do it with less manual input. My attempts to use paste() gives a vector of the vector names, see below. The question is how to do the the concatenation? Any suggestions?

Is there any neat way to add a curve (frequency function or the like) to a histogram or other plots? I haven't found one yet... Robert

In my orgainzation, the people resonsible for the network are not that keen on setting up new software, so when I asked them to set up emacs or some other common R editor, I was told to have a look at ConText. This editor is avaliable in the network, and there is some R support. Special commands are highlighted and such, but the most important part, sending commands writtten in a ConText window

I would like to have some function for getting an overview of the variables in a worksheet. Class, dimesions, length, number of missing values,... Guess it wouldn't be that hard to set up such a function, but I guess there are others who have made it already. Or is it already a standard feature in the base package? Any suggestions? Robert

Every now and then I realize that my attempts to document what all dataframes consist of are unsufficient. So far, I have been writing notes in an external file. Are there any better ways to do this within R? One possibility could be to set up the data as packages, but I would like to have a solution on a lower level, closer to data. I can't find any pointers in the standard manuals.

Is there a way to do text plots in R? I'd like to do some simple XY plots in R with the output in text (ascii). For example, with gnuplot I can do the following: echo 'set terminal dumb ; plot sin(x)' | gnuplot To generate a simple sin wave. Since I connect to a remote Linux machine using SSH, being able to generate a rough idea of what a plot will look like in text would be

I have tried to find a neat way to include graphs from R in LaTeX documents, but have not succeeded (I work with a WinEdt/MikTeX combination). The two roads I have stumbled along so far are the following: *Generate postscript files and convert them into EPS files by means of GhostScript or other not so straightforward tools. *Generate pictex files and include these. None of these solutions have

Hi, many thanks for all suggestions as to shading of areas. Now to another small detail: how do I add items to the x-axis? Given a plot of "dnorm", I'd like to add some text to the x-axis, preferably with a corresponding tick mark. Imagine the typical \lambda demarcating a tail area. So far, I've only been able to add text in the plot region, not in the one of the axes.

Hi all, I've got this graphics question which really should be easy. I want to shade an area between bounds under a curve. A suitable beginning seems to be the following: > plot(dnorm,-4,4) > segments(-4,0,4,0) > segments(-2,0,-2,dnorm(-2)) > segments(2,0,2,dnorm(2)) It is the area between -2 and 2 which I want to shade (or something similar). Hints anyone? Robert

Dear all in vorbi I spec, the function of render line is a integer line drawing algorithm similar to Bresenham's algorithm, I think bresenham's algorithm is more optimum than vorbis's algorithm? Why vorbis does not adopt Bresenham's algorithm? I hope someone can talk about it! thx all? luooq 2005-01-26 -------------- next part -------------- A non-text attachment was

Hi, I am maintaining a port of rsync (https://github.com/perlundq/yajsync) which is GPL:ed of course. The main purpose of the project is to provide a Java API library for the rsync protocol. It would therefore be really nice to be able to use LGPL as the license. But in order to do so I would first have to get a list of all the individual contributors to rsync and then be able to contact them
