I want to create a character vector based on the table (shortened for display) below: Where there are ones in the matrix I want the column name to appear and where there are zeros nothing, which would make the vector in this shortened case: combinations <- ("A B","A C","A E H","A F G","B C D","E G H",A C D E H","A C D F

I really like to use R for all my graphs, and as I work with stable isotopes I want to have a proper chemical notation in my plots I have looked at ?plotmath, but didn't find the answer and also searched the R website. ------------------------------------------------------------------------ -- plot(1:10,xlab=expression(^{14}*C)) # I want to have a superscript with nothing in front, but it

Dear R-gurus, I would like to zoom in a plot, e.g. I select a region on the x-axis and then I would like the ranges on the y-axis to change accordingly. Is it possible to do this with existing functions, or do I have to invent some data selection before plotting? See below a short example, where I select ylim with trial and error, which I want to avoid. Cheers, Henrik Andersson

I have been using R for a few months to plot my data, and fit statistical models and so on. It is stated that R is not only a package for statistcs and graphics but also a programming language. Currently I am working with Fortran 90 to do numerical simulations (1D reactive -transport), and subsequently visualize it in some external software (spreadsheet). As I now started using R I will plot my

Just a small suggestion since Windows have a file system not designed for command line use... Would it be possible to add the possibility of automatically adding/modifying the path to the R executables in the windows installer program? --------------------------------------------- Henrik Andersson Netherlands Institute of Ecology - Centre for Estuarine and Marine Ecology P.O.

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ... I would like to turn this dataframe to station substation time data A1 B1 t1 0 A1 B1 t2 1 A1 B2 t1 5

Hello, how can use change the plot function to change the range of axises. I want my graph from a certain range [a, b], instead of from the min to max of of datas? if i want draw a line instead of dots, should i use both plot and lines function. for example: plot(x, y); lines(x, y); things seem not working if i only use lines(x, y). Thank you so much. Cuichang Zhao Jan 25, 2005

Hi, there: When plot ann predicted results I need to indicate numbers of inputs for each column. V1 V2 V3 V4 1 86.2700 49.9380 30.7630 0.1327 2 89.5127 55.9707 33.7683 0.1186 3 91.1833 58.4670 34.5610 0.1134 matplot(t, pch = 1:4, type = "o", col = rainbow(ncol(t)),xlab = "No. of inputs ", ylab = "Mean of 6 Datasets",

Hello ! There is something quite simple I want to do with R but I found nowhere in the help how to do it. I just want to plot data which are in a matrix, every column being a data set and having the same x-axis (just an index). So for example if I have a 50 x 6 matrix I want 6 set of points on the same plot. I tried plot,new() plot(MATRIX[,1]) plot(MATRIX[,2]) ... but it replaces the previous

Hi I have a complicated plot which has a potentially large legend. What I want to do is actually create the legend in a new window. Has anyone done this before? I'd like to be able to create a window with just the legend in it, and have it so the window is just the right size etc. I'm sure someone must have done this already? If not, any tips would be welcome. Thanks Mick

Hi R users Does anyone out there have a better/quicker way of adding a factor column to a data frame based on levels of another factor? I have a (large) data frame consisting of records for individual plants, each represented by a unique ID number. The species of each plant is indicated in the column "species", which is a factor column with many different levels (species). There are

I am about to write general functions to read the output of simulations models. These model generate output files with different sections which I want to analyze plot etc. Since this will be used many people at the department I wanted to make sure that will do this in the best way. For instance I want to read a snippets of data from a text that look like this.

I'm a rank beginner with R, and I'm stumped at how to get it to work with Xemacs under Windows XP. I'm afraid there are some VERY basic questions I have here. Yes, I did read http://ess.r-project.org/Manual/readme.html. Both R and Xemacs are installed and working. The current ess files are installed in a subdirectory of my Xemacs directory. I added the R bin directory to my

Do I have the right impression that it's currently not possible to produce confidence intervals for the nls predictions using R? I had a course were we used SAS PROC nlin and there you could get intervals for the parameters and the prediction but I do not have access to SAS. Would it be difficult to implement, I tried to dig into the help pages of nls, vcov and nlsModel but I could not

I would like to display output to a tcltk window from e.g. a call to summary().

I apologize in advance for posting a question not related to R. I need references to papers that use multiple linear regression in an industrial application and also in a biological experiment. This is aimed to biologists/chemists (non-statisticans) so if anyone has written a brilliant paper where the use of multiple regression is important and also understandable to people with little

If I want to fiddle with the axes, I normally plot things like this for instance plot(1:5,axes=F) axis(2,labels=letters[1:5]) BUT, if I want to do remove the axes from a scatter plot matrix using i.e. pairs(cbind(runif(10),runif(10)),axes=F) I get Error in plot.default(x[, j], x[, i], xlab = "", ylab = "", axes = FALSE, : formal argument "axes" matched by

I would like to have arrow heads at the end of my axes, since I am plotting variable where the absolute amount is irrelevant, there is not supposed to be numbers on the axes. An imperfect example: plot(rnorm(10),bty='l',xaxt='n',yaxt='n',ylab='',xlab='',type='l') abline(h=0) Like this but without, the xaxis and with arrrowheads More like this in
