Hello, I might have missed it in the help pages, but I cannot find if something exits in a package to make discriminant analysis.

I'm probably misunderstanding something in "Writing R Extensions" version 1.0.0. In the chapter on the R API, section 4.7, it is stated that the functions listed in R_ext/Linpack.h are available to users' Fortran code. I am developing a developing a library of ode solvers, based on lsoda and ddassl, and which in turn call some routines from linpack and double precision blas. I

Peter, As I understand your Q. You probably have data that is similar to each other like stock Prices for all RHS variable. In that case the difference between corr and cov is not significant; however, if your RHS contains totally dissimilar variables it matters a great deal. If x1 income, x2 job type, x3 Education level, etc..., then taking cov of these variables would not be desireable

Hi all, Probably a simple question, but I just can't find a simple answear in the older threads or anywhere else. I've added some new vectors as columns in a data frame using cbind(). As they're all put as the last columns inte the data frame, I would like to move them to specific positions. How do you do to change the position of a column in a data frame? I know I can use

Hi all, I've tried to make a 3D plot, but have run into some problems. I'd like to have a plot that I can rotate interactively using the mouse, which is possible using the plots3d {R.basic}. However, I would like to change the symbols used as the points, but there's no pch in plot3d(). If I use the Scatterplot3d package, I'm able to change this, but not able to rotate

Hi all, I've got some problems when changing the trellis settings for the lattice plots. The plots look exactly as I want them to when calling show.settings() as well as when plotting them in the graphical window. But when printing to a pdf file, none of the settings are used!? Does anyone know what might have happened? Because the when changing the trellis settings, these should remain in

Hi everyone, Can I suggest an additional output component in cancor, from package mva? It would be useful to have the number of canonical correlation vectors, equivalently the rank of the covariance between x and y (label "rank"). This would usually be min(dx, dy), where dx and dy have already been computed for the svd function, but there might be situations where it was less than

Another naive stats question. I'm trying to better understand what boxplots are telling me. I think what I see is the median and the boundaries of the 1st and 3rd quartiles. The whiskers represent the range of the data unless there are points which are outside "range" (default: 1.5) times the distance from the median to that quartile. Is that right? I've read the

Howdy! I need to calculate partial correlations and I just can't find out how to do that with R. Can anybody help?

Is there an equivalent to the S-PLUS par()$cxy in R? Also, is it possible to get notice taken of some equivalent of \n in R when using text()? For what it is worth I am using RW-0.64.1.

Hi everybody, I'm using the method described here to make a linear regression: http://www.apsnet.org/education/advancedplantpath/topics/Rmodules/Doc1/05_Nonlinear_regression.html > ## Input the data that include the variables time, plant ID, and severity > time <- c(seq(0,10),seq(0,10),seq(0,10)) > plant <- c(rep(1,11),rep(2,11),rep(3,11)) > > ## Severity

Hi, Earlier this year I "upgraded" from wine 20010510 to 20011226 in order to see if some kind of resource leak was fixed which caused screen redraws to get progressively slower and slower and slower and slower, .... That was fixed but there seemed to be a significant number of graphics and UI regressions. I've just upgraded to 20020228 to see if things were any better and within

Hello: I am using rpart and would like more background on how the splits are made and how to interpret results - also how to properly use text(.rpart). I have looked through Venables and Ripley and through the rpart help and still have some questions. If there is a source (say, Breiman et al) on decision trees that would clear this all up, please let me know. The questions below pertain to a

Hi, I have two catagorical vectors like this; x = c(1, 2, 4, 2, 1) y = c(2, 4, 2 ,4, 1) I want to set up a barplot with the catagories 1-4 horizontally and number of occurances vertically for each vector x,y. I've tried boxplot(table(x,y), beside=T) and boxplot(c(x,y), beside=T) among others, but can't get it to work...Any ideas? I'd apppreciate any help

I would like to draw only the ticks of an axis, but not the axis itself. I don't think this can be done using axis(), so I am trying to write a cut-down version in R, which only draws ticks. The point at which I am stuck is that the length of a tick is set by par("tcl") as a fraction of the "height of a line of text". So I would like to draw a line whose length is also

I often use something like old.par <- par(set someting) on.exit(par(old.par)) but in R 1.7.0. I now get warnings: > old.par <- par() > par(old.par) Warning messages: 1: parameter "cin" can't be set in: par(args) 2: parameter "cra" can't be set in: par(args) 3: parameter "csi" can't be set in: par(args) 4:

I've been using par() to check the graphics parameters associated with both plot(<fitted linear model>) and plot(<grouped data object>). AFAIK the only differences are in the $cxy, $usr, $xaxp, and $yaxp parameters but the background color for the grouped data plot is grey while the linear model plot has a white background. When I've tried par(bg = "white") prior to

Hi, I'm newbie with R and don't really know how to add a median line to each of the groups that is not all the plot long. Here is a small working code that i have adapted for my purpose. If somebody could tell me how to draw median lines on each group and not all plot long. ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14) trt <-

dear R-help, i have looked carefully through the R-help archives for information on how to suppress whiskers in a bwplot. someone asked this question a while ago, but the answer he received is not available in the archives. but i did manage to get my hands on a panel function (called "my.panel") that is supposed to do this (the function is reproduced at the end of the email, below).

hi, I have a barplot with six clusters of four bars each. Now I would like to add the exact value of each bar as a number above the bar. I hoped to get some tips here. I could simply add text at the different positions, but I don't understand how the margins on the x-axis are calculated (how can I get / calculate the x-ticks of a barplot?). Also I would like to code this flexible enough so
