I would also be very much interested in having the image.legend function in R. The Splus image.legend uses the subplot function, which doesn't seem to be available in R, so one can't copy the Splus function to R (otherwise it would probably have been done already). I greatly appreciate the flexibility of the Splus image.legend function since it allow you to put the legend where

Dear R guru's, I'd like to sort the columns of a matrix according to the elements in the first row, and in case of a tie according to the second row, etc. In case of a 3xn matrix woppa, something like colorder _ order(woppa[1,], woppa[2,], woppa[3,]) I just cannot seem to find a way to do this for a variable number of rows, e.g. if woppa has 10 or 15 rows I now manually cut and paste to

This must be a simple question but I could not find anything under the FAQ... so here goes. I am currently working on a (quite specific) set of functions I would like to place in a library. But: I'd like to keep this separate from the R source and CRAN libraries. Is there a global variable so that R searches also other directories for sources when installing libraries? BTW, this can also be

Hi all, I am not sure if someone else noticed this as well, but the combination of piechart plots and save.plot does not work correctly. The labels and tickmarks are plotted OK, but the piechart itself is placed somewhere else in the figure (when using colors) or not visible at all (if not filled). The combination with postscript("...") works, though. Two small thingies concerning pie

When I try to install R-0.64.0 on my SUN ( > uname -a SunOS ac6 5.7 Generic sun4u sparc SUNW,Ultra-5_10 ) I get after "./configure --disable-readline" and "gmake" the following errors: gcc -O2 -I../include -I../../src/include -c saveload.c -o saveload.o In file included from /usr/include/sys/tiuser.h:18, from /usr/include/tiuser.h:17,

Hi I would like to start by thanking everyone that replied. Thank you for the information, and for the comments about how or why you use it and thankx for the encouragement re my talk.... Please note that I do not claim to have ellicited a reply from all users of R, this is a quick survey not a census. I have tried to break the responces down to the following categories: Where: (hopefully

Dear R-helpers, I have performed a PLS regression with the mvr function from the pls.pcr package an I have 2 questions : 1- do you know if mvr automatically centers the data ? It seems to me that it does so... 2- why in the situation below does the output say that the optimal number of latent variables is 4 ? In my humble opinion, it is 2 because the RMS increases and the R2 decreases when 3 LVs

Dear group, I want to use the mclust package on large data, and therefore I want to use a subset in the initial clustering phase. From help(mclust): k: If `k' is specified, the hierarchical clustering phase will use a sample of size `k' of the data in the initial hierarchical clustering phase. The default is to use the entire data set. m2 is a

Hi there, I'm using R1.0.1 Windows 98. This file contains some inputs and an aov function code. Can someone check it for me? Somehow I got completely different answer when typing them in R and in Splus. Splus gives me this: > summary( Turnip.aov ) Error: Blocks Df Sum of Sq Mean Sq F Value Pr(F) Residuals 3 163.7367 54.57891 Error: Plots %in% Blocks

Dear All; While using EMclust() in the mclust package, I frequently encountered a program error. A message window popped up with the message " Rgui.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is be created." > version _ platform i386-pc-mingw32 arch i386 os mingw32

The first: if I have a vector as (1,1,3,2,1,1), which is the command that gives all the positions of the min value? From the vector of the example a would like to obtain a new vector as (1,2,5,6) that give me all the positions of the minimum value 1. The second: if I have a matrix "A" and I want to obtain a new matrix deleting a column or a row of A, what have I to do? Thank you.

Dear R-users, dear Ron I use pls from the pls.pcr package for classification. Since I need to know which variables are most influential onto the classification performance, what criteria shall I look at: a) B, the array of regression coefficients for a certain model (means a certain number of latent variables) (and: squared or absolute values?) OR b) the weight matrix RR (or R in the De

Hi all, I would like to do some QSAR analysis (quantitative structure activity relationship). I need to use some Partial Least Squares (PLS) regression, but I have not seen this option on the R-project. Is it possible to do this kind of regression on R? thank you in advance best regards, olivier [[alternate HTML version deleted]]

Hello, I am a beginner in R, and I wonder if anyone could help me with a partial least square regression in R. I have looked up the instructions and the manual from Bjorn Mevi and Ron Wehrens. However, I think I managed to write the script correctly, but I dont understand the output on the R environment, and also how to decide on the number of components to use (from the RMSEP), and also how to

Dear R-helpers, Has anybody ever tried to compare pls regression outputs from the pls.pcr R-package developped by Wehrens with outputs from the Unscrambler software developped by CAMO company ? I find very different outputs and wonder if this comes from differences between methods/algorithms SIMPLS (pls.pcr) and PLS1 (Unscrambler).

Version 1.0-3 of the pls package is now available on CRAN. The pls package implements partial least squares regression (PLSR) and principal component regression (PCR). Features of the package include - Several plsr algorithms: orthogonal scores, kernel pls and simpls - Flexible cross-validation - A formula interface, with traditional methods like predict, coef, plot and summary - Functions
