Dear R-devel, It seems that lsfit incorrectly reports coefficients when the input matrix 'x' is rank-deficient, see the example below: ## here values of 'b' and 'c' are incorrectly swapped > x <- cbind(a=rnorm(100), b=0, c=rnorm(100)); y <- rnorm(100); lsfit(x, y)$coef Intercept a b c -0.0227787 0.1042860 -0.1729261 0.0000000 Warning message: In lsf...

Hi all, I am slowly working on a SwitchInst optimizer (http://llvm.org/PR8125) and now I am running into a deficiency of the x86 peephole optimizer (or jump-threader?). Here is what I get: andl $3, %edi je .LBB0_4 # BB#2: # %nz # in Loop: Header=BB0_1 Depth=1 cmpl $2, %edi je .LBB0...

Hi, I have encountered this error when attempting a One-way Repeated-measure ANOVA with my data. I have read the "Anova in car: SSPE apparently deficient rank" thread by I'm not sure the within-subject interaction has more degrees of freedom than subjects in my case. I have prepared the following testing script: rm(list = ls()) suppressMessages(require("plyr")) suppressMessages(require(ez)) source.fi...

Dear R-users; Previously I posted a question about the problem of rank deficiency in summary.manova. As somebody suggested, I'm attaching a small part of the data set. #*************************************************** "test" <- structure(.Data = list(structure(.Data = c(rep(1,3),rep(2,18),rep(3,10)), levels = c("1", "2", "3&quo...

...the contrast() function from the Design library: dd <- datadist(a,b,g) options(datadist='dd') o <- ols(y~a+b*g) contrast(o, list(b=1,g=levels(g)), list(b=0,g=levels(g))) Now take the situation where there are empty cells in the b x g table, so that the model is rank deficient, i.e.: m <- lm(y~a+b*g, subset=(b==0 | g!='B')) summary(m) Now there's trouble. The estimable() function and Design library do not seem to handle rank deficient models well. Here is my current best attempt to get what I want: my.coef <- function(n) {...

A recent article in the earth science literature cited below and available at http://geography.uoregon.edu/datagraphics/EOS/ points out that rainbow color schemes and mixtures of green and yellow can be troublesome for people with color-deficient vision. The authors propose alternative schemes that can be viewed and downloaded in RGB, HSV, CMYK, and RGB256 formats from http://geography.uoregon.edu/datagraphics/color_scales.htm. I have translated their RGB definitions into the hex color names given below. Ironically, their article app...

...I want to construct a gee model in R. When I ran the program, there was a warning in the output. The warning is "Beginning Cgee S-function, @(#) geeformula.q 4.13 98/01/27 gee(cbind(hyper, nohyper) ~ I(Ethnic) + I(Gender) + I(drink) + : rank-deficient model matrix" What is the rank-deficient model matrix? What should I do to solve the problem? Thanks all. Lian ______________________________________________________________________________________ 怎樣減少垃圾信？只要看到垃圾信，立即按下「這是垃圾 spam/index.ht...

...an analyze the dataset successfully in other software, including my legacy DOS version BMDP, and R's 'aov' function. I would like to use 'Anova' in 'car' in order to obtain the sphericity tests and the H-F corrected p-values. I do not believe the data are truly deficient in rank.

When I first configured and built R, I did not have the GNU readline library installed on my system, so naturally I got an R without readline capabilities. I then installed the GNU readline library, and again configured and built R. I now have an R with readline capability, but it is a deficient readline capability, providing only one-line editing capability (e.g., CTRL-A, CTRL-E, CTRL-B, CTRL-F, CTRL-D) without any history functionality (e.g., CTRL-P, CTRL-N, CTRL-R). The shared libraries, version, and history capability of R are as shown in the following logfile, where "$ "...

I am trying to use lm() for resression followed by stepAIC function. Now when i try to use to predict for some input, predict() gives a warning : prediction from a Rank deficient matrix may be misleading. As I am new to R (or to statistics) How alarming this warning may be? Regards, ____________________________________________________________________________________ The fish are biting.

Hi everyone. I am a new user of R so thanks for your help! I'm running a regression and receive an error that states that the "residuals have rank 45 < 169." What does this mean? Thanks! -- View this message in context: http://n4.nabble.com/deficient-rank-question-tp1562644p1562644.html Sent from the R help mailing list archive at Nabble.com.

...ract "notable type" anyway. Apart from all that, I'm pretty disappointed to see this as an intrinsic though. GEP is such a fundamental part of addressing in LLVM that bifurcating it into an intrinsic for either a language or an analysis seems like we'd be papering over a language deficiency. Cheers. Tim.

Hi all, I have received the following error from summary.manova: Error in summary.manova(manova.test, test = "Pillai") : residuals have rank 36 < 64 The data is simulated data for 64 variables. The design is a 2*2 factorial with 10 replicates per treatment. Looking at the code for summary.manova, the error involves a problem with qr(). Does anyone have a suggestion as to how to
