Cancor
Dear R's! I am strugling with cancor procedure in R. I cannot figure out the meaning of xcoef and of yxcoef. Are these: 1. standardized coefficients 2. structural coefficients 3. something else? I have tried to simulate canonical correlation analysis by checking the eigenstructure of the expression: Sigma_xx %*% Sigma_xy %*% Sigma_yy %*% t(Sigma_xy). The resulting eigenvalues were the same

Interpreting canonical correlation (cancor) results
Hi, from what I understand about the canonical correlation function 'cancor', it looks for correlations in two sets of variables, each represented in matrix form. Right? Sounds exactly like what I need. I have tried the following but I am not sure how to interpret the results. AudioPCs <- c(ArTHarF0PCA$x[,2], ArTHarF1PCA$x[,2], ArTHarF2PCA$x[,2], ArTHarF3PCA$x[,2],

about cancor.R
Hello, I'm a beginning user of R, now I have a question about canonical correlation analysis (cca). In R,there is a function "cancor.R" used for cca; For example X(n*p1) and Y(n*p2)are the two matrix to be analyzed. In the example given by R, when n> max(p1,n2), cancor(X,Y) works; but when n<p1 or n<p2, cancor(X,Y) doesn't work well because cancor$cor == 1; how to cope

Plot of Canonical Correlation Analysis
Dear all, I didn't find any graphical solution in the package "mva" to plot the canonical scores from a CCA (canonical correlation analysis). Does anybody knows how to plot or has anybody already programmed : - the map of the canonical scores, - the graph of the canonical weights, - the correlation circle i.e. the canonical loadings ? Thank you for help ...

bug on cancor (PR#116)
When I use the function cancor of mva package, I found that it doesn't work when one of the matrix has only one column, or both have only one column. The function in Splus 5 with the same name works under those situations. The version of R I am using is 0.63.2 (released on Jan., 1999) on Solaris.

how to suppress the intercept in an lm()-like formula method?
I'm trying to write a formula method for canonical correlation analysis, that could be called similarly to lm() for a multivariate response: cancor(cbind(y1,y2,y3) ~ x1+x2+x3+x4, data=, ...) or perhaps more naturally, cancor(cbind(y1,y2,y3) ~ cbind(x1,x2,x3,x4), data=, ...) I've adapted the code from lm() to my case, but in this situation, it doesn't make sense to include an

Coefficients in a polynomial glm with family poisson/binomial
Dear R-users When running a glm polynomial model with one explanatory variable (example Y~X+X^2), with a poisson or binomial error distribution, the predicted values obtained from using the predict() function and those obtained from using the coefficients from the summary table "as is" in an equation of the form Y=INTERCEPT+ XCoef x X + XCoef x X^2, differ considerably. The former are

Alternative to cxy in R
good morning to the R-help list!, I would like to ask if there is an alternative to the S ploting parameter "cxy" in R. I am trying to port some S code to R that makes use of this "cxy" parameter to scale the graphics, and I don't find this parameter in help(par). thank you, IOsu ------------------------------------------------------------------------------- Jes?s

Implement VLIW Backend on LLVM (Assembler Related Questions)
Hello, I want to implement LLVM backend for a specific VLIW hardware. I am working on defining its instruction set, and assembly language. The hardware has two pipelines, int and float. Each pipeline can do 3 operations/cycle, 3 operations forms an instruction. One of the Integer Instruction looks like this: add Ri, Rj, Rk; add Rl, Rm, Rn; add Ro, Rp, Rq An int instruction and a float

Finding the "height of a line of text" for axis
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

Character height & width in user co-ordinates
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.

<= returns wrong result? Why
Dear all, Does anybody know the probable reason why <= gives false when it should give true? These two variables are of the same type, and everything works in the cycle but then it stops when they are equal. this is the output result > Rk[47] <= RB[21] [1] FALSE > Rk[47] [1] 0.002842007 > RB[21] [1] 0.002842007 Thanks a lot.

[RFC] Interprocedural MIR-level outlining pass
Hi Violeta, I compiled with clang -Oz and clang -Oz -mno-red-zone for comparisons against Oz and clang -O0 and clang -O0 -mno-red-zone for comparisons against a default clang. I unfortunately don’t have the clang commit I worked with on my home laptop, and don’t have access to the computer I was using at Apple, so I can’t help you there.

Error in colMeans ... what's wrong with my data?
Having searched and searched I still haven't found what's the problem with my data (I've attached the relevant file). Every time I tried to use the CANCOR-Function I got error messages. So I turned to check my two sets of variables separately by using the "colMeans"-Function. With one set no problem .. but with the other. My input : > struktur <-

Background color(s) for groupedData plot
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

how to suppress whiskers in a bwplot?
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).
