how to use \Sexpr{} with sweave
I'm trying to learn Sweave. So far things are going well with the chunks of code identified by << >>= But I'm having trouble with the in-line text use of \Sexpr. Here is a short example .Rnw file: \documentclass[12pt]{article} \usepackage[margin=1.25in]{geometry} \usepackage{graphicx} \usepackage{Sweave} \begin{document} <<test>>= pnorm(1) @ \Sexpr{2+6}

How to formulate quadratic function with interaction terms for the PLS fitting model?
I have two ideas about it. 1- i) Entering variables in quadratic form is done with the command I (variable ^ 2) - plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation = "LOO" You could also use a new variable NIR_sq <- (NIR) ^ 2 ii) To insert a square variable, use syntax I (x ^ 2) - it is very important to insert I before the parentheses. iii) If you want to

Quadratic function with interaction terms for the PLS fitting model?
poly(NIR, degree = 2) will work if NIR is a matrix, not a data.frame. The degree argument apparently *must* be explicitly named if NIR is not a numeric vector. AFAICS, this is unclear or unstated in ?poly. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom

Quadratic function with interaction terms for the PLS fitting model?
Dear all, I am using the pls package of R to perform partial least square on a set of multivariate data. Instead of fitting a linear model, I want to fit my data with a quadratic function with interaction terms. But I am not sure how. I will use an example to illustrate my problem: Following the example in the PLS manual: ## Read data data(gasoline) gasTrain <- gasoline[1:50,] ## Perform

How to formulate quadratic function with interaction terms for the PLS fitting model?
?? If I haven't misunderstood, they are completely different! 1) NIR must be a matrix, or poly(NIR,...) will fail. 2) Due to the previously identified bug in poly, degree must be explicitly given as poly(NIR, degree =2,raw = TRUE). Now consider the following example: > df <-matrix(runif(60),ncol=3) > y <- runif(20) > mdl1 <-lm(y~df*I(df^2)) > mdl2

password encryption
Hi, I enabled password encryption and NT clients were able to connect. However, Windows 95 users were not able to connect any more unless they use smbpassword to reset the password (it's not an acceptable solution for our environment). If I used "update encrypted = yes", "encrypt passwords" then Windows 95 users can login with NIS password but not for NT users. How to

Sweave \Sexpr{} advice please
Dear List, First off, my deepest gratitude to the Sweave developers: this tool has improved my quality greatly. A question in my work I use \Sexpr{} statements scalar values and the xtable package for all manner of tables. What I'd like to do is to use a vector inline, rather than a whole separate table. Something like: %%%%%%%%%%%%%%%% begin code % Latex junk % Sweave block:

Top level \Sexpr and R CMD check
I would like to create \examples{} in the manual dynamically, and while it is possible to do this with a \Sexpr at the top level, R CMD check issues a warning for it. (See below.) Is it intentional that \Sexpr is not allowed at the top level? The Rd grammar allows this, but R CMD check does not. Is there any other way to generate/modify the \examples{} section dynamically?

a rounding option for \Sexpr{}?
Hi all, Currently Sweave does not format the (especially numeric) value in \Sexpr{}, and I often have to round() the numbers explicitly, otherwise I will get more than 10 digits, which is not necessary for me in most cases. Is there a way to specify the number of digits to be kept for values in \Sexpr{}? e.g. can we make \Sexpr{} respect getOption('digits')? Thanks! Regards, Yihui --

\Sexpr{} within \examples{}
Hi all, I am trying to use \Sexpr{} within \examples{} in the manual, and it all works fine, except that I get an error and then a NOTE from R CMD check when it checks for long lines in the manual. The long line check calls `Rd2txt` with fragment = TRUE, because it only checks the \usage{} and \examples{} sections, but fragment = TRUE does not evaluate \Sexpr{}, and then an unevaluated \Sexpr{}

Sweave: \Sexpr{} inside <<>>?
Hi, Is it possible in Sweave to put \Sexpr{} inside <<>>? This is a bad example, but here goes: <<results=hide>> Age <- 5 @ <<>> x <- \Sexpr{Age} @ I'm trying to get it to display x <- 5, rather than x <- Age. It's probably so obvious I'm going to feel sorry for having to ask, just the same, I'm stumped. Any ideas? Thanks. --

Sweave \Sexpr() issue
Hi, I'm having a little issue with \Sexpr{bla} relating to the number of digits it is using to print its output. I understand that what \Sexpr{bla} does is parsing 'bla' inside R and then returns it coerced into a character string. The problem I'm having is that I'm losing control over the number of digits it's using to print it's output. For example, let's take:
