I performed an aov() analysis and got the following results: Df Sum Sq Mean Sq F value Pr(>F) block 1 0.0040 0.0040 0.3282 0.5672 Residuals 269 3.2766 0.0122 Can anyone tell me how to extract the F value column and Pr(>F) column from the summary output of aov analysis?

Dear all, I am trying to get an estimate of the intercept for a linear model. In this case, I know the slope of the model, can anyone tell me how to constrain the formula in lm() so that it only estimates the intercept not the slope?

Hi I'm looking to a function in R equivalent to S-PLUS' "interp". Is there any implementation in R? If not, is there any similar interpolation function such that at the data points the interpolated values concides with the data? Thanks in advance P.J.

How would you proceed with the following problem: I have an data frame containing a table relating raw scores on an iq test to 'decile-like' scores. data<-data.frame(age =c( 8, 9, 10, 11, 12, 13, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70), pers90=c(33, 39, 43, 47, 50, 54, 54, 52, 50, 49, 47, 46, 43, 42, 39, 37), perc75=c(27, 31, 37,

Hi I'm writing my MSC and I've used R to do the data analysis. Now I want to make a reference to the program but I don't know how ! I thought of something like: Anonymous. 2001.

Dear all, I'm writing a lgrind definition for R. Lgrind is a program to produce pretty program listings for inclusion in LaTeX documents. Does anybody here have any experience with lgrindefs?

Dear all, There has been some time since I asked about interpolation in higher (>2) dimensions, and I must admit I failed to write a function to do this myself the last time, but eventually ended up doing it in MATLAB. I tried to translate the MATLAB code, but MATLAB code is so much more opaque than R (S) code, so I failed that too, mainly because I could only get one MATLAB session, I would

Dear all, I am interested by the various messages sent to the r-help mailing list these last few days about documentation on R. Yet, there are a lot of issues actually open on this topic, and it is not clear to me what is the "urgent need for documentation" on R. R comes with the 'Introduction to R' by Venables et al. I recommend the colleagues and students in my lab who are

Dear all, I have been trying to understand what runif() is telling me. I am generating lots of numbers (billions and billions (wow, I''ve dreamed about saying that for many years... :-) ), for a distribution that has the following quantile function: 1 / (2 * sqrt(1 - p)) (that is, the distribution has a lower cutoff) As you can imagine, this has rather heavy upper tail. I was

Sorry, I pasted the wrong file in earlier... this is the correct one: pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <- scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1 = "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score

I am trying to install R on a unix workstation (Sun-SPARC) but I am not sure which of the binaries to use. The only binaries available are for linux, nextstep, osf, and windows. Which one of them will work for a SUN sparc station?? Thanks. PS. I tried to compile the source code but it looks like I have a probelm with fortran. So, if I could install one of the binaries it would be a lot

Hi Rers, W/o trying to make a long story short (I hope you read that correctly), I have been working on a nice little R function ... Somewhere along the line I got an error that refers to a max function in my function (I think this is a vector vs. scalar issue): Error in max(..., na.rm = na.rm) : invalid "mode" of argument If that's not bad enough, even when I q() R and say

Why is it that when a vector contains no NAs, na.omit returns an empty vector rather than the object/vector that was passed to it? >na.omit(c(1,2,3,4)) numeric(0) in contrast ... >na.omit(c(1,2,3,NA)) [1] 1 2 3 attr(,"na.action") [1] 4 attr(,"na.action")attr(,"class") [1] "omit" Thanks, Alex --------------------------- platform

Hello I have installed R-0.90.1 on my Linux (Redhat 6.2) machine, unfortunately I am not able to use a number of commands like e.g. smooth.spline and predict.smooth.spline.

(No syntax highlighting programmability yet, but maybe soon). Anyway, I have

Hi all, I am a beginner to R, so you have a right to dislike me. I have loaded up a data matrix (664 * 28) into the R environment and wish to have a pre-written program (MAXCOV-HITMAX) analyse the data. When I run the program, I get: "Error in ncol(hitdat). Argument "hitdat" is missing with no default"; I can't seem to find much info in the manuals, etc. to help me out, so

hi, Just a very simple question: is there an R equivalent to the matlab command find(X) which returns the indices of vector X that store non-zero elements? e.g. > find( [1 0 0 1 0]) ans = 1 4 so, in R, how do I do: ans <- rfind( c(1,0,0,1,0)) so that ans is the vector c(1,4) thanks, stephen -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help
