This help list is not intended for solving your assignments. But you're honest about it, so I'll describe for you shortly what the output is. How to interprete that output is up to you. see inline comments. On Sun, Jun 6, 2010 at 12:38 PM, wojak121 rotworm...@op.pl wrote: I'm sory for my weak

Re: [R] Cumulative frequency percentage and library (equate)

For cumulative frequencies, see ?cumsum https://stat.ethz.ch/pipermail/r-help/2007-September/141499.html To access the _package_ equate, you have to install it first. Then, you just use library(equate). Cheers Joris On Sun, Jun 6, 2010 at 3:26 PM, ying_chen wang gracedrop.w...@gmail.com wrote:

Re: [R] paste together a string object later to be utilized in a function

Wild guess, but it looks like you are looking at : ts - list(a=1:5) names(ts$a) - letters[1:5] v-paste(rep(names(ts$a[,1:b,]),ts$a[,1:b,]),sep=) sapply(v,function(x){eval(parse(,text=x))}) $`rep(names(ts$a[1]),ts$a[1])` [1] a $`rep(names(ts$a[2]),ts$a[2])` [1] b b

Re: [R] Loading an image/picture (png/jpeg/...) to screen...

There might be a way doing that in R, but if you really need to take measures of a picture in some standardized way, I suggest you take a look at ImageJ. More than R that seems the right tool for the job. Some people have been experimenting with connecting ImageJ and R, but even without connection

Re: [R] prettyR

Very simple as explained in the help files: X - 1:5 X [1] 1 2 3 4 5 add.value.labels(X,letters[1:5]) [1] 1 2 3 4 5 attr(,value.labels) a b c d e 1 2 3 4 5 X [1] 1 2 3 4 5 X didn't change. X - add.value.labels(X,letters[1:5]) X [1] 1 2 3 4 5 attr(,value.labels) a b c d e 1 2 3 4 5 X

Re: [R] R2HTML problem

Take a look at eclipse : http://www.splusbook.com/R_Eclipse_StatET.pdf And yes, your program should work. The editor doesn't do anything else but sending your code to R. It is R that decides what to do with it. Cheers Joris On Sun, Jun 6, 2010 at 7:25 PM, RGtk2User iagoco...@gmail.com wrote:

Re: [R] Prediction in discriminant analysis

You use the function predict for that. You give a data frame with the new observations, and make sure the variables have exactly the same name. # run example library(MASS) Class - as.factor(rep(c(A,B,C),each=30)) X1 - c(rnorm(30),rnorm(30,3,2),rnorm(30,-3,1)) X2 -

Re: [R] What is the largest in memory data object you've worked with in R?

You have to take some things into account : - the maximum memory set for R might not be the maximum memory available - R needs the memory not only for the dataset. Matrix manipulations require frquently double of the amount of memory taken by the dataset. - memory allocation is important when
