Dear all R users, Is there any function to calculate sample cumulant in R for any order? I did make a search using RSiteSearch but got only cum3 function. Your help will be highly appreciated. Thanks [[alternative HTML version deleted]]

Hi, R-listers I tried to plot several graphs in a sigle x-y coordinate settings, like the following: |(y) s | ****** s | ***** s | sssssssssssssssssss |_______________________________(x) where "*" and "s" denote two diffrent plots. However, when I used plot(data1); % data1 is the data points of "*"

Hey, R-listers I was recommended to try using smooth.spline function for estimating 2-Dimensinal curve given a data set. So will you please tell me where to get this R function? Or which package provides this function? Thanks for your point. Fred

Could somebody recommend some good nonparametric statistical inference textbooks for a beginner? And what are pros and cons of each book? Nonparametric statistical methods by Hollander seems to be more difficult for a beginner, but is great as a reference, right? Are there any books that are easier to learn than Hollander's? Also, I see some books in the wiki page. I don't find the

Hey, All In principal component analysis (PCA), we want to know how many percentage the first principal component explain the total variances among the data. Assume the data matrix X is zero-meaned, and I used the following procedures: C = covriance(X) %% calculate the covariance matrix; [EVector,EValues]=eig(C) %% L = diag(EValues) %%L is a column vector with eigenvalues as the elements percent

Hey, I want to draw several plots sequently, but have to make them dispaly in one figure. So how to achieve this? Thanks. Fred

Dear R users I am R newbie creating a function that implements the poker test to test pseudo random bit generators. Iam reading the bits from a text file (1 bit per line), which causes each bit to be stored in an element of a numeric vector. What Iam trying to do is to extract a "block" of bits of arbitray size from the original vector into a smaller numeric vector and then count

hi - i just started using R as i am trying to figure out how perform a linear regression on a huge matrix. i am sure this topic has passed through the email list before but could not find anything in the archives. i have a matrix that is 2,000,000 x 170,000 the values right now are arbitray. i try to allocate this on a x86_64 machine with 16G of ram and i get the following: > x <-

I found the chapters in Engineering a Compiler (Cooper and Torczon) perfectly match the code generator of LLVM. And this paper: Lengauer and Tarjan, A Fast Algorithm for Finding Dominators in a Flowgraph, ACM TOPLAS, Vol 1 , No.1, July 1979 I also would like to know more papers/books whose algorithms are implemented in LLVM. 在 星期二 19 十二月 2006 22:13，Fredrik Svensson 写道： > Hi, > > As

Hi, As Christmas approaches rapidly I would like to get some suggestions for interesting compiler books, papers and other type of information that one can read the few slow days over Christmas. Any recommendations ? I have the dragon book, but it would be fun to read something on what is happening in modern compilers. /Fred

hi all i have a function that uses two inputs, say xdata and ydata. An example is the following, simple1<-function(xdata,ydata) { ofit<-lm(ydata~xdata) list(ofit) } say i use arbitray number for xdata and ydata such that D = x1 x2 y 1 1 10 2 6 6 3 10 7 x<-D[,1:2] and y<-D[,3] if one uses these inputs and rund the program we get the following: >simple(xdata=x,ydata=y)

Apologies in advance for a kind of long question: I've written an application called changedfiles (http://www.bangstate.com/software.html#changedfiles), which consists of two parts: a linux kernel module that reports all file operations to a device special, and a userspace daemon which can take arbitray shell action on files matching regexp rules specified in a config file. E.G.,

hello, you can use the persp() function. The shade=0.7 option is very nice. With matlab, it is possible to change of colors automaticalli with the value to be plotted. Does someone know to do that ?

I'm rusty, but not *that* rusty here, I hope. If W (=Z*Z' in your case) is singular, it can not have inverse, which by definition also mean that nothing multiply by it will produce the identity matrix (for otherwise it would have an inverse and thus nonsingular). The definition of a generalized inverse is something like: If A is a non-null matrix, and G satisfy AGA = A, then G is called

Dear R-listers, I have a dxr matrix Z, where d > r. And the product Z*Z' is a singular square matrix. The problem is how to get the left inverse U of this singular matrix Z*Z', such that U*(Z*Z') = I? Is there any to figure it out using matrix decomposition method? Thanks a lot for your help. Fred

Hello everyone, I have come across a bit of an odd problem: I am currently analysing data PCR reaction data of which part is behaving exponential. I would like to fit the exponential part to the following: y0 + alpha * E^t In which Y0 is the groundphase, alpha a fluorescence factor, E the efficiency of the reaction & t is time (in cycles) I can get this to work for most of my reactions,

I have a question which is not necessarily related to R. I want to use a distorted political map of the world with certain countries increased in size according to a certain variable (an idea similar to the homunculi usually found in psychology textbooks) to demonstrate the coverage of particular countries in a news service. Does anyone have any idea of how to approach this? I don't think
