...(2) 40 p(3) 4 p(3) 1 p(1) 2 I cannot process these data with R because it does not like the parentheses. How can I get these to look like: p1 10 p1 3 p1 4 p2 20 p2 30 p2 40 p3 4 p3 1 p3 2 The data is in a tab delimited text file and I want to get it into a data.frame(). Many thanks in advance.

...n MATLAB, I can write: for J=1:M Y(J+1)=Y(J)+ h * feval(f,T(J),Y(J)); ... In R, I can write above as: for (J in 2:M) { y = y + h * f(t,y) ... } ---- In MATLAB, I can write: for J=1:M k1 = feval(f,T(J),Y(J)); k2 = feval(f,T(J+1),Y(J)+ h * k1 How do I write k2 in R? k1 = f(t,y) k2 = ? Thanks, /oal

A colleague pointed me to this article advocating R as a Matlab substitute. Here is the link (deliberately on two lines: http://searchenterpriselinux.techtarget.com/ originalContent/0,289142,sid39_gci902076,00.html I'm not a Matlab user, but I understand that it provides a nice front end to the Linpack collection of numerical linear algebra routines. My friend and I wonder if R can really

Dear Sir, I am a new user of R and I am doing a tast, which is: find the maximum likelihood estimate of the parameter of Gaussian distribution for generated 100 numbers by using >x=rnorm(100, mean=3, sd=1). I tried to use following Maximum Likelihood function >fn<-function(x) (-50*log((sd(x))^2))-50*log(sqrt(2*pi))-(1/2*((mean(x))^2))*(sum((x-(mean(x))^2)), but it did not work. I am

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it?
