Hello, To work with xls files, check out package XLConnect. The vignette explains how to use it rather well. Also, don't use attach() It can be confusing and a source for errors. Hope this helps, Rui Barradas Em 23-06-2013 21:54, Sérgio Henrique almeida da silva ju escreveu: I created a pr

Unfortunately, there's a general no-homework rule because we never know what your instructor wants you to figure out on your own (though, a sincere thanks for admitting this was hw rather than trying to trick us like so many). That said, I think your second function, while a little clumsy, does wor

Hi R helpers! I have a question. I'm trying to create a function for an exercise. Here are the arguments I should include: x and y are numeric z is a name ("plus","minus","multiply","divide") and swap is logical. Here is what the function should do: When z="plus", then x+y is performed and so o

[R] Function in R for computing correlation matrix and covariance matrix

2009-06-03 Thread FMH
Hi, At present, i have two distinct and real values for the coefficient, which is   required in AR(2) model. Based on my revision, for distinct and real values of the coefficients in AR(2) model, the correlation structure separated by lag h can be computed by p(h) = a*z1^(-h) + b*z2^(h), where p

you can see the different methods of mean by: methods(mean) Then you can type mean.default and you will see the complete code. Bart Alphonse Monkamg wrote: > > > > > > Dear ALL, > > Does anyone know how to get the complete code program for any build-in > function > in R, e.g. when I tape

Dear ALL, Does anyone know how to get the complete code program for any build-in function in R, e.g. when I tape mean in the R-console, I get the following:  mean function (x, ...) UseMethod("mean") but I need the full mean function. Thank in advance, Alphonse.

Hi all, I'm trying to find something like the "==" operator that will work on vectors or something equivalent to SQL's "IN" function. For e.g., if I have: x <- c(1,2,3,4,5) y <- c("apples", "oranges", "grapes", "bananas", "pears") z <- data.frame (x,y) w <- c(2,4,5) I want R to return the values
