Substituting the extracted coefficients into the formula, exctracted from the result of nls()
Dear all, Here I come with another stupid question. Suppose I want to use nls() to fit a series of data (here modelled by generated points), then plot the points and the fitting curve. I figured out some way of doing it: x <- runif(1:20, 0, 10) y <- 0.1*x^2 - rep(3, length(x)) + rnorm(length(x), sd = 0.5) yfit <- nls(y ~ a*x^2 + b*x + c, start = list(a = 1, b = 1, c = 1),

subsetting objects
I want to be able to exctract a matrix from a data frame that contains repeated measurements for individuals. i.e I want to exctract the second observation for each individual in the study. Is there a way of doing this? I guess what I am trying to ask is if there as a multidimensional version of aggregate() as in aggregate(data, list(data[,"ID"]), function(x) x[2,]) but aggregate will

reshape (a better way)
Hi, I am using the NLSY79 data (longitudinal data from the Bureau of labour stats in the US). The extractor exctracts this data in a "wide" format and I need to reshape it into a long format. What I am doing right now is to do it in chuncks for each and evry variable that is varying and then I merge the data together. This is taking a long time. my question is: How do I specify that

create matrix
...th '1' for 'survival'. I thought of creating matrices for each individual, adding first one column 'survival' containing zeros to the original dataset, then creating matrices with data = 'the vector containing all elements of an individual/row' ([1,], nrow = [a,b], exctracting the element for longevity, and then with byrow = TRUE letting the data be filled in by row. At the end I would have to set the last element in 'survival' to '1', and then combine all matrices into one single one. So far I've used Excel to create these datesets manually, but wi...

List or matrix of object
Hi everyone. Is it possible in R to create a matrix or a list (vector) or R object. For instance, I have f1 <- function(x) sqrt(x%*%x); f2 <- function(x) (2x+1); I would like to do something like L <- List(); L[1] = f1; L[2] = f2; So, is there a way to create matrix or vector that can contains R object.

Read data from Excel
A client of mine has a ton of data stored in Excel spreadsheets. I''m building a web application for her (backed by a real db of course) and want to import all that data. Is there a library available to read data from Excel? Is there an easy way to upload the spreadsheets and then read the data? Thanks, Ken Kousen -- Kenneth A. Kousen, Ph.D. President Kousen IT, Inc.
