[R] Defining and running a simple function

I am trying, with extremely limited success, to get the R software to do some simple computations. Specifically, I defined a test function as follows: fn - function () { hw - hello world hw s - seq (0, 0.98, 0.02) s } The output should just be the words hello world, followed by a

[R] Finding the format of an object redux

at the documentation, it just tells me to look somewhere else. Is there a function f such that f (obj) will tell you a little bit about the format of the object? Tom Thomas L. Jones, Ph.D., Computer Science __ R-help@stat.math.ethz.ch mailing list https

[R] Extracting the results of a gam smooth

I am conducting a gam smooth and having a devil of a time getting out the answers so I can work with them. Here are the two lines of code: model - gam(y~lo(x, span=0.75, degree=2), family=poisson) resp_pout - predict (model, data.frame (x=x), type = 'response') The problem comes when I try

[R] loess smoothing question

I am trying to smooth a dataset with evenly spaced values of x, perhaps using loess smoothing or something similar. However, the y values are hypergeometrically distributed; I think I want to use a logarithmic link function. It falls under the general heading of non-parametric regression. The

[R] An embarrassment of riches

I have a dataset which I am trying to smooth, using locally weighted regression. The y values are count data, integers with Poisson distribution, and it is important for the regression function to know this, since assuming a Gaussian distribution will lead to substantial errors. It is a time

[R] Newbie question--locally weighted regression

I have a dataset, a time series comprising count data at five minute intervals. These are the number of people who voted at a particular voting place during a recent election. The next step is to smooth the data and estimate a demand vs time-of-day function; the problem is of interest in

[R] Question about predict function

I am working with a non-parametic smoothing operation using a Generalized Additive Model. It is a bivariate data set. I know how to do the smooth, and out comes a nice smooth curve. Now I want to find the value of the smoothed curve for several values of x (the abscissa). This can be done

[R] go or goto command

Some computer languages, including C, have a go or go to command which can be used to shift control to a different part of a function. Question: Does the R language have a corresponding command? (Yes, I am aware that it can be abused; but, in the hands of a good programmer, it is simple to

[R] Getting and using a function

I am trying to do what is perhaps the most basic procedure which can be done with the R software. Under Windows XP Home Edition, I want to get a copy of the function gam, then put it in and use it. I intentionaly use informal terms, rather than technical terms whose exact meaning I might or
