Re: [R] Interesting quirk with fractions and rounding

The subject is messy. I vaguely remember learning this stuff on my first numerical analysis course over 40 years ago. The classic reference material (much newer, only 25 years old) is: What Every Computer Scientist Should Know About Floating-Point Arithmetic, David Goldberg, ACM Computing Surveys,

[R] Wireframe plot inside a function

Consider the following example: library("kdecopula") library("mvtnorm") pobs <- function(x) rank(x) / (length(x) + 1) n <- 1000 sigma1 <- diag(x = 1, 2, 2) x1 <- rmvnorm(n, sigma = sigma1) xx1 <- apply(x1, 2, pobs) cop1 <- kdecop(xx1) eps <- 0.8 sigma2 <- matrix(c(1, eps, eps, 1), ncol = 2)

[R] Question about logspline

I have a dataset with values of limited precision. I am trying to plot its density using package logspline. The logspline() call with default parameters causes oscillations in the density plot. My solution was to fuzzify the input values, using function: > fuzz <- function(x, prec) x +

[R] Help with saving user defined functions

I can't figure out how to save functions to RDS file. Here is an example what I am trying to achieve: > t <- rnorm(100) > cdf <- ecdf(t) > cdf(0) [1] 0.59 > saveRDS(cdf, "/tmp/foo") > Save workspace image? [y/n/c]: n [gtrojan@asok petproject]$ R > cdf <- readRDS("/tmp/foo") > cdf Empirical CDF

[R] rgl does not plot

I have installed package rgl without any problems. I can load the library, issue commands from console without any errors showing up, however I can't get anything plotted. Example session: > library(rgl) > plot3d(rnorm(100), rnorm(100), rnorm(100)) > rgl.quit() > library(rgl) > .check3d() glX 1

[R] gamlss question

What is the recommended way of accessing distribution parameters (mu, sigma, ...) from the model fit? The indention is to use those values in d/p/q/r calls. I came out with a wrapper gamlss_fit <- function(x, family) { fit <- gamlssML(x, family = family) mu <- fitted(fit, "mu")[1]

Re: [R] R cannot access the web?

I am sorry guys neither of those things have worked! I am at an absolute loss! I did contact the HPC server managers to see if they are willing to update the version of R that's accessible to us - but I am not sure if or when they will make the changes. -- View this message in context:
