fitting a histogram to a Gaussian curve
Hello, I am trying to fit my histogram to a smooth Gaussian curve(the data closely resembles one except a few bars). This is my code : #!/usr/bin/Rscript out_file = "irc_20M_opencl_test.png" png(out_file) scan("my.csv") -> myvals hist(myvals, breaks = 50, main = "My Distribution",xlab = "My Values") pdens <- density(myvals, na.rm=T) plot(pdens,

How to run 3D Studio 7
I used crossover to install 3DSMax 7 in ubuntu. Unlike other versions, this one is known to run with wine (and crossover). Even though the software indeed is starting and running, I'm facing trouble with directx and my ATI-graphics-card now: The viewports just don't refresh (see screenshot below). Changing to OpenGL causes ubuntu to freeze. Software-rendering doesn't work either. Are

Wine, Mac, and MDAC
Hi all, I have been searching around for the past few days for a way to emulate a MySQL database access program called ES2 (http://www.veracross.com/resources/es2-setup.html) on the Mac. I have been in contact with the developer about components that the program needs, but the communication has been slow from them, so I have been exploring on my own. I believe I am close to cracking the egg, but

what to do if residuals produced by lm() have long tails?
Hi, I am using lm() for regression analysis of my data set. My regression results look pretty good, i.e., the coefficient is significant and the p value is much less than 0.05. But when I checked the residuals, both using qqnorm() and hist(), the distribution does not look normal. It looks like the residuals have long tails. I assume that lm() uses OLS, and since one of the assumptions of OLS is

Head or Tails game
Hi, Reading about a "Heads and Tails" game in http://www.dartmouth.edu/~chance/teaching_aids/books_articles/probability_book/amsbook.mac.pdf Introduction to Probability (Example 1.4, pp. 5-8). You toss a coin 40 times. If heads, Peter wins $1, tails, he loses $1. I think I can do that ok with: winnings <- sum(sample(c(-1,1), 40, replace=TRUE)) But I have to do it 10,000 times

Mixture of Univariate Normals
Dear list, Can anyone provide a package or code for estimating the parameters of a mixture of c (c >=2) univariate normal distributions? I've tried the algorithm provided by Venables & Ripley (1999) p 263, for the mixture of two normal, but I don't find the "ms" function in R. I've used nls instead, but I'm not sure if it works the same. The data I have is very

pnorm, relative accuracy in the tails
Dear R people The function below should be decreasing, convex, and tend to zero when x tends to infinity. curve((1-pnorm(x))/dnorm(x),from=0, to=9) >From the plot we see that for x between 8.0 and 8.3 the function is fluctuating. As far as I understand, this is due to the function pnorm() not being sufficiently accurate in the tails. I am using pnorm() in a way that has probably not been

more Matrix weirdness
I think that this is because `[<-` dispatches on S4 methods only if the first argument is S4. ?"[<-" says: "These operators are also implicit S4 generics, but as primitives, S4 methods will be dispatched only on S4 objects ?x?."

[Hmisc] Latex to pdf
I would like to print some tables and figures to a PDF device on a CentOS 5 vps. However, I cannot seem to get the latex function from Hmisc working. I followed the example, and got an error: sh: xdvi: command not found. I tried installing the 'tetex-xdvi' linux package, and now it returns: Error: Can't open display. I guess the reason for this is that the machine is a VPS terminal, so

RObjectTables freezes in R 3.2.0 RC on 32bit systems
We recently started noticing freezes that appear only on 32bit systems (both linux and windows) with a relatively recent versions of R 3.2.0, including the RC. It looks like the problem can be traced back to the use of R_ObjectTables (see R_ext/Callbacks.h) The problem is a bit difficult to reproduce because it does not appear on x64 and because the official R interface to this functionality, the

1 dimensional optimization with local minima
I am using numerical optimization to fit a 1 parameter model, in which the input parameter is bounded. I am currently using optimize(), however, the problem turns out to have local minima, and optimize does not always seem to find the global minimum. I could to write a wrapping function that tries multiple intervals or starting values, but I would prefer a package that has built-in methods to make
