similar to: R-0.63.3 is released

I've rolled up R-2.8.1.tar.gz a short while ago. This is a maintenance release and fixes a number of mostly minor bugs and platform issues. See the full list of changes below. You can get it (in a short while) from http://cran.r-project.org/src/base/R-2/R-2.8.1.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course.

If I execute R CMD Rd2dvi foo.Rd I get messages of the form: Converting Rd files to LaTeX ... foo.Rd Creating dvi output from LaTeX ... Saving output to 'foo.dvi' ... cp: .Rd2dvi4366/Rd2.dvi: No such file or directory Done xdvi-xaw: Fatal error: foo.dvi: No such file. Indeed if I add the --no-clean flag and then cd to the .Rd2dvi<whatever> directory, I find that there is no

Hi, I've written some C code for density evaluation of the non-central t distribution. It works with the R-1.7.1 source code if placed in the src/nmath directory and after appropriate changes are made to Makefiles, to the dt function in src/library/base/R/distn.R etc. I haven't read a lot of R source code so it may need some R-ification, but I've tried to use the dt.c file as a

help(qt) states that: "ncp non-centrality parameter delta; currently except for rt(), only for abs(ncp) <= 37.62" so I would expect that calling qt with non-centrality parameter exceeding 37.62 should fail, instead e.g. calling > mapply(function(x) qt(p = 0.9, df = 55, ncp = x),35:45) gives: [1] 40.21448 41.35293 42.49164 43.68862 44.82945 45.97048 47.11170 48.25310 [9]

The function 'pchisq' from the 'stats' library gives a wrong result if the argument equals exactly zero: # Upper tail of central 1-df chi^2 distribution > pchisq(1 , 1, ncp=0, lower.tail = F, log.p = FALSE) [1] 0.3173105 > pchisq(0.5 , 1, ncp=0, lower.tail = F, log.p = FALSE) [1] 0.4795001 > pchisq(0.01 , 1, ncp=0, lower.tail = F, log.p = FALSE) [1]

Buenos días; Aunque ya llevo un tiempo con LaTeX y R no he conseguido que me funcione la librería tikzdevice. El primer problema está con tikzDictionary que me da como error: cannot create lock file. He estado buscando información en Google pero sin éxito. No he conseguido solucionarlo indicando un archivo en RProfile con options(tikzMetricsDictionary = ''path/archivo''). Cuando

Hi Folks, I note that, while the "chisq" functions dchisq(x, df, ncp=0, log = FALSE) pchisq(q, df, ncp=0, lower.tail = TRUE, log.p = FALSE) qchisq(p, df, ncp=0, lower.tail = TRUE, log.p = FALSE) rchisq(n, df, ncp=0) all have a slot for the non-centrality parameter "ncp", of the functions for the t and F distributions: dt(x, df, log = FALSE)

Dear List: The square of the noncentral t-statistic with noncentrality parameter \delta is a noncentral F with noncentrality parameter \lambda=\delta^2. So, t^2_{\nu,\delta} = F_{1,\nu,\lambda=\delta^2}. Consequently, it should follow that t^2_{1-\alpha/2,\nu,\delta} = f_{1-alpha,1,\vu,\lambda=\delta^2}. However, this is not what is happening with the following code. The central

I am writing a hp ilo module to automatically assign a static ip that is derived from the IP of the system which is fed in via facter. I basically just need to change the network the ilo is connected to. The ruby code works great inside the irb console. However, puppet doesn''t seem to be able to use the variable I have derived from the ipaddress. This is my first template so I am not

Hi Folks, I'm looking for a neat procedure for the following: Given t0 such that pt(t0,df,ncp=0) = alpha (given) find ncp0 such that for given beta pt(t0,df,ncp=ncp0) = (1 - beta) (In other words, what's the ncp such that you get power (1-beta) to detect it, using a 1-sided test with size alpha when ncp = 0?) In the past I've done the groping by hand, but this time it needs

Bug Description: Problem with the function pf() when the non-centrality parameter is large. Here is a sample command.

Full_Name: David Clayton Version: 1.8.1 OS: Linux Submission from: (NULL) (131.111.126.242) qchisq behaves very strangely when ncp is passed as zero (forcing internal qnchisq to be called) when first argument is small.
