To all moderators i guess, my question was probably not clear this is not a homework, i am trying to understand R by doing some exercise in my book. I will however participate a course in R in august and thought it could be good to have some knowledge before. I hoped for help from you since i have no instructor to ask, that would have been my first choice. thanks anyway Lotta

1. Emma is performing an experiment that requires individual handling of some animals. The sizes of the animals are lognormally distributed: The natural logarithms of their sizes has a normal distribution with mean 3 and standard deviation 0.4. The time (in minutes) it takes to handle each animal is given by 10 + s · 1.5 + eε for animals with s ≤ 20 20 + s · 0.8 + eε for animals with s > 20

Windows-32 has a time structure called FILETIME, a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC). That is not a typo, the year is 1601. Does anyone have a clue(or algorhithm)for how this is converted to something a little more POSIX-like ? Thank you, Derek -- Derek N. Eder Gothenburg University VINKLA - Vigilance and Neurocognition

I want to migrate my R workspace databases (e.g., .Rdata) from Windows to Linux. The R help file for "save" says that "[a]ll R platforms use the XDR representation of binary objects in binary save-d files, and these are portable across all R platforms." Is it is simple as that? Copy the Windows .Rdata file to the Linux .ext3 file system? Thanks, Derek Derek N. Eder

I would like a function that return the X,Y position of the mouse cursor whenever it is called PERIOD, i.e., without the button presses of locator() or identify(). E.G., > where.is.mouse() [1] 123 34 # X and Y coordinates of present mouse position in current graphics window Is this a conceivable R function or does it need to be addressed with a call to the OS (Windows 2000 in my case)?

My question is so basic that I am (almost too) embarrassed to admit that I could not find an answer after an hour's worth of homework. What is the Trellis / Lattice analog for the axis(graphics) function that enables the creation of axes in locations other than the default (i.e., bottom for X axis and right for Y axis) ? For example when plotting mileage against weight (in American

I am having trouble understanding what must be a quite simple rule of scope. In the code example below, the argument to the main function, my.subset, would like to be passed to the function LME. This does not happen however. Curiously, the other argument (my.data) is passed to LME. This problem goes away with this: assign("my.subset", my.subset, env = sys.frame()). It works, but it

Isn't there a cryptic footnote somewhere in the blue book that describes regular expressions as "a funny little language ..." ? Well, I'm not laughing! I've googled and Man paged, but the GREP-style solution to the following problem still eludes me: ... Using a regular expression in the "pattern" argument to list.files() to restrict the return to filenames which

How is exact pattern matching achieved in GREP (and GREPlike) functions ? # Want: listing of all object names that end in *.lm > objects(pattern="*.lm",pos=1) # ... but get: all objects that partially match *.lm, e.g., *.lme [1] "j3.lm" "J3.lme" "j8.lm" "J8.lme" # Want: position of string "4jan2002" in vector >

Dear all, Does anyone knows why the results of a BIOENV (PRIMER v. 6.1.15) are diferent of the bioenv() + mantel() in vegan? Not the spearman correlation, indeed the pseudo-p value. I know that the approach bioenv() + mantel() is biased. So, how the BIOENV (PRIMER) ends with larger p values (permutated). Acctualy how the permutation test in BIOENV (PRIMER) is conducted. The user guide does not

sorry for cross-posting Dear all, I have tow (several) bivariate distributions with a known mean and variance-covariance structure (hence a known density function) that I would like to compare in order to get an intersect that tells me something about "how different" these distributions are (as t-statistics for univariate distributions). In order to visualize what I mean hear a little

Hey there, I'm an unhappy camper since I didn't carefully select my updates to install for Linux, now I'm stuck with the newest wine, which for some reason broke my company of heroes. There is no downgrading Wine on Ubuntu Karmic is there? I have not been able to find package archives so far. Before, I had 1.1.32, and COH worked perfectly. Now however, it (the game) searches for

Hi I am running Arch x64. I have installed Il2-1946which works perfectly. There are some mods I would like to add but cannot install. When I run 'wine setup.exe' for the mod installer I get the error messages below and a dialogue box telling me that I have the error I reference in the title field. All I've seen so far is that I should delete the installshield professional folder

I suspect that the recent queries about reading database files into R implicitely answered my question here, but I'll ask anyway. Are there any native binary file read routines in R? I need to a binary data file consisting of 2 byte records, strip off the upper 6 bits (using a logical AND, leaving a ten bit word), and then write the ten bit number in text form for R. Assuming that R
