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

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

Hellos, I have date/times in 64-bit Julian format, that is the number of milliseconds since 1 jan 1970 (or something like that). E.g., "1159884877406" For the life of me I can't figure out how to render these in a more readable format, e.g., "2006-10-04 23:12:93.191" (and I have tried to do my best searching the archives and help etc ...) Thank you most

I have a time stamp in UTC (GMT) time: > format(ISOdatetime(1970,1,1,0,0,0)+1165398135729/1000,"%Y-%m-%d %H:%M:%OS3") "2006-12-06 09:42:18.823" (note millisecond accuracy, but not relevant to question here) Now, this time stamp actually "happened" at local (Swedish) time one hour later (10:42). Regarding summer/winter adjustments in time ("spring

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

Has anyone out there compiled R for the Umbutu Linux* (ne? Debian) v. 5.04 distribution for Intel-type platforms (32 and 64 bit) ?

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

Dear all, I cannot find a function which would allow drawing hist and density on the same graph. x <- seq(1,40,1) y <- 2*x+1+5*rnorm(length(x)) hist(y,freq = FALSE) plot(density(y)) thanks a lot for the help [[alternative HTML version deleted]]

Dear all, I compared tk_choose.files on linux with choose.files or tk_choose.files on windows and found that tk_choose.files does not allow multiple selection on linux - independent on keyword setting "multi". > tk_choose.files(default=paste(path.original,"",sep=""),caption="Select file(s)") On linux I get the error message: File <list of

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

An update: Running this block of code: # Load libraries library(tcltk) library(tidyverse) library(officer) filepath <- setwd(tk_choose.dir()) filename <- "Now they want us to charge our electric cars from litter bins.docx" #full_filename <- paste0(filepath, filename) full_filename <- paste(filepath, filename, sep="/") if (!file.exists(full_filename)) { ?

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 >

Hi Eric Thanks for that. That seems to fix one problem (the lack of a separator), but introduces a new one when I complete the function Calum proposed:Error in docx_summary() : argument "x" is missing, with no default The whole code so far looks like this: # Load libraries library(tcltk) library(tidyverse) library(officer) filepath <- setwd(tk_choose.dir()) filename <-

Dear Everybody! I want to export data to LaTeX.

Hello, How I can compute in R the orthogonal complement of one matrix? If A (n x m ) matrix of full column rank (n>m), its orthogonal complement is denoted by A_ . A_ is n X (n-m) matrix of full column rank and such that A'A_=0. I need to compute A_. How I can compute A_ in R? Best Regards, /Florin -- Florin G.

We use single queue even if multiqueue is enabled and let admin to enable it through ethtool later. This is used to avoid possible regression (small packet TCP stream transmission). But looks like an overkill since: - single queue user can disable multiqueue when launching qemu - brings extra troubles for the management since it needs extra admin tool in guest to enable multiqueue - multiqueue

Hi, I fail to find "choose.dir()" in my current R install (see below)? Didn't that exist at some point? How to achieve "file.choose()" equivalent functionality for directories?
