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 >

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

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

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)?

R. 1.1.0 The example below is self explanatory. ## 1 ## # works fine > binom.test((50*.64),50,.5,alt='g') ... Exact binomial test ... ## 2 ## # WHAT ! ? > binom.test((50*.65),50,.5,alt='g') Error in binom.test((50 * 0.65), 50, 0.5, alt = "g") : x must be an

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

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

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

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

I am used to using the [R] function choose.files() for interactive file selection in MS-Windows. What is the comparable function in Linux? I expected the function file.choose() to display similar behavior, i.e., a graphical interface diplaying a file listing, but all I seem to get is a "text input prompt". This does not seem correct. > file.choose() Enter file

Hi! I have Samba 2.0.0 running on a SPARC Solaris 2.6 box with a minimal smb.conf. I have enabled WINS support and this works as well. Everything works fine except for one NT box. Test 8 in Diagnosis.txt fails with: System error 5 has occurred. Access denied. The NT box is setup as a server, though only used as an ftp-server. Samba recognizes the NT server. Being a Unix guy myself, I

Hi, everyone! Can someone tell me why after configuring our Win95 clients as Samba clients (using tcp/ip and Microsoft Network) all browsers as well as ftp complain that there is no socket connection or that wsock32.dll is not available? Samba as well as email works fine and I did not have this problem with Win98 clients. The clients I am talking about use older versions of Win95. Earlier

We are using WINBIND that seem to get users from the domain correctly.Every time that I create a password through the smbpasswd for an user using smbpasswd -a USER, the password is created in the file but when I give smbclient / /linux/share USE%Pass I receive msg saying that there was logon mistake in the NT. If I try to use an user of the domain that I don't still include below in the

Hi, I have some trouble with the result of a fortran function calling the R binomial RNG: The C function rbinom is wrapped as in the file attached. My main fortran program starts as call rndstart() and ends as call rndend() I happen to call the binomial RNG within a loop as b = ggrbinom(1.d0,0.5d0) write(*,*) 'b=',b In certain cases, after a few iterations in the loop, b get

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

Dear Everybody! I want to export data to LaTeX.

Hi! I would like to do Cox regression using the available routines in the survival package BUT I want to use an arbitrary link function, i.e. want to use the model h(t)=h_0(t)r(beta'z) with arbitrary function r, instead of h(t)=h_0(t)exp(beta'z) Grateful for any comment on this, Dragi ----------------------------------------------------------- Dragi Anevski, PhD Mathematical

This is a question about the use of the Cox proportional hazards model to analyze event histories. I am looking at the responses of sympathetic nervous system activity to a stimulus. The activity I observe is a burst that can only occur once per heart beat cycle (e.g., a binary count). Typically bursts occur in 60-80% of the heart cycles * sensory stimuli can modify these burst probabilities.
