Dear list, I know it must be obvious and I did my homework. (In fact I've RSiteSearched with keyword "remove AND library" but got timed out.(why?)....) How do I unload a library? I don't mean getting ride of it permanently but just to unload it for the time being. A related problem : I have some libraries loaded at startup in .First() which I have in .Rprofile. Now, I exited R

Folks, The projection pursuit regression function in the base R seems to crash when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be

Dear list, I know this is really basic question but I just couldn't get anything to work. (I did a R site search with keywords "zoo" and "data frame" but the server timed out on me.) I have a time series which has the following (typical) format, DATE Open High Low Close Volume 01-JAN-2006 5.25 5.25

Hi all, I have two questions. Can some one give some help? The first question is regarding the pair of operators "&" and "&&". What is the difference between the two? The second question is regarding "<-" and "=". Usually we use "<-" as the assignment operator. I saw some people use "=". Is there any

Hi list, I'm sure the explanation must be laughably simple to the experts out there, but I just could figure it out. I have a simple data frame that looks like, >head(da.off) DDate OffP 1 2005-01-01 41.23 2 2005-01-02 44.86 3 2005-01-03 44.86 4 2005-01-04 43.01 5 2005-01-05 45.47 6 2005-01-06 48.62 where the first column DDate currently is character, and OffP is numeric. I want

Hi folks, Is there a function to show the size of an R object? eg. in Kbytes? Couple months ago Bendix Carstensen posted this marvelous little function lls(), which shows all objects in the current workspace by mode, class and 'size'. This is a wonderful enhancement to the build-in ls() already and I now have it sourced in my Rprofile.site at startup. The only drawback is,

Following the official instructions to install R on ubuntu 10.04, I issued this command on the prompt, sudo apt-get install r-base Here is the error msg, Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that

Hi list, I'm trying to turn a date into something productive. (Not what you may be thinking....) I want three functions so I could take a "date" object and get the day of week, month, and year from it. xx <- as.Date("2006-01-05") month(xx) equal 1 day(xx) equal 5 year(xx) equal 2006 I'm aware of the weekdays() and months() functions in the base package. But

Trying to install Winzip 9 under Winetools 2.1.2 - keep getting "Zip file is damaged, truncated, or has been changed since it was created etc" so Winzip doesn't install - any suggestions please? Andy

Is anybody suffering from a similar problem or can anybody suggest a cure or a pointer......? I've various hardware platforms (both HP & Intel though all SMP) scattered around remote sites each running one of the following OSs (Redhat 7.2, Redhat 7.3, Mandrake 8.2 & Mandrake 9.0) each with Samba installed (either the version that ships with the relative OS or 2.2.5.2 or 2.2.8.2

Folks, i thought it should be straightforward but after a few hours poking around, I decided it's best to post my question on this list. I have a data frame consisting of a (large) number of date columns, which are read in from a csv file as character string. I want to convert them to Date type. Following is an example, where the first column is of integer type, while the rest are type

Dear list, First apologize that this is trivial and just betrays my slothfulness at the keyboard. I'm sick of having to type a long name just to get a glimpse of something. For example, if my data frame is named 'AuroraStochasticRunsJune1.df" and I want to see what the middle looks like, I have to type AuroraStochasticRunsJune1.df[ 400:500, ] And often I'm not even sure rows

This is a repost of a simple question about Windows Vista and R (with answer), along with a heads-up on other Windows Vista issues that people may not be aware of and that may impact R development. 1. The standard package install process fails because the user does not have permission to write to Program Files/R/R-version/library. Apparently the install process has already been modified to give

Hi folks, This is really minor but to someone not familiar with the various tentacles of the lmer package it could be really annoying. I was trying to plot the posterior density of the fixed effect parameters of a lmer model, > hr.mcmc = mcmcsamp(hr.lmer, n=50000) > densityplot(hr.mcmc, plot.points=F) There is this error, "Error in densityplot(hr.mcmc, plot.points = F) : no

Hi list,I apologize if you see funny fonts, b/c I'm using the new Windows Live Hotmail and don't know how to turn off the "rich text" mode.....I have successfully built and installed a R package in windowsXP for R-2.5.1. But when I tried to create a .zip file so I can use "Packages/install package(s) from local .zip files..." to install it, it seems R only recognizes

this was previously posted only on samba-ntdom, but that was probably not the right list so i'm cross-posting to both samba and samba-ntdom. here's the problem: on NT4 w/ SP4 or SP5, self-extracting 16-bit install files work just fine in directories w/ Long File Names. on SAMBA 2.0.5a, i can get none of the aforementioned files to install from directories w/ Long File Names. a good

I have installed WINE with apt-get wine command. But, when I run any windows software, I get this error : root@(none):/mnt/hdd_C/program files/winzip# wine winzip wine: creating configuration directory '/root/.wine'... err:advpack:create_tmp_ini_file Unable to create temp ini file err:advpack:create_tmp_ini_file Unable to create temp ini file Failed to open the service control manager.

Hi OK, final stretch now, thank you to everyone who has helped! (hopefully) final question - what does R CMD build actually do that tar/gzip and WinZip do not? I have successfully used R CMD build to create a .tar.gz version of my package, which installs well and works under Linux - hurray! I naively thought that all I had to do now was create a .zip version (using something like WinZip) and

Hej, Calling newuoa (from the minqa package) makes R crash when the package rgl is loaded first. This however only on certain selected data. The data used for testing (saved to 'bugs.R'): xvals = c(1,2,4,5,7,8,9,10,11,12,14,15,16,18,19,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36) yvals =

I am looking for a recommendation for an open source competitor to Winzip. I seem to recall Brian Ripley mentioning one in the last year or so, but couldn't find it in the mail archives. (Searching on Ripley there is somehow not terribly useful.) Suggestions?
