I have built rsync on IA64 using Intel's 'icc' compiler and can run the rsync executable interactively but when attempting to run under 'crontab' I get the following error: + /home/horace/mccssmb2/src/rsync-2.6.9/rsync -z --partial -v --progress --recursive --stats --times --links --exclude-from=/project/horace/mcc101/.rsync-EXCLUDE --timeout=1200 /project/horace/mcc101

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

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 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,

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

Folks, I've entered into an R programming territory I'm not very familiar with, thus this probably very elementary question concerning the mechanic of a function call. I want to know from within a function the name of the variables I pass down. The function makes use of the "..." to allow for multiple unknown arguments, myfun = function(...) { do something } In the body I

Folks, I wonder if anything could be said about the distribution of a random variate x, where x = N(0,1)/N(0,1) Obviously x is pathological because it could be 0/0. If we exclude this point, so the set is {x/(0/0)}, does x have a well defined distribution? or does it exist a distribution that approximates x. (The case could be generalized of course to N(mu1, sigma1)/N(mu2, sigma2) and one

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

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

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

Folks, I'm making progress moving from Windows to Linux and have RKward up and running. I read somewhere that Rkward's supposed to be the Tinn-R for linux and Tinn-R has worked out great for me. So naturally I'd like to do the following, if possible, 1. How to ask Rkward not to load the last saved image. Right now whenever it starts, it loads an image from some obscure corner of my

This is not an R question but if anyone can help me, it's much appreciated. Suppose I have a series ( stationary ) y_t and a series x_t ( stationary )and x_t has variance sigma^2_x and epsilon is normal (0, sigma^2_epsilon ) and the two series have the relation y_t = Beta*x_t + epsilon My question is if there are particular values that sigma^2_x and sigma^2_epsilon have to take in

David & All, As you might have heard, Intel recently introduced a new low-power device called a Mobile Internet Device (MID). We're working in Intel's Open source Technology Center on the Linux Desktop UI. Given the small screen we're planning on using a stack-based window manager where each application runs full-screen (think Matchbox). We think it would be very cool to get a

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

Dear r list, I posted this on the S list last week since i'm using some of the FinMetrics functions on copula. Knowing there is a copula package in R, I figure this would be an appropriate forum to ask this question. I want to model inverse relationship between two (non-normal, non-symmetric) marginals with the gumbel copula, or with any copula. Say, x is lognormal and y is norm. Since
