Hi all, This is my first post to the developers list. As I understand it, aggregate() currently repeats a function across cells in a dataframe but is only able to handle functions with single value returns. Aggregate() also lacks the ability to retain the names given to the returned value. I've created an agg() function (pasted below) that is apparently backwards compatible (i.e.

The aggregate function does "almost" all that I need to summarize a datasets, except that I can't specify exclusion of NAs without a little bit of hassle. > set.seed(143) > m <- data.frame(A=sample(LETTERS[1:5], 20, T), B=sample(LETTERS[1:10], 20, T), C=sample(c(NA, 1:4), 20, T), D=sample(c(NA,1:4), 20, T)) > m A B C D 1 E I 1 NA 2 A C NA NA 3 D I NA 3 4 C I

The config file indicates that if mail_location is empty, dovecot will try to find the mailboxes automatically (and by implication determine if the user is using mbox or Maildir format). But if the mbox inbox is non-standard (I have procmail delivering to ~/.mail) then one needs to specify mail_location = mbox:~/mail:INBOX=~/.mail and presumably dovecot will no longer try to determine what

I'm running rc31 and I've come across a weird little error in creating subfolders that's only apparent in a specific situation. I recently moved our entire campus from UW to dovecot, and as part of that migration, and following the wiki, I have some namespaces: ##default namespace namespace private { separator = / prefix = inbox = yes } #for

Dear addresses, I need perform a batch of 10 000 simulations for each of 4 options considered. (The idea is to obtain the parameter estimates in a heteroskedastic linear regression model - with additive or mixed heteroskedasticity - via the Kenward-Roger small-sample adjusted covariance matrix of disturbances). For this purpose I wrote an R program which would capture all possible options (true

I am using dovecot 1.0.rc15 (a similar problem occurred in rc10) on Solaris 9 (sparc). When working with a user who's home dir is on a local disk everything seems fine. But when that home is on an NFS-mounted disk things are very badly awry. Both the indices and the subscriptions file are being destroyed and what is left behind are files with names of the form .nfs72C034 etc. These files are

There's a little source code (typo?) bug in "samba-2.0.4/source/lib/system.c" that hurts compilation at least on HPUX 9.0x (with HP's cc, not gcc!) !! In HPUX's "/usr/include/sys/time.h": .. # ifndef _STRUCT_TIMEVAL # define _STRUCT_TIMEVAL /* Structure returned by gettimeofday(2) system call and others */ struct timeval { unsigned long tv_sec;

Hello everyone, I'm trying to estimate the parameters of the returns series attached using the GARCH code below, but I get the following error message: Error in solve.default(Hessian) : system is computationally singular: reciprocal condition number = 0 Error in diag(solve(Hessian)) : error in evaluating the argument 'x' in selecting a method for function 'diag' Can

I am attempting to lower the selectCC instruction to the instruction set of the backend I'm working on and I cannot seem to find a way to correctly implement this instruction. I know how this instruction should get implemented; I just have yet to find a way to do it. I want the select_cc instruction to be lowered into a comparison followed by a conditional move. I've attempted to use a

My question is about the "Signif. codes" , the output when I run matcoef =cbind(fit$par, se.coef,tval,2*(1-pnorm(abs(tval)))) dimnames(matcoef)=list(names(tval),c("Estimate","Std.Error","t value","pr(>|t|)")) cat("\nCoefficient(s):\n") printCoefmat(matcoef, digits=4, signif.stars = TRUE) Coefficient(s): Estimate

Hi, pretty good job you are doing with Samba... I have just downloaded Samba 2.0.4 and I have a problem trying to compile it. I have configured the "configure" file and ran it (./configure). When I type make, I can see all the different modules compiling but I have an error with the /source/lib/system.c file. It is concerning the timeval struct (which I concluded must be a system

Hello all, I'm trying to create a heatmap using 2 matrices I have: z and v. Both matrices represent different correlations for the same independent variables. The problem I have is that I wish to have the values from matrix z to be represented by color intensity while having the values from matrix v to be represented by circle size. I currently have the following in front of me and an unsure

If you found my subject heading to be confusing then I'm sure you'll enjoy the example I've included below. I find the apply type functions to be wonderful for avoiding loops but when I use them with existing functions, I end up using loops anyway to extract the vectors I want. I would appreciate it if someone could show me how to avoid these loops. Thanks. EXAMPLE:

Hi, While exploring how summary.lm generated its output I came across a section that left me puzzled. at around line 57 R <- chol2inv(Qr$qr[p1, p1, drop = FALSE]) se <- sqrt(diag(R) * resvar) I'm hoping somebody could explain the logic of these to steps or alternatively point me in the direction of a text that will explain these steps. In particular I'm puzzled

Hi! On my FreeBSD 12.0-RELEASE-p7 server I was unable to retrieve the correct information from my two UPS. Every time only the first UPS will returned when I entering "upsc apc900" or "upsc apc901". I don't know why (Bug or configuration issue on my side?!). I have downloaded the latest source code and with my "patch" I was able to get the right information

Hello, I am having some trouble setting up a bootstrapping prodecure. I create artificial data and would like to use these to bootstrap a t-test statistic from these. Especially I do not really get how boot uses the indices variable or i variable. Can anybody help out? Thanks!! b0 <- 1/2 # intercept as given b1 <- 1 # slope as given n

I define the following function to convert a t-value with degrees of freedom DF to another t-value with different degrees of freedom fullDF: tConvert <- function(tval, DF, fullDF) ifelse(DF>=1, qt(pt(tval, DF), fullDF), 0) It works as expected with the following case: > tConvert(c(2,3), c(10,12), 12) [1] 1.961905 3.000000 However, it gives me warning for the example below although the

Greetings, I have written a patch for rsync-2.6.1pre-2 which adds a --time-limit=T option. When this option is used rsync will stop after T minutes and exit. I think this option is useful when rsyncing a large amount of data during the night (non-busy hours), and then stopping when it is time for people to start using the network, during the day (busy hours). If this patch is accepted it may
