Dear Friends. I found a puzzling phenomenon in R when you use 'if' within a function: # defining a function aaa aaa=function(a) {if (a==1) {aaa=1}; if (a!=1) {aaa=2} } # using the function: > b=20 > bbb=aaa(b) > bbb [1] 2 > typeof(bbb) [1] "double" > > > c=1 > ccc=aaa(c) > ccc NULL > typeof(ccc) [1] "NULL" It seems that only the last

_______________________________________________________________________________________ Hi, I was just wondering if there was any available R code that could handle general constrained optimisation problems. At the moment I'm using nlminb and optim, both of which allow box constraints on the parameters, but ideally I'd like to be able to specify more general constraints on the solution

_______________________________________________________________________________________ Hi, I'm writing up the online help for a package I'm developing (in-house only, sorry), and I've come across an odd glitch when trying to nest a list inside the "arguments" section of the .Rd file. I was just wondering if anyone could provide some insights. I'm using R 2.2.0 on

I am seeing an issue with getting certain sip devices to be recognized as defined SIP clients host= in the sip.conf and the only deference that I can find btw sources that work and don't work is that devices that send packets with an Initial Via header of themselves appears to work and pick the context correctly but those that don't have the Via just get dropped in the context of the

After a lot of processing I get a matrix into M. I expected each row and column to be a vector. But it is a list. R-Inferno says... "Arrays (including matrices) can be subscripted with a matrix of positive numbers. The subscripting matrix has as many columns as there are dimensions in the array—so two columns for a matrix. The result is a vector (not an array) containing the selected

Hello, I would like to plot the following xyplot : for each date of fff (1 date per panel), bbb=f(aaa) for the two groups (ddd=1 and ddd=2) superimposed. I can do it by group (see below) but not together. I looked at http://lmdvr.r-forge.r-project.org/figures/figures.html but I haven't found what I was looking for (to be honest, I haven't understood all the examples). Any help will be

Hi, I would really like to have a way to split long string literals across multiple lines in R. Currently, if a string literal spans multiple lines, there is no way to inhibit the introduction of newline characters: > "aaa + bbb" [1] "aaa\nbbb" If a line ends with a backslash, it is just ignored: > "aaa\ + bbb" [1] "aaa\nbbb" We could use

Hi there! I have been setuped exim and dovecot. Exim uses dovecot-lda to deliver mails to mailbox. Some configurations of exim: dovecot_virtual_delivery: ? driver = pipe ? command = /usr/libexec/dovecot/dovecot-lda -d $local_part@$domain -f $sender_address ? message_prefix = ? message_suffix = ? delivery_date_add ? envelope_to_add ? return_path_add ? log_output ? user = vmail ? group = vmail ?

Dear R-help, Here's a simple example of nonlinear curve fitting where nls seems to get the answer wrong on a very simple exponential fit (my R version 2.7.2). Look at this code below for a very basic curve fit using nls to fit to (a) a logarithmic and (b) an exponential curve. I did the fits using self-start functions and I compared the results with a more simple fit using a straight lm()

Suppose, 'fr' is data.frame with columns 'Y', 'A' and 'B'. 'A' has levels 'Aa' 'Ab' and 'Ac', and 'B' has levels 'Ba', 'Bb', 'Bc' and 'Bd'. 'Y' columns are numbers. I tried the following three sets of commands. I understand that A*B is equivalent to A+B+A:B. However, A:B in A+B+A:B is

Dear R helpers, Suppose I have following data.frame. df <- data.frame(category = c("treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_B", "treat_B", "treat_B", "treat_B", "treat_B", "treat_B",

I don't think it is reasonable to change the parser this way. This is currently valid R code: a <- "foo" "bar" and with the new syntax, it is also valid, but with a different meaning. Or you can even consider a <- "foo" bar %>% func() %>% print() etc. I like the idea of string literals, but the C/C++ way clearly does not work. The Python/Julia way

I have a to a samba server (4.4.16) on built on Solaris 11 samba pkg. It is a member of an Active directory domain. Users, for some time, have been experiencing long (20 -40 second) delays when browsing to, opening and writing a network share on the server. Attempts to do any of those results in a dialogue box being displayed showing: Contacting server: \\<server-name> \share

I have a samba server at ip address aaa.bbb.ccc.ddd I can connect to it from clients on subnets aaa.bbb.eee. and aaa.bbb.fff. I can't connect to it from clients on ggg.hhh. smb.conf has hosts deny = all hosts allow = localhost, aaa.bbb., ggg.hhh. The client can successfully 'ping mysambaserver' (resolves to aaa.bbb.ccc.ddd). Doing 'net view \\mysambaserver' fails with

Dear R helpers, Thanks a lot for your earlier guidance esp. Mr Davind Winsemius Sir. However, there seems to be mis-communication from my end corresponding to my requirement. As I had mentioned in my earlier mail, I am dealing with a very large database of borrowers and I had given a part of it in my earlier mail as given below. For a given rating say "A", I needed to have the bad-wise

hi, i have a simple code like below, in wich variable "aaa" does not alias to "bbb". i use TBAA to specify this, please see the code. then i ran this code thru LLVM optimization, and i expected that the second "store" instruction is eliminated. however, i am wrong: the second "store" instruction is still there after optimization. perhaps my TBAA setup is

Dear all, How could I use variables in a loop that their names are in a vector? For example: aaa <- 1:10 bbb <- aaa*2 ccc <- aaa+bbb varn <- c("aaa", "bbb", "ccc") m <- rep(NA, 3) for (i in 1:length(varn)) m[i] <- mean(varn[i]) # wrong thanks in advance Juli -- "Wars do not solve problems, wars generate even more problems"
