Dear R users, I want to aggregate data in the following way: ### X <- data.frame(u = c("T1","T1","T1","T2"), v=c("a","a","b","a")) X library(sqldf) sqlOut <- sqldf("select count(distinct(v)) from X group by u") sqlOut ### Now I want to get the same result without using SQL. How can I achieve that ?

Hi, I'm getting crazy: This does work: library(Matrix) a1<-b1<-c(1,2) c1<-rnorm(2) aDgt<-spMatrix(ncol=3,nrow=3,i=a1,j=b1,x=c1) png("myImage.png") image(aDgt) dev.off() But this doesn't !!! f<-function(x){ png("myImage.png") image(x) dev.off() } f(aDgt) My image is saved as a text file and contains nothing at all !!! Thanks in advance, Gildas Mazo

Dear R users, I'd like to build a simple design matrix in a efficient way. I naively wrote the code below. #### n = 15 k = 3 nbPerGrp = c(5,5,5) xT <- list() for (i in 1:k){ xT[[i]] <- rep(0, k) xT[[i]][i] <- 1 } X <- matrix(nrow = n, ncol = k) #design matrix for (i in 1:nbPerGrp[1]){ X[i,] <- xT[[1]] } for (i in 1:k-1){ for (j

Dear R users, Given a user-defined cumulative distribution function F, I want to compute F^{-1}(x). How is that possible with R? Best Regards, -- Gildas Mazo PhD student MISTIS team at INRIA Grenoble, France [[alternative HTML version deleted]]

Hello, I have a MANOVA model and I want to test the following hypothesis: LBM = 0 where B is the parameter estimates. Is there any function to do this in R? Cheers, Philippe -- Philippe Hup?

Hello All, Want very much to learn how to plot patient drug timelines. Trouble is I need to figure out how to do this today. So not much time for me to struggle with it. Hoping someone can just help me out a bit. Below are some sample data and code that produces what I think is the beginning of a very nice graph. Need to alter the code to: 1. Get the lines for the drugs to appear on the

Dear R users, I'm looking for tools to perform optimization subject to constraints, both linear and non-linear. I don't mind which algorithm may be used, my primary aim is to get something general and easy-to-use to study simples examples. Thanks for helping, Gildas

Dear R users, I'm using optim to optimize a pretty complicated function. This function takes the parameter vector "theta" and within its body I use instructions like sigma<-theta[a:b]; computations with sigma... out<-c() for (i in 1:d){ a<-theta[(3*d+i):c] out[i]<-evaluation of an expression involving 'a' (I use symbolic differentiation) } Unfortunately

Hi everybody. I'm just learning to use R. I've got a strange problem and I couldn't find any answer to my problem. So here am I. I want to visualize a model of regression on repeated measures : 5 measures (y) by x-value (lx for log10(x) ; lxf colonn is for as.factor) ; 5 x-values. I fail to use 'abline' command (regression's line don't display) in this particular

Hi, Can anyone tel me how to plot two boxplot at the same abscisse value ? Because I want to compare the discrimination of two different biological methods of the same data.

We're moving a somewhat complicated call center over to an Asterisk system, and I'm looking for documentation on queue/agent configuration. So far I haven't found anything on the Digium or Asterisk websites, and I was hoping that someone could point me in the right direction. Thanks, Devon

I've had success on "older" model Lenovos.....(T-410 / T-420 / T-430) but anything beyond those seems to have some issue or another. I was even able to swap the standard drive to an SD (250GB) on a T-430 and it's running g like a champ. A lot of the newer stuff is OK as long as you don't have any boutique drivers for video network or sound. YMMV. On Sep 29, 2016 9:18 PM, John

I''m having a strange issue with Mongrel. Post-install of Mac OS X 10.5, my Mongrel will not start under any circumstances. I''ve already removed ("sudo gem uninstall mongrel"), ran "gem cleanup" to remove old versions and then installed the latest gem version (1.1.2). When I run "mongrel_rails start" anywhere (inside a fresh Rails app, random place

Actually, it''s a bit more complicated than that... I have a div (we''ll call it the "portal") of a fixed size and absolute positioning, with an overflow: scroll set. Inside, I have a container div with relative positioning. This inner container has a series of absolutely-positioned elements which are draggable with a vertical constraint. The height of the container is

Hello everyone, I hope my question fits in this list. Anyway, on to the absolutely weird. I'm trying to access a Samba 2.0.7 Server with Share Level Security from a Win2K SP1 Box. Now, I've got one share named home pointing to /root. When I access that share from Win2K (SWAT and the logfile show that the access does happen as root, just as desired), the eth0 device somehow locks up. I
