Hi friends, I would like to construct a matrix of seasonal dummies with number of rows (observations)=100. such matrix is written as follows:[1 0 0 0;0 1 0 0;0 0 1 0;0 0 0 1;1 0 0 0;0 1 0 0;0 0 1 0;0 0 0 1;etc...] . I wrote the following program: T=100 br=matrix(0,T,4) { for (i in 1:T) for (j in 1:4) if i==j br[i,j]=1 if else (abs(i-j)%%4==0 br[i,j]=1 else br[i,j]=0 } z<-br z but

Hi all. As the subject has come up. Powerware ups may contain several cpu's and different firmware versions.

I got dragged away from Asterisk (somebody made me an offer I couldn't refuse for system administration), but I'm thinking about seeing if I can't get it deployed at my new employer.

Has anyone made it so it can be first or last? - Jump to voicemail; you used to have to actually dial the

Hi all, I'm trying to get the value of y when x=203 by using the intersect of three curves. The horizontal curve does not meet with the other two. How can I rectify the code below? Thanks Muhammad ts <- 1:10 dd <- 10:1 ts <- seq(200,209,1) dd <- c(NA,NA,NA,NA,1.87,1.83,1.86,NA,1.95,1.96) plot(ts,dd,ylim=c(1.5,2)) abline(lm(dd~ts),col="blue",lty=2)

Subject says it all. Looking in /usr/include/gnu, I find stubs-64.h and stubs.h, but no stubs-32.h. This is probably related to my machine running a 64-bit install of Ubuntu. I'm not sure whether this should be rectified in Ubuntu or LLVM. Regards, Jo

Hello, Ever since I updated my CentOS 6 machine from 6.9 to 6.10 Xorg will not start with the 2.6.32-754 kernels. Instead the computer will reboot. This issue does not exist with the 2.6.32-696.30.1 kernel from CentOS 6.9 that I still have on my system. Has anyone else encountered this issue, and if so, how did you rectify it? Thank you for any help. Brian Bernard

Hi, my vector V<- c(1,0.5,0.06,0.056,0.01,0.04,0.4,0.9,0.82,0.1) if( V > 0.5) { V <- 1 - V } I get a warning saying only the first element will be used in comparing (if V > 0.5). However, my results tell me vis-versa ,it actually compares every element of the vector V with 0.5 and that is waht i want it to do. Using a for loop is expensive and time consuming since my actual

Hi - I can access R from Tinn-R by going to Options->Main->Application/R and setting the search path, but each time I exit Tinn-R I have to redefine the search path. Is there no way of fixing that directory as default?
