Hi, I have a problem with a regression I try to run. I did an estimation of the market model with daily data. You can see to output below: /> summary(regression_resn) Time series regression with "ts" data: Start = -150, End = -26 Call: dynlm(formula = ror_resn ~ ror_spi_resn) Residuals: M

Re: [R] Problem sourcing file

Is the file just definitions of functions, or do you have some statements that are being executed? Could the error be coming from them? Just defining functions should work just fine. On Fri, May 25, 2012 at 10:08 AM, Marta Tolós wrote: > Hi all, > > > > I created a file to define some functio

Hello, Simple question that I am stuck on and can't seem to find an answer in the help files currently. I have a list which contains repeated ID's. I would like to have R count the number of ID's. For example: ID=c(1,1,1,1,2,2,2,2,3,3,3,3) as.data.frame(ID) Clearly, there are 3 groups. How w

Re: [R] Basic help

Hello, First of all, 'c' is a bad name for a variable, it's also the name of an R function. Think a, b, k, d, ... Now, try y <- m %o% x + k Hope this helps, Rui Barradas Em 24-05-2012, 2:07, Abhay Joshi

Re: [R] R does not recognise columns and rows as they are supposed to be

Is the file format documented? If not you can search for a possible format if you know the values at the start of the file. For one of your files, show the results of the following: file <- "your filename here" for(what in c("double", "integer")) { for(size in c(4, 8)) { for(end

Hi, First, please be sure to "reply-all" when following up so that the thread stays on the public list. The messages suggest that you might not have 'root' access when installing the packages, so the installation of the packages to the default location fails. You need to 'su' to root via the c

This will loop only as many times as the largest number of consecutive NA's but uses vectorization within the loop. As currently defined, it will loop forever if the first value is NA. a <- c(1, 2, 3, NA, NA, 6, 7, NA, NA, 10) f <- c(0.9, 1.1, 0.9, 1.1, 0.9, 1.1, 0.9, 1.1, 0.9, 1.1) a1 <- a alag

Re: [R] applying cbind (or any function) across all components in a list

This should give you what you want and it is simpler than the earlier version: a1<- array(1:6, dim=c(2,3)) a2<- array(7:12, dim=c(2,3)) l1<- list(a1,a2) a3<- array(1:4, dim=c(2,2)) a4<- array(5:8, dim=c(2,2)) l2<- list(a3,a4) pattern <- cbind(c(1, 2, 2, 3), c(1, 1, 2, 2)) lnew <- lapply(1:
