Hi, everyone I wonder if there is a function in R with which I can create a square matrix with elements off main diagonal (for example one diagonal below the main diagonal). Thanks in advance! -- Jonas Malmros Stockholm University Stockholm...

Obviously, A cannot assign a row name because the dimensions do not agree. I can use rownames(vector) <- x$Name[1] though. then things get calculated (I saw it with browser()) but rbind does not do what I want it...

I wonder how one in R can fit a 3rd degree polynomial to some data? Say the data is: y <- c(15.51, 12.44, 31.5, 21.5, 17.89, 27.09, 15.02, 13.43, 18.18, 11...

Hello everyone. I use double for loops to fill in matrices, but there are surely better (and computationally faster) ways to perform that task. Could someone show me, given the following example of a double for loop, how this could...

Hello, I have a vector of names, say : names <- c("Factor 1", "Factor 2", Factor 3") I am creating a dataframe and I want the column names to be mixed like this: "Factor 1" " Sign Factor 1" "Factor 2" "Sign...

Thanks, Hans-Peter, But still, this is quite difficult to understand for non-initiated. What do expressions "exported variable" and "internal variable" mean? What is "name space"? In LAYMAN terms. Thanks in advance! On 10/29/07, Hans-Peter <gchappi...

Hello, My response variable seems to be distributed according to Student t with df=4. I have 320 observations and about 20 variables. I am wondering whether there is a way to fit glm with Student t for error distribution...

Hi everybody, I wonder if there is a built-in function similar to Matlab's "normfit" which computes 95% CI based on the normality assumption. So, I have a vector of values and I want to calculate 95% normal CI...

I have a data frame, where two last columns - "month" and "year" - are character vectors. The "year" vector is made of two numbers (i.e. "97" for 1997, "07" for 2007, etc) What I want to do is to create...

Dear list members, I create a pdf file with a number of barplots and histograms: pdf(file=my.pdf.file, paper="a4", width=6, height=10) ... dev.off() Then I run a model and plot fitted vs residuals and interactively...

Dear Charilaos, Thanks, I see what you mean, but I just simplified the real code here and I made a mistake by putting +2, it is +1. :-) JM On Dec 17, 2007 8:02 PM, Charilaos Skiadas <cskiadas at gmail...

Bill, Alberto, Gabor, Thank you for answering my question. Now I learned about outer() function. That was a straightforward example. But what if I had a matrix, where the last column was filled with values first (again, a for loop...

Dear Mr. Rowlingson, Rizopoulos, Jaworski, and Ripley Thank you for your help with the polynomial. Regards, Jonas On Jan 7, 2008 5:18 PM, Barry Rowlingson <b.rowlingson at lancaster.ac.uk> wrote: > Dimitris Rizopoulos wrote: > > try this: > > > > y <- c...

Dear R users, I have a huge database and I need to adjust it somewhat. Here is a very little cut out from database: CODE NAME DATE DATA1 4813 ADVANCED TELECOM 1987 0.013 3845 ADVANCED THERAPEUTIC SYS LTD 1987...

Hello, I am using textplot function in gplots package to put some model output inside a PDF file, but it does not seem to work properly with PDF. I am doing follwing: pdf(file="C:/...", paper="a4", width=8, height...

Dear list members, I have written a function, called say Analysis. I supply an Excel file name as an argument, it does analysis on this file and returns a pdf file with specific plots, and a text file with several...

Hello everyone, I am learning about copulas and also do some MATLAB/R coding to get better understanding of how copulas work. Recently I have started coding simple copula-GARCH models, that is I fit say AR(1)-GARCH(1...

I have a data frame named "database" with panel data, a little piece of which looks like this: Symbol Name Trial Factor1 Factor2 External 1 548140 A 1 -3.87 -0.32 0.01 2 547400 B 1 12.11...

Dear Gregory and members of R-Help I found what was causing the problem, it was the fact that my R Console window is minimized by me horizontally, and therefore summary output does not fit and gets split, and function...
