Hi, Somehow I forgot how to do this... Say I have a command that produced a 28 x 28 data matrix. How can I output the matrix into a txt file (rather than copy/paste the matrix)? Thanks...

Hi, Suppose I have a matrix with, say 12 columns. I would like to extract out column 2 ~ 8 and 11 ~ 12 then combine them together. I tried with success to extract out the columns by doing: foo <- test[,2:8] goo <- test[,11:12] However then I am having trouble combining foo and goo. Helps are appreciated! Cheers, Kevin ----------------------------------- Ko-Kang Kevin Wang

Hi, Suppose I have a dataset with 10 columns, let's call it "foo". Now if I want to extract out only column 2 ~ 8, then I know I can use either: foo[ ,2:8] or fooNew <- list( foo[ ,2:8] ) (Is there any other alternative, just out of curiosity?) But, if I only want, say, column 1, 4 and 7, I tried: fooNew <- list( x = foo[ ,1], y = foo[ ,4], z = foo[ , 7] )

Hi, Is there any difference in the gam() function in R and Splus? I just tried to do an Ace Plot (plotting the result of the gam() ) on a dataset. R gave me four (the data set has one response and four explanatory variables) ace plot with perfectly straight lines. I kind of felt that it is highly unlikely, so I tried it in Splus. Using the exact commands Splus gave me four completely

Hi, I'm just wonder if there is an R equivalent function of gam() - which exist in Splus. Also does anyone know if the library( modreg ), which comes with the installation file of R 1.3.0 (Windows version), exists in the previous versions of R (again, Windows version)? Or does one need to install the library into the previous versions of R explicitly? Thanks, Ko-Kang Wang

Hi there, Just out of curious, is there any difference between loess() and lowess() in R (and Splus in fact). Which one is more often used?

Hi there, I'm trying to get the manual for an R package (that I'm creating) to work... Firstly, I created the *.Rd files (by following the instructions in "Writing R Extensions" and using prompt() in R, then edit the *.Rd files. I then copy them into the "pkg/man" directory as suggested by the manual. However when I load the library (successfully) in R, I cannot

Hello, Can anyone offer any insight on graphing classification dendrograms with the nodes marked? plot(tree()) produces a nice tree structure but there's no acccompanying text. Thanks, D S.

Dear R-users, I am learning to use R 1.3.1 on a Pentium running Windows '98. I'm puzzled that several statistical procedures, t.test and chisq.test, do not appear to be available on R version 1.3.1. For example, if I type "t.test", I get the reply, "Object "t.test" not found". Is there a package that I have to load in order to have access to these

Hi, I was tutoring in the lab when a student asked me this question. Is it possible to save the work done in R, then source it back in AND display all the work within R later? I know that one can save the history (i.e. all the codes in a session) in *.R format, then source it back in at a later stage. However the historical codes will not be displayed within R, only the line source(...) is

Hello all, I've tried to reproduce the contour plot that appears in the book of Venables and Ripley, at page 255. Is a F-statistic surface and a confidence region for the regression parameters of a non-linear model. It uses the stormer data that are in the MASS package. I haven't been able to reproduce the plot either in R ( version 1.5 ) and S. It makes the axes and it puts the

Hi, I input this command on a data matrix: > apply( traffic, 2, function(z){z-mean(z)}) and got the following error messages: Error in sum(..., na.rm = na.rm) : invalid "mode" of argument Can anyone tell me what is wrong here?

Hello, I would like to apply BAGGING to classification tree. Does a package exists on that method? In advance I thank you for your answer and I am looking forward to hearing from you .

Hi there, I'm trying to write an R library (for Windows version) when I encountered this problem. I put in a dataset called mussels into a sub-folder, data (I saw this is how it is done in other libraries). However when I load the library in R and typed: data(mussels) it complains it cannot find the data set in the library. Everything else works fine (so far), am I missing something

Hi, I've been reading the Data Import and Export manual (page 25 on Connection chapter) but somehow I can't manage to get what I want. I have a 28x28 distance matrix, which I would like to export to a file. What I did was something like: zz <- file("ex.data", "w") # open an output file connection cat( traffic.manDist, file = zz ) # traffic.manDist is my

Hi, Can anyone tell me how I can compile R from source under Windows environemtn (I kind of know how to do it in a UNIX enviroment)? What I mean is, suppose I make some changes in the R base, or reorganising the libraries, and want to compile into a Setup.exe file (like the one located in CRAN), how should I do this? Many thanks in advance... Ko-Kang Wang

Hi, I am interested in seeing the LaTeX version of R manuals (such as An Introduction to R), and I found from CRAN that: "The texinfo sources of the latest version of these documents are contained in every R source distribution (in the subdirectory doc/manual of the extracted archive). " However when I went into that directory I only found the pdf and html version. Are there any

Hi, Suppose I've got a data set that I found the eigenvalues and eigenvectors. Then I want to draw a screeplot for the eigenvalues. However it returns: Error in matrix(w.m, nc = NC) : negative extents to matrix Then I tried a plot() function on the eigenvalues of the data set, and I can successfully draw it! And the output looks like what the screeplot would show to me. Is there any

Hi all. A friend of mine asked me to assist with an R presentation to the Penn State LUG in a few weeks. The audience will be predominately computer scientists and/or engineers (I suspect) and they are just looking for presentations of good open source software and my friend volunteered R. We are both relatively new to R, so I thought it would be best to ask the list for your opinion....what do
