Is there an online archive of r-help that shows recent postings? The one I saw on CRAN posted monthly collections, the last one at the end of May. The reason I ask is that I want to re-read that thread on the arrow keys not working in the latest Windows release. I appear to have been bitten by the same bug, and can't remember if anyone found a solution. Duncan Murdoch

Hi, I think I found the problem. It lies in my Fortran program. Is there a way, after a DO loop, to make sure it does NOT return anything?

Hi there, I know this question may sounds strange, but here it goes: Is it possible to delay the speed of a for loop? For example, if I have: for (i in 1:100) { blah blah blah } within the for loop I want to draw a series of plots, and combining the plots together I'll have an animation. Problem is the loop is too fast and I only see the end result (which is not surprising actually).

Hi, Now suppose I have just one list called FOO, which has 25 objects, e.g.: [[1]] 1 2 3 4 5 [[2]] 6 7 8 9 10 . . . And I want to do something like: FRED <- data.frame(cbind(unlist(FOO[[1]]), unlist(FOO[[2]]), # ... for all 25 subsets )) Is it possible to do this, without doing unlist(FOO[[i]]) 25

Hi, I was trying to read in the following data set by using: gas <- read.table("gas.tab", header = T) when I got the error message: Error in "row.names<-.data.frame"(*tmp*, value = row.names) : duplicate row.names are not allowed Any help are appreciated. Thanks, Ko-Kang Wang

Hi, This is a simple question with if elseif....however I am having trouble constructing the solution for some reason. Suppose I have a data set with 3 variables, a, b and c say. Let's say c is the sum of a and b. So: a b c 1 2 3 2 3 5 3 4 7 . . . . . . . . . Suppose that I know there have been some data entry errors and I want to check if ALL values in c is

Hi, In the order() help file, there is an example like: a <- c(4, 3, 2, NA, 1) b <- c(4, NA, 2, 7, 1) z <- cbind(a, b) (o <- order(a, b)); z[o, ] How can I do something like "order a in ascending order, b in descending order"? And say I have a third vector c, and I'd like to add this to the previous condition "a ascending, b descending, c

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

Hi, Is it possible to create a ts() object, whose data is daily based BUT measured only on working days? In other words, suppose I have a data set with 255 observations, measured from 29 June 1959 to 30 June 1960. How would I create such a data? I tried something like: ts(c(...), start(1959, 180)) but I'm not sure what to use for frequency. In other words I don't know how to

I just installed the R-patched 1.4.0 and for some reason I now have trouble compiling R packages - I could compile it a few weeks ago with R 1.4.0 released in December. This only happens if I put the --binary option in. For example: Rcmd build --binary cw returns the error: make: Entering directory `/cygdrive/c/PROGRA~1/R/RW1040/src/gnuwin32' make DLLNM= \ -C C:/MyRWork/cw PKG=cw

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

Hi, I'm not sure if this can be done but.. I know that with ifelse() I can do something like: ifelse(x <= 3, 1, 2) to go through each element in my vector x, and if x_i <= 3 substitute the number with 1 else with 2. Essentially I'll get a vector with 2 levels. Can I tweak it so I can get 3-levels? For example: if(x <= 3) then 1 elseif(3 < x <= 4) then 2

Hi, Can anyone tell me what might cause this error message? Error in .Fortran("swallocate", as.double(mtx), as.double(wt), as.integer(n), : C/Fortran function name not in load table This occurs when I copied the Splus stepwise() function into R. I can source into R fine, but when I need to call that function on some dataset, I got the above error message. Platform

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, 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, I've been looking through the documentation for sample(), but can only get it to work with vectors. Is it possible to sample from a dataframe? -- Cheers, Kevin ------------------------------------------------------------------------------ /* Time is the greatest teacher, unfortunately it kills its students */ -- Ko-Kang Kevin Wang Master of Science (MSc) Student SLC Tutor and Lab

Hi, This is a very trivial question, and I do not know why I cannot remember the answer at all! How does one get the entire system information (which OS, R version....etc) using an R command?

Hi, Suppose I have a categorical variable called STREET, and I have 30 levels for it (i.e. 30 different streets). I want to find all those streets with only 15 observations or below then collapse them into a level called OTHER. Is there a quick way, other than using a for() loop, to do it? Currently what I'm doing is something like: ### Collapse STREET (those < 15) st <- c()

Hi, Is it possible to add a subtitle that appears directly below the main title? I tried the "sub" parameter, but it adds sub-title to the bottom of the plot.
