Dear all, There is this delcol() function in Splus. It is a support function for drop1.lm(). But it seems it disappears from R. Could some one tell me whether there is any equivalent function of delcol() in R or is there any other way that I can implement its functionality? Your help is highly appreciated!!! Regards, -Ji

hi chaps: a simple suggestion: R tells me who the contributors() are, but this should also tell me where I should mail suggestions to. Is it this mailing list? a repository of suggestions? an individual? this came up because i wanted to suggest two small enhancements: the first is for the summary() method for plain data frames. it would seem to me that the number of "NA"s

I asked the maintainer and he indicated that it might be a dll problem. Has anyone see this problem? I had installed the latest copy of tkrplot. I was trying to use teachingDemos when I first got the error. On 1/18/07, Luke Tierney <luke@stat.uiowa.edu> wrote: > Looks like tcl can't find the dll or something along those lines.

Hello Folks. This must be a silly question with a (not) obvious (to me) answer. Consider this: tmp <- matrix(1:200, nrow = 20) vec <- 300:309 tmp[9,] <- vec # replacing one row works fine p <- c(3, 11, 17) tmp[p,] <- vec # replacing multple rows pastes the values down a column and recycles vec. What I want to do is replace multiple rows simultaneously at once. I suppose I can

Dear All, I am using lars package written by Dr. Trevor Hastie, the version is lars_0.9-5 downloaded from cran. When I ran the diabetes example data attached in package, I found that the beta outputs from different machines are different. The difference is only about 10^-11 to 10^-12, some friends suggested that it possibly is a machine precision problem. But I check the machine numerical

Hi All... I haven?t found mention of this error anywhere. I'm trying to draw spline curves using grid graphics. Most of the time, I have no problems, but I have some data sets that give the error in the subject line. I'm not sure which end points are identical, but the end points passed to the function are definitely not identical. Any assistance appreciated! Bryan tst <-

Hello Everyone. I?m on a Mac, using rgl. Thanks to all the developers and maintainers on it! If I drag the mouse, I can rotate the view, if I hold down the option key or the ctrl key and drag, I get scaling (though at times I seem to alter the perspective?). Adding the shift key doesn't seem to modify anything. So, what I can't find is a key combination that translates the object.

Hello Again Gurus and Lurkers: I?m trying to build a very user-friendly function which does aov without having the user type in a formula (which would be tedious in this case). The idea is to take the response from a PCA score matrix, and the factors from a list. A simple example is the function given below, along with test data and a sample call to the function. I'm certainly having

I?m trying to build a simple formula interface to work with a function using ggplot2. The following scheme ?works? up until the plot(p) request, at which point there are complaints about xlim?s and a blank graphics window. Looking at str(p) I do see the limits are NULL, plus layer 1 claims to have an empty data frame (but df is reproduced correctly). I'm sure I'm missing something really

Hello All. I must be missing the really obvious here: mm <- function(d, i) median(d[i]) b1 <- boot(gravity$g, mm, R = 1000) b1 b2 <- boot(gravity$g, mm, R = 1000, strata = gravity$series) b2 Both b1 and b2 seem to have done (almost) the same thing, but it looks like the strata argument in b2 has been ignored. However, str(b1) vs str(b2) does show that the strata have been noted

Oh Knowledgeable Ones: I'm working on a project using grid graphics (for the first time). A toy example is given below, run it simply with >foobar() I am wondering why the pink dot and concentric circles are not centered on the 3-color axis system. Further, I feel like the concentric circles don't have the intended radius - if my math is right, the outmost circle should touch the

Hello Again R Folk: I have found items about this in the archives, but I?m still not getting it right. I want to use ggplot2 with facet_grid inside a function with user specified variables, for instance: p <- ggplot(data, aes_string(x = fac1, y = res)) + facet_grid(. ~ fac2) Where data, fac1, fac2 and res are arguments to the function. I have tried p <- ggplot(data,

Hello everyone, I have a dataframe with 1 column and I'd like to replace that column with a moving average. Example: > library('zoo') > mydat <- seq_len(10) > mydat [1] 1 2 3 4 5 6 7 8 9 10 > df <- data.frame("V1" = mydat) > df V1 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 > df[df$V1 <- rollapply(df$V1, 3, mean)]

Hello Again... I?m making a faceted plot of a response on two categorical variables using ggplot2 and having troubles with the coloring. Here is a sample that produces the desired plot: compareCats <- function(data, res, fac1, fac2, colors) { require(ggplot2) p <- ggplot(data, aes(fac1, res)) + facet_grid(. ~ fac2) jit <- position_jitter(width = 0.1) p <- p +

I'm not sure if this is the right target to which to direct this post, but I couldn't think of anything more appropriate. I just downloaded the Hmisc package to the Imac that I use.

Hello I'm trying to run a fortran code which use LAPACK subroutines. I think I should use some points shown in the manual 5.5 Creating shared objects but it is too technical for me :-(... Could anyone help me for the procedure to do: -which part of the manual is relevant for this type of question? actually I'm speaking from writing R extensions, should I read R admin? -point 1.2
