Hi Folks, Apologies to anyone who'd prefer not to see this query on this list; but I'm asking because it is probably the forum where I'm most likely to get a good answer! I'm interested in the provenance of the name "normal distribution" (for what I'd really prefer to call the "Gaussian" distribution). According to Wikipedia, "The name "normal

Hi, i was wondering if there is a way to extract statistic calculated by the function bwplot in numeric format, i.e. a list with values of borders mean etc. Going through the help i couldn't find it, and text of the function itself(bwplot) is very long.

Hi, i'm trying to read some data from excel files but it seems that neither xlsReadWrite nor sqlFetch (RODBC) doesn't like the format (Excel 5.0). When i open the file in Excel and save it in a new format Excel 97 -2003 everything works fine. Is it possible to use ODBC connection to open old format files, or i guess i will have to open and save every file in Excel in new format, which

Hi to all members, i have a question about class inheritance and methods using R.oo package: I have the following code and it doesn't work, guess i'm doing smth wrong and there is nothing in the help. library(R.oo) setConstructorS3("ClassA", function(A=15) { extend(Object(), "ClassA", .size = A ); }) setMethodS3("print", "ClassA",

Hi, How can I specify a Cox proportional hazards model with a covariate which i believe its strength on survival changes/diminishes with time? The value of the covariate was only recorded once at the beginning of the study for each individual (e.g. at the diagnosis of the disease), so I do not have the time course data of the covariate for any given individual. For example, I want to state at the

Hi everyone, I am starting learn to call C code from within R. So far, I've been trying toy problems to see if I can get them to work. One of the things I'd like to do is pass an arbitrary R function to C, evaluate the value in the C code using eval, and then return it. I also want to allow an arbitrary number of arguments to the function using "...". The code for my toy

Hi, is there a R function that order a matrix according to some criteria based on the rows(or cols) of that matrix? For example, let's say that my matrix S is composed by n rows S_1, S_2,.., S_n and that I compute some real value g_i=g(S_i) for each row. Then I want to order this set of g_i (from smaller to bigger) and order the correspondent row to the new position. Is it possible (apart

Hi, i was wondering if there is a way to annotate rgl plot, after searching i haven't found anything suitable. I saw function text3d but was thinking more about text on the margin, so not interactive.

I learnt that functions can be handled as objects, the same way the variables are. So, the following is perfectly valid: > f = function(a, b) { + print(a) + print(b) + } > > f1 = function(foo) { + foo(1,2) + } > > f1(f) [1] 1 [1] 2 > I also know that operators are functions, so, I can call: > '+'(1,2) [1] 3 > However, when I want to pass the

Hi, I try to convert a string into date format. Please see the following two examples. When the time is midnight (i.e. 00:00:00), R can't convert it correctly and get a value of "NA". How to make it work and get the value of "2001-03-23 00:00:00"? Thanks!! =Example 1===================================== > S <- 20010323120000 > sTime <- strptime(paste(S),

Hi All, I am running a scatter plot and trying to add a best fit line. I use an abline function, but get no line drawn over the points. I also get no error. I arm using V 2.10.0 on Windows 7. Here is my code, including the SAS transport file import: require (foreign) require (chron) require (Hmisc) require (lattice) clin <- sasxport.get("y:\\temp\\subset.xpt") attach(clin)

Hi, I am having trouble using constrOptim. My target is to do a portfolio optimization and there some constraints have to be fulfilled. 1) The weight of each share of the portfolio has to be greater than 0 2) The sum of these weights has to be 1 I am able to fulfill either the first or the second constraint but not both. One simple way would be to fulfill the first constraint by using optim as

Hi, I'm using R to collect data for a number of exchanges through a socket connection and constantly running into memory problems even though task I believe is not that memory consuming. I guess there is a miscommunication between R and WinXP about freeing up memory. So this is the code: for (x in 1:length(exchanges.to.get)) { tickers<-sqlQuery(channel,paste("SELECT Symbol

Here is the patch for making syslinux enable opening partitions with fat filesystems (well, the architecture is in place to make it open other filesystems too). Usage is like this: #include <syslinux/io.h> #include <syslinux/partitions.h> #include <fs/fat/libfat.h> syslinux_devdesc dfd; struct libfat_filesystem* fs; diskinfo disk_info; char mbr[512]; static part_entry

No offense, Segher, but the output quality of this thing is awful. =) I'll disregard the fact that, at least with *my* compiler, the source tarball I downloaded reduces every packet to zero bytes, which isn't terribly interesting. I decided to set the byte reduction to something constant: I started by dividing each packet's size by 2 just to see what would happen. The resulting ogg

Forum, I am attempting to plot weekly horizontal histograms, something very similar to: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109 The part of the code used to create this graphic that interest me: # Draw the histograms for (i in 1:length(ages)){ par(new = TRUE) xmin <- -ages[i] + xlim[1] xmax <- xlim[2] - ages[i] ser <- freqs[, i+1] ser <-

Hi, I want to create variable names from within my code, but can't find any documentation for this. An example is probably the best way to illustrate. I am reading data in from a file, doing a bunch of stuff, and want to generate variables with my output. (I could make a "list of lists" and name all the elements, but I really want separate variables.) ################# #This is
