Dear all, I have problems to compile a DLL for Windows XP with R version 2.5.1 (2007-06-27). See output below: C:\AZ_DATEN\C, C++\BE_speedup>R CMD SHLIB dmypow.c Goto undefined subroutine &DynaLoader::bootstrap_inherit at C:\Programme\R\R-2.5 .1\share\perl/XSLoader.pm line 80.

Dear all, I would like to inquire, if it is a desired feature that the combination with rbind() of two data frames with factors columns does not sort the factors levels of the combined data frame. > str(rbind(data.frame(a = factor(c(4, 3))), data.frame(a = factor(c(2, 1))))) 'data.frame': 4 obs. of 1 variable: $ a: Factor w/ 4 levels

Dear all, on my Windows XP R 2.4.0 version with Package its version 1.1.4 I have a problem with str() applied on an its-object after a simple matrix manipulation on the its object (see below). I am not sure, whether this a problem with my application, its or str(). Of course, one can make > str(core(its(mat)) / 1) num [1:2, 1:3] 1 2 3 4 5 6 - attr(*, "dimnames")=List of 2 ..$

Dear all, according to the Help-page of DateTimeClasses {base} I should be able to do time - z with time date-time objects z a numeric vector (in seconds) or an object of class "difftime". However, on R version 2.6.0 (Windows XP) I get > Sys.time() - as.difftime(c("0:3:20", "11:23:15")) Time differences in mins [1] 1191837998 1191837318

Dear all, I am encountering a problem with lattice in the current version 0.14-13 with R version 2.4.0 on a Windows XP system. For example, histogram(~voice.part, singer) is not labeling the x labels according to the factor levels of voice.part, which it should do (and has done in former versions of lattice, as far as I remember). In addition, I get the warnings Warning messages: 1:

Dear all, I have an error message, when I try to convert a zoo object (called test) to ts (on R 2.4.0, Package zoo version 1.2-1, Windows XP) > test 1994-05-10 1994-06-09 1994-07-09 0.0024943889 0.0024881824 0.0006955831 > str(test) atomic [1:3] 0.002494 0.002488 0.000696 - attr(*, "index")=Class 'Date' num [1:3] 8895 8925 8955 > is.regular(test) [1] TRUE

Using Tinn-R (in windows) is possible to run latex and R from the same editor, which was great. Now, I am using Ubuntu-linux, which has been better than WinXP. Currently, I am using Emacs (and then install ESS) for running LaTeX and R from a same editor-program (like i was doing with Tinn-R in windows). Nevertheless, and even though i have been using Emacs for almost 2 years, it is not as

Dear R-help list, I am just trying to increase my memory for R, but for some reason I cannot really increase the memory size as much as I would like. I have 3 GB of RAM on a Windows XP (R 2.8.1) > memory.size() [1] 879.4667 > memory.size(T) [1] 1162.75 > memory.limit() [1] 3072 > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 421697 11.3 1476915 39.5 1476915 39.5 Vcells

The other day, CNN had a story on working at Google. Out of curiosity, I went to the Google employment web site (I'm not looking, but just curious). In perusing their job posts for statisticians, preference is given to those who use R and python. Other languages, S-Plus and something called SAS were listed as lower priorities. When I started using Python, I noted they have a portion of the

Hi All, I want to have an array/ matrix that looks this x<- 0 0 1 1 1 3 5 4 4 7 -1 8 9 10 6 I hope this makes sense. So basically if I want x[1,3] it will access 0 and similarly x[4,2], -1.

Hi All, I'm trying to create labels to plot such that it doesn't show up as scientific notation. So for example how do I get R to show 1e06 as $1,000,000. I was wondering if there was a single function which allows you to do that, the same way that as.Date() allows you to show in date format on a plot. Thanks, Sachin --- Please consider the environment before printing this email ---

Hi R, In the following code my x-axis is formatted in month format. Which Im happy with. The y-axis is what I want to re-format with something else. My question is, is it possible just to switch off the xaxis in plot function (see below). If not how do you get the months to show up as FEB-YYYY, MAR-YYYY and so on, so I could fit a label on x-axis. Thanks, Sachin p.s. sorry about corporate

Hi All, I have a date in the format of yymmdd (without any of the backslashes, eg. 100731). How do I convert this into a Rdate and plot it? I don't want the number of days from 1970's showing up as my date (Its the date I require). Thanks, Sachin p.s. sorry about the corporate notice I can't remove it. --- Please consider the environment before printing this email --- Allianz -

Hi all, Just following on from a previous thread (for loop). Is there a parallel 'for' loop like matlab (parfor maybe?). I know there was a Nvidia GPU version for blas somewhere. But is there a CPU or a GPU version of the for loop? Thanks, Sachin p.s. sorry about the corporate notice below: cant get rid of it. Don't have other mail client access at the office :( --- Please consider

Hey all, Suppose a=b^2 for starters. I want to be able to create a graph that displays a initially and if i was to click on 'a' to show 'b' on the chart itself. Does anyone know if this is possible in R? Also as an extension (not necessary as yet) to output the above into a 'html' file. Thanks, Sachin --- Please consider the environment before printing this email ---

Hi All, Currently my plot shows the y-axis in scientific notation (1e07 and so on). I want to be able to display this in dollars such that it shows $10,000,000 (including the commas). How do I do this. Also with the xlabel and ylabel. I've specified: 'title('Cash vs Time',xlab='Period',ylab=''); Im hoping that this will also not display anything on the y-axis.

Hi all, When I write out some values and then use 'plot' and 'lines' respectively I can get R to plot me two lines. However when I get the data from a csv file and run it I only manage to get one line running (whichever was invoked first). The sample files are attached below and I've reproduced the code below with the suspicious part marked as #??? (not even sure if thats

Hi All, I've reproduced the example from Prof. Friedrich Leisch's webpage. When I write sweave("Example-1.Snw") OR sweave("Example-1.Rnw"), (yes, I renamed them). I get the following error: Writing to file example-1.tex Processing code chunks ... 1 : echo term verbatim Error: chunk 1 Error in library(ctest) : there is no package called 'ctest' Also while

Hi All, I am trying to run R scripts on a server rather than my own machine. The biggest reason being that the data can be 3GB+; more than my RAM can handle. Anyway is there a way to do this. I am trying to find a SAS alternative. In SAS you can do (keyword) rsubmit; and get things running remotely on a server. Is there something similar on R. Couldn't find a comprehensive answer online.

Hi, I am new to R, and as a first exercise, I decided to try to implement an XIRR function using the secant method. I did a quick search and saw another posting that used the Bisection method but wanted to see if it was possible using the secant method. I would input a Cash Flow and Date vector as well as an initial guess. I hardcoded today's initial date so I could do checks in Excel.
