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.

Dear R community I try to create a new operator to build a special sum of two CashFlows. (my S4 Class) I tried the following but this is actually not what I want. setGeneric("++",function(e1,e2)standardGeneric("++")) setMethod("+",signature=list("CashFlow","CashFlow"),function(e1,e2){ print("+") })

Dear R forum I have a data.frame as cashflow_df = data.frame(instrument = c("ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC", "ABC", "PQR", "PQR",

Hello! I'm not sure if I should have posted this to wine-devel or add bug in Bugzilla, so I'm posting this here. I've got following problem: I've upgraded Wine to 0.9.38, and Kiyosaki's Cashflow 101(http://appdb.winehq.org/appview.php?iAppId=2216) stopped working. Game crashes "in windows way" - with a Message box "Unhandled Exception: c0000005 At address:

Since I updated to Ubuntu 8.04 yesterday I have lost the UK short date format DDMMYYYY and am having a real problem setting it system wide. (I now have the US MMDDYYYY format.) Ubuntu 8.04 appears to ignore the LANG="en_GB.UTF-8" line in etc/environment which fixed the issue in 7.10. The apps I run on wine all use the short date format so here is my question. Is it possible to make wine

Hello. A few weeks ago, I need to calculate the Internal Rate of Return for irregular intervals. There is the package 'financial', with the function 'cashflow', calculating irr for regular intervals. So I developed xirr, managing irregular intervals, that's accepting a vector of dates as xirr Excel function. You can find the code at

I am trying, without success, to compile a custom locale for the utf-8 character set. I have issued this command: localedef --no-archive -f UTF-8 -i /usr/share/i18n/locales/en_CA at yyyy-mmm-dd en_CA at yyyy-mmm-dd.utf8 which produces the requisite files without reporting an error but which none-the-less insists on using the iso-8859-1 charset: LC_ALL=en_CA at yyyy-mm-dd locale charmap

Hello, I am trying to setup a samba4 AD dc in my network using smb-tool. Everything seems to work except DNS forwarding.

Hi, Presently I have the latest full backup in a 'current' directory and 30 day incrementals in 'YYYY-MM-DD' format directories. Without changing that directory structure I'd like the 'YYYY-DD-MM' directories to contain the full system hardlinked (when applicable) to 'current'. What rsync command-line options could provide me with this? Thanks,

Hi folks, I have been tormented for some time by Excel's habit of exporting dates to CSV files as mm/dd/yyyy format even if the dates are formatted dd/mm/yyyy in the display. What's worse, if there are dates that are of ambiguous (6/6/2011) and unambiguous (16/6/2011) format in the same column, Excel reformats the unambiguous dates and leaves the ambiguous ones as they were! Yesterday

Dear R-WinEdit users, I got a simple question, but somehow I cannot find the answer, although I have tried a lot! I got an ASCII-file and I want to import it into R, so that every character is defined by [i;j]. The rows are not of the same length. the file looks like the following shortened abstract example: name: xxxxx xxxx age: 9.9.99 record number: 999 title: xxxxx xxxx xxx keywords: xxx xx

Here are the functions I used: library(RODBC) channel<-odbcConnectExcel2007("myfile.xlsx") tmp<-sqlFetch(channel,"1",as.is=T) The dates in myfile.xlsx are all in this format: mm/dd/yyyy. But when I read it to R, some columns look like "yyyy-mm-dd 00:00:00", some columns look like "yyyy-mm-dd", and some

The US water year extends from 01 October yyyy-1 through 30 September yyyy and is referenced by the year starting on the included 01 January yyyy. I'd like to be able to find the annual means for the water year. To do so I've taken the input date-time, which is in the usual format "1991-10-07 10:35:00" changed it by: w$d<-as.POSIXct(w$date.time) Now I can add an
