problem in installing RcppBDT_0.2.1
Dear listers, I am trying to install RcppBDT_0.2.1 on my Windows machine using the function install.packages("./RcppBDT_0.2.1.tar.gz", repos=NULL, type="source"). Since this package is not like most of other packages in that it requires Rcpp and boost, I have installed Rcpp and boost first, and executed the install.packages function. Then, I got the following error message:

Conversión de objeto temporal (TS) a matriz (o data.frame)
Hola a todos: La pregunta ha quedado clara en el asunto, pero: ¿existe alguna función que convierta un objeto temporal (TS) a matriz o data.frame? En algunos cálculos que estoy haciendo me viene bien convertir un objeto temporal a matriz para poder hacer cálculos parciales por meses o años (aplicando apply en la matriz) pero no he encontrado ninguna función que haga la conversión.

ISOdate returns incorrect date?
Dear all, I have found the following (for me) incomprehensible behaviour of ISOdate (POSIXct): > ISOdate(1900,6,16) [1] "1900-06-15 14:00:00 Westeurop?ische Sommerzeit" > ISOdate(1950,6,16) [1] "1950-06-16 14:00:00 Westeurop?ische Sommerzeit" Note that in the first case I get the 15th of June back, not the 16th as I would have expected!

data manipulation
Hi, I am new to R, coming from a few years using Stata. I've been twisting my brain and checking several R and S references over the last few days to try to solve this data management problem: I have a data set with a unique patient identifier that is repeated along multiple rows, a variable with month of patient encounter, and a continous variable for cost of individual encounters. The data

R crashes when printing a named numeric vector of a specific class - Bug?
Dear useR's, today I stumbled over an interesting phenomenon: First, I created a named numeric vector with a certain class and several attributes via the structure() function. After that, I implemented a simple print method for this class. When calling this function it produces an endless loop of print calls until R crashes. :/ What is going on here? Is this a bug or have I done something

Issue with seek() on gzipped connections in R-devel
Dear all, In R-devel (2011-09-23 r57050), I'm running into a serious problem with seek()ing on connections opened with gzfile(). A warning is generated and the file position does not seek to the requested location. It doesn't seem to occur all the time - I tried to create a small example file to illustrate it, but the problem didn't occur. However, it can be seen with a file I use for

ISOdate() and strptime()
Dear R-people! I am using R 1.8.0, under Windows XP. While using ISOdate() and strptime(), I noticed the following behaviour when "wrong" arguments (e.g., months>12) are given to these functions: > ISOdate(year=2003,month=2,day=20) #ok [1] "2003-02-20 13:00:00 Westeurop?ische Normalzeit" > ISOdate(year=2003,month=2,day=30) #wrong day, but returns a value [1]

difftime / RBloomberg
hi, I've troubles with some difftime objects. e.g. ISOdate(2001, 4, 26) - ISOdate(2001, 2, 26) - 2 works, telling me "Time difference of 57 days". But when I'd like to add days, such as ISOdate(2001, 4, 26) - ISOdate(2001, 2, 26) + 2 the function gives me an error. Function "as.COMDate.chron" of the Rbloomberg package doesn't work for that reason. I'm

Lotos 1-2-3 date to POSIXct
I have some data that was created for import into a Lotus 1-2-3 spreadsheet and on of the columns is time. The time is akin to Julian were the value 1 is mapped "01-Jan-00 12:00:00 AM" in Lotus 1-2-3. Is there a function in an R package that can convert this numeric vector to a POSIXct vector?

Getting the last day of the month.
Hi, Given a date, how do I get the last date of that month? I have data in the form YYYYMM, that I've read as a date using > x$Date <- as.Date(ISOdate(substr(x$YearEnd,1,4),substr(x$YearEnd,5,6),1)) But this gives the first day of the month. To get the last day of the month, I tried > as.Date(as.yearmon(x$Date,frac=0)) But I don't get the last day of the month here. (Tried

readRDS and saveRDS
Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

Manipulating two large dataset differing by date and time
Dear Members, Compliments of the Season!! Below is a part of a code I use for Fourier analysis of signals. The code handles data with the format 05 01 01 8628 (year, month, day and count) 05 01 02 8589 (year, month, day and count) The sample data is attached as 2005daily.txt.

Non-GPL C (or R) inside of a package
R-devel, I am interested in creating a package that requires non-GPL'd (commercial) C code to work. In essence it is a single .c file with no use of R headers (all .C callable functions). For example's sake: 1 #include <stdio.h> 2 3 void test (int *a) { 4 *a = 101; 5 } The package isn't destined for CRAN, and I realize that this isn't R-legal, but looking for

formal vs. passed args: parent.frame() behavior.

Sorting a vector by date
Hello out there.... Again I have a problem and I stuck... How can I sort a vector of dates? For example I have the vector a<-ISOdate(2001, 1, 1) + 70*86400*runif(10) How can this vector be sorted chronological? And what's the function I should work with to handle these entries? (in sense of: which(a>2001-01-04) or somehting like that) Thank you for helping M.Kirschbaum
