similar to: Unexpected behaviour of the as.Date (was: Error as.Date on Invalid Dates)

Hi All, I have an script in R which accepts user inputs for certain parameters, particularly dates, which the user inputs as character strings. eg: > date1 <- "2009-01-21" The script later parses the input via the as.Date function: > as.Date(date1) However, as.Date encounters an error when the string does not represent an actual date. eg: > date1 <-

Dear list, Is there any functionality in R that would allow me to parse config files? I have trie ??config and apropos('config') without succes, and also search the R package site. Mvh. Marie [[alternative HTML version deleted]]

Dear list, I have a vector of elements which I want to combined each with each, but none with itself. For example, > v <- c("a", "b", "c") and I need a function 'combine' such that > combine(v) [[1]] [1] "a" "b" [[2]] [1] "a" "b" [[3]] [1] "b" "c" I am not very interested in the orders

Dear useRs, I have a collection of source file and some of these call others. The files are distribute among a number of directories, and to know how to call some other file they need to know what file is currently executed. As example, I have a file 'search.R' located in directory 'bin' which needs to access the file 'terms.conf' located in the directory 'conf',

Dear R, I have find a website where they report problem with ARIMA models in R. I run the examples there and they give result as shown on the website. Does this mean that nothing has corrected in R? Maybe you not have seen the page, but the author said he contacted you. Here is the URL: http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm I like to know your opinion. Mvh. Marie [[alternative

Dear List, I try to develop code where plotting functions are embeded in my own functions. The following is simplified example: > test <- function() { > data <- data.frame(x=rep(1:2, each=50), y=rnorm(100)) > library(lattice) > attach(data) > xyplot(y~x) > detach() >} >test() As far as I understand R, when test is called this should create one local

I'm currently working on hardware construction library for C++ (similar to Chisel (which is written in Scala)). And since C++ has no standardized reflection, I use DWARF as a source of reflection metadata. And in case of

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!

Hey there all, Is there some way to tell rails or sql server to ignore the time in a datetime field when doing a comparison? For example, if I do something like select * from users where registration_date = ?, @date where @date might equal some user input like ''03/14/2006'' The result is nothing returned, because in my tables the datetime field looks like this: 3/14/2006

Dear R users, I have a column with dates (character) in a data frame: 12-Jan-01 11-Jan-01 10-Jan-01 9-Jan-01 8-Jan-01 5-Jan-01 and I need to convert them to (Julian) dates so that I can sort the whole data frame by date. I thought it would be very simple, but after checking the documentation and the list I still don't have something that works. 1. as.Date returns the error below. What am I

Dear all, I import my data from a csv-file containing one row with date-entries. How can I tell R to treat this data as dates? I've tried to bring it in character-format (as.charachter()) followed by as.POSIXlt() but I get an error message, that the character string is not in a standard unambiguous format, although the date is of format yyyy-mm-dd (what is standard format according to R

Hello I have a huge file (not an R-file) in which the first column is a string with date, hour, minutes and seconds (For instance, "31-Jul-2010 23:59:00"). I tried as.Date but the error msg was "Error in charToDate(x) : character string is not in a standard unambiguous format". I have checked the help for the function as well as date but to no avail. How can that sort

Hello - I have a csv file with a few date columns. Some of the records have an "NA" character string instead of the date. When I attempt to use read.csv() and typecast the columns using colClasses, I receive the following error: Error in charToDate(x) : character string is not in a standard unambiguous format Similarly, the following command produces the same error:

Dear R Gurus: I read somewhere that functions are considered vectors. Is this true, please? thanks Edna Bell

Hi, I understand this should be an easy task but I am still struggling a bit to read a .txt file with a date vector. My code is as below: data<-read.table(file.choose(),header=TRUE,sep="\t",dec=",",colClasses=c("Date","numeric","numeric","numeric")) But I am getting an error: Error in charToDate(x) : character string is not in a

I wrote the date package long ago, and it has been useful. In my current task of reunifying the R (Tom Lumley) and Splus (me) code trees for survival, I'm removing the explicit dependence on 'date' objects from the expected survival routines so that they better integrate. Comparison of 'date' to 'Date' has raised a couple of questions. Clearly Date is more

I don't understand how extra vtable ref DIE will help in case on non-polymorphic classes. If you remove virtual destructor from example, vtable won't be generated for class, but DWARF will still have incorrect ambiguous names for types. It will become a problem when you need to use debuginfo as a C++ runtime reflection (I've already seen this in a couple of projects). Or when you need
