similar to: as.Date() behaviour when incomplete input string

Hello, I was hoping for advice regarding resolving the above error. I have a csv file that contains the following variable: $ Order.Made.Date : Factor w/ 299 levels "1-Apr-08","1-Aug-05",..: 278 285 91 286 159 132 108 261 282 147 ... I want to calculate a variable named F.length, which is today's date minus the values contained in the variable:

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 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 Brian, I dont understand what you mean. The thread was about the as.Date which you suggested to be used instead of the as.date. Following your advice I tried the as.Date and have questions about the observed behaviour, which was surprising to me. Is this what you call hijacking? Do you mean I ought start a new thread instead? I thought my question were relevant to the threads'

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

In the base package, as.POSIXct() is an S3 generic function, but as.POSIXlt() is not. As shown below, the current implementation is already crying out to be refactored into a generic function with methods for various classes. It calls "inherits" five times. Not only is this bad style, it also disallows me or anyone else from making as.POSIXlt() work with other kinds of time-ish

Peter et al Thanks for the comments on dates. Some of the respondents missed the point, by showing ways that I could work around the problems, when my main argument is that one shouldn't have to work around problems. So I hereto present round 2 of the debate. 1 Postulates a. In my 35 year computing experience, I think that nothing frustrates me more than a computer program that

Dear all, The as.Date() function appears to give different results depending on the order of the vector passed into it. d1 = c("1900-01-01", "2007-01-01","","2001-05-03") d2 = c("", "1900-01-01", "2007-01-01","2001-05-03") as.Date(d1) # gives correct results as.Date(d2) # fails with error (* see below) This problem

Dear all, I successfully set up a local MySQL-database. Connecting via RODBC is not problem, the same in fetching 3 of 4 tables.

Hello all, I recently moved from the US to Africa & on changing my time zone in the OSX system preferences from EST to GMT+3 ( East Africa) on attempting to use read.dta using the foreign package began getting an error of: "Error in fromchar(x) : character string is not in a standard unambiguous format" This error goes away & the data is correctly read in when

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

Hi ALL: I am trying to use get.help.quote from library(tseries). I tried to run the example from help(get.hist.quote) but R complained. Here is the command I used and the response: ibm <- get.hist.quote(instrument = "ibm", start = "1998-01-01") trying URL

Hi, i really positive surprised when i found the "get.hist.quote" but didn't now why i get with the examples from Online-Help errorMessages. Perhaps their is a problem with POSIX and my OS WIN2000/R1.5.1 ? Thanks for advance & regards,Christian $ ibm <- get.hist.quote(instrument = "ibm", start = "1998-01-01") trying URL `

Dear list, I know this is really basic question but I just couldn't get anything to work. (I did a R site search with keywords "zoo" and "data frame" but the server timed out on me.) I have a time series which has the following (typical) format, DATE Open High Low Close Volume 01-JAN-2006 5.25 5.25

Hi Folks! I'm struggling with dates - but enough about my personal life..... I have two daily time series files. In one (x) the date format is Y/m/d and the other (y) is d/m/y. I used read.zoo on both and they read into R with no problem. Then I use: weekdays(as.Date(x$DATE)) and get what I expect - all the days of the week in my data set. When I use:
