read "4-jan-02" as date
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.

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 <-

converting data to date format
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?

get.hist.quote does not work (PR#1116)
Full_Name: Arto Luoma Version: 1.3.1 OS: Windows 98 Submission from: (NULL) (153.1.53.119) Hi! The function get.hist.quote in the package tseries (Version 0.7-6) does not work in my computer.

Problems with weekday extraction from zoo objects
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:

Date vs date
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.

Read.dta and Write.dta Binary Data Error
Thanks in advance. I pass data sets between R and Stata and think dta files would be the best files for this. To do this I can use package foreign or package memisc. I mostly use foreign, although have used memisc and this problem mostly didn't happen, but created errors at other times. I have a csv data set (and created a test case) with with at least one column completely missing. This

Date vs date (long)
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
