search for: datestring

For the r script below >datestr <- "01/01/2004" >as.POSIXct(as.Date(datestr, "%d/%m/%Y")) I get the following output "2003-12-31 18:00:00 Central Standard Time" Why is the date a day before. I guess its something to do with the time, but is there a way to get it to return 2004-01-01 instead? Thanks in advance... -Sandeep [[alternative HTML version

I am trying to download a bunch of files from a server, for which I am using download.file( ) within a for loop. The script is working fine except until download.file hits a URL which has no file, at which point it exits. I want to change this behavior to simple log the failure and maintain state within the for loop and iterate to next. I read about try / tryCatch but am having trouble

Hi, I''m stuck. How do you parse a "dd/mm/yyyy" formatted date string??? I get a date format error.

Gabor, Thanks much. Your solution is elegant. My overall scheme is to take present date, and check whether it is a weekend, if not, then create a string based on the date, to concatenate into a url link for download.file( ). The files I need to download have a part which is in the format: mmddyy. I am working to make myself a system to connect to exchanges, and download end of day files from

Hello I am new to R and I need to convert some dates (numeric format by matlab) to actual dates in R. For instance, Matlab -> 730456 -> >> datestr(730456) ans = 02-Dec-1999 R - > library(zoo) > as.Date(730456) [1] "3969-12-03" I don't not mind the output format but it needs to be right. Many thanks Ed

Hello, I am running Samba 2.2.3a-6 on a Debian(testing) machine. It is running as a PDC for 15 Win2K(SP2/3) systems. Everything runs beautifully except the users cannot change their passwds. When a user CTRL-ALT-DEL and change passwd they ultimately get a messages stating that the old passwd is incorrect.... If I log into a shell as a user on the system and invoke smbpasswd, It goes through all

Hi all, Please, how could I calculate the time that two time segments has in common? Is there any function to perform this calculation? For instance, given four POSIXlt objects... endPeriod<-as.POSIXlt("2008-09-30") startPeriod<-as.POSIXlt("2007-10-01") endProject<-as.POSIXlt("2007-05-31") startProject<-as.POSIXlt("2006-12-01") that limit

hey, i need to know who deleted files on our server so i added the audit module. but now i cant find any hint in the log file which user deleted the file. it just shows me "Feb 6 13:54:57 smb.-server smbd_audit[13881]: opendir .recycle". How can i do that? another question is: how can i tell samba to keep more versions of the log files? Now it only keeps a client.log and a

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems

Hello, I have a zoo time series object (say a) with the following time stamp/format [1] "1950-01-03 GMT" "1950-01-04 GMT" "1950-01-05 GMT" "1950-01-06 GMT" [5] "1950-01-09 GMT" "1950-01-10 GMT" and another (say b) with [1] "1950-01-05" "1950-01-06" "1950-01-09" "1950-01-10"

Hello again folks, Thanks to all for the advice on getting hold of "grid" and "lattice". I think I'm getting the hang of it. This produces very satisfying arrays of histograms. The typical command I am using is histogram( ~ DATA.df$X | DATA.df$F, \ type=c("count"), layout=c(5,5) ) Now I'd like to ask a question slightly more subtle than

Hi All, I am addressing this post to all who are new to R. When learing R in the last weeks I took some notes for myself to have code snippets ready for the data analysis process. I put these snippets together as a script template for future use. Almost all of the given command prototypes are tested. The template script contains snippets for best practices and leaves out the commands that
