Hi? I have setup a samba 4 DC with mixed client environment. My problem is that the mac osx client are unable to write to a samba 4 share. I tested mac osx clients on a normal windows 7 share and it works fine I tested mac osx clients on a samba 3.5 .. share and everything works fine. As i am in a professional environment and all the windows clients are already binded to the samba 4 domain i

Hi All In trying to correlate some tide gauge data I need to deal with varying timezones. From the documentation on strptime, it seemed that the tz variable might have some effect on the conversion, but I'm not seeing an effect. > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="PST")+0 [1] "2006-12-01 01:02:00 EST" >

Hi R Devel, I just ran into a corner case with 'strptime'. Recall that the "%OS" conversion accepts fractional seconds: > strptime("17_35_14.01234.mp3","%H_%M_%OS.mp3")$sec [1] 14.01234 Unfortunately for my application it seems to be "greedy", in that it tries to parse a decimal point which might belong to the rest of the format: >

Hi, I am having a trouble parsing dates using strptime() that I get in the format of year and week number. The data looks like this "201127" which means year 2011 and week 27. I would like to graph this using ggplot but then I get a gap between 201054 and 201101 so I thought I would just easily convert it. I tried to use strptime and as.Date and the format string of %Y%W but it seems

Converting date strings that range between Mar-14-2010 2:00 and Mar-14-2010 2:59 (inclusive) to date objects (POSIX) returns a NA entity: > strptime("3/14/2010 2:00",format="%m/%d/%Y %H:%M") [1] "2010-03-14 02:00:00" This looks fine, however other functions such as plot see a NA object instead: > is.na(strptime("3/14/2010

Full_Name: Bill Hutchison Version: 2.2.1 OS: Windows XP Submission from: (NULL) (69.158.121.13) example(strptime) produces the following error: Error in strptime(x, "%d%b%Y") : 2 arguments passed to 'strptime' which requires 3 This error occurs wherever strptime is used. It does not occur in 2.2.0

Hi everyone, I have bunch of date and time observations in the format %Y-%m-%d %I %M %S %p. I used strptime() to read this format. But the problem is some of the times are in the format of %I %M %p, so for those times, strptime is giving me NA values. For example, strptime(paste("2009-04-08","1:49:47 PM"),format="%Y-%m-%d %I:%M:%S %p") [1] "2009-04-08

R V2.0.1 on Windows XP. I have read the help pages on strptime() over and over, but can't understand why strptime() is producing the following results. > v <- format("2002-11-31", format="%Y-%m-%d") > v [1] "2002-11-31" > factor(v, levels=v) [1] 2002-11-31 Levels: 2002-11-31 > x <- strptime("2002-11-31",

Hi, I have a column in a dataframe in the form of: > as.vector(SLDATX[1:20]) [1] "1/6/1986" "1/17/1986" "2/2/1986" "2/4/1986" "2/4/1986" [6] "2/21/1986" "3/6/1986" "3/25/1986" "4/6/1986" "4/10/1986" [11] "4/23/1986" "4/30/1986" "5/8/1986"

I'm trying to proess date/time fields from files that were given to me to analyze. Any clues what I'm doing wrong with strptime? This seems to fail the same way under Linux or Windows. For ?strptime would it make sense to explain %OS3 somewhere besides the Examples? > # Why does %OS3 work here? > format(Sys.time(), "%H:%M:%S") [1] "16:45:19" >

The example from the help page for strptime has the following oddity: > dates <- c("02/27/92", "02/27/92", "01/14/92", + "02/28/92", "02/01/92") > times <- c("23:03:20", "22:29:56", "01:03:30", + "18:21:03", "16:56:26") > x <-

Hello, strptime is still not working correctly in my computer (Windows 98 and R Version 1.3.1) From x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960") strptime(x, "%d%b%Y") I obtain [1] "NA" "NA" "NA" "NA" while x <- c("01011960", "02011960", "3131960",

I read a dataset with times in them, e.g., "09:31:29.18761". I then parse them: > all$X.Time <- strptime(all$X.Time, format = "%H:%M:%OS6"); and get a vector of NAs (how do I check that except for a visual inspection?) then I do > options("digits.secs"=6); > all$X.Time <- strptime(all$X.Time, format = "%H:%M:%OS"); and it, apparently, works:

Dear R-people! I am using R 1.8.0, under Windows XP. What I want to do is a date conversion of a character column of a data frame and assign the result as a new column. Simple example: > x <- data.frame(a=c("yesterday","today","tomorrow"), b=I(c("20031111", "20031112", "20031113"))) # convert x$b from character to date: >

Hi, I'm experiencing a problem with strptime. (R 1.9.1 on a Win2000 machine) I have a large list containing 6 columns and 161800 rows. One column contains dates that I want to convert in order to compare the different dates. Some dates work just fine while others become NA. I don't see any difference between the dates. I've attached an example from my code. Hope this explains my
