problem with strptime example (and mention of bug.report) (PR#811)
Hi,
The help file for strptime has the following code which doesn't work
for me:
## read in date info in format `ddmmmyyyy'
x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
z <- strptime(x, "%d%b%Y")
> z
[1] "NA" "NA" "NA" "NA"
Do these work for other people?

problem with strptime example (PR#811)
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",

Function as.Date leading to error implying that strptime requires 3 arguments
I'm using R V 2.2.1. When I try an example from the as.Date help page,
I get an error.
> x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
> z <- as.Date(x, "%d%b%Y")
Error in strptime(x, format) : 2 arguments passed to 'strptime' which
requires 3

Any suggestions would be appreciated.

as.POSIXct month problem
Hi everybody
When I try example of strptime
x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
z <- strptime(x, "%d%b%Y")
The result is;
> z
[1] NA NA NA NA
I have got the same result with complete form of month but not with numeric
form.
Any idea?

strptime problems
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

Change the language of the labels in a graph
Hello,
How do you change the language of the labels in a graph. In this example, I
want to get French labels by changing Sys.putenv. I should get "Mai"
instead of "May".
Sys.putenv(LANGUAGE="fr")
x <- as.Date(c("1jan1960", "2jan1960", "31mar1960", "30jul1960"), "%d%b%Y")
y <-1:4
plot(x,y)

Dear friends. Library Date was updated recently. I do not remember having
seen the error below until now ? The plot title is made appropriately but
the error message may be annoying, right ? I use version 1.1 on windows 98.
library(date)
tt <- as.date(c("1jan1960", "2jan1960", "31mar1960", "30jul1960"))
plot(tt,c(1:4),main="How's that ?")

as.Date
Hi. I'm sure this is a complete green-horn question. I apologize.
I'm trying to use as.Date *exactly* as shown on p. 194 of the manual (code
fragment and error message pasted below). Is there some kind of "include"
or "import" statement that I need to issue? Thank you very much for saving
what remains of my hair.

Configuring 2.2.2 (or 2.0.7) on Digital Unix 4.0f fails - "No locking"

running 4.0d, I receive the following error:
ERROR: No locking available. Running Samba would be unsafe

Regression in strptime
This is definitely obscure but we had a unit test that called
.Internal(strptime, "1942/01/01", %Y/%m/%d") with timezone (TZ) set to
CET. In R-3.1.3 that returned "1942-01-01 CEST" which, paradoxically, is
correct as they evidently did strange things in Germany during the war
period. Java also returns the same. However, R-3.2.4 returns "1942-01-01
CET".

Does strptime(...,tz="GMT") do anything?
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.

bug with strptime, %OS, and "."
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:

trouble parsing a date using strptime()
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
