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. Thanks, Rob

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) Regards, Pierre Lapointe ************************************************** AVIS DE NON-RESPONSABILITE: Ce document transmis par courrie...{{dropped}}

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", "3071960") strptime(x, &...

...Aug56, or August 31 1956. Usage: as.date(x, order = "mdy", ...) Value: For each date, the number of days between it and January 1, 1960. The date will be missing if the string is not interpretable. But here is what happens when you actually use it: > as.date(c("1jan1960")) [1] 1Jan60 Can somebody explain this? Also please suggest me the best function in R to convert from as.Date("2009-08-13") to Julian and vice versa. Regards Utkarsh

...7 which is May 7th 2007. Is there any particular function to extract just the year from this format? When I am reading this data from a text file it is reading it correctly in the same format but does not acknowlede it as date but as a factor. If I try as.date(5/7/2007) then it is converting it to 1Jan1960. Weird it is. Any help on that front? Any help is greatly appreciated. [[alternative HTML version deleted]]

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 ?")

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
