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? [[alternative HTML version deleted]]

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}}

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 ?")

...e 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?

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
