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, 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",

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

Hi everyone, I have been trying to compute numbers of days between two dates as follows: > x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960") > z <- format(x, "%d%b%Y") > ex <- c("1jan1961", "15jan1960", "21mar1975", "10jul1981") > ez <- format(ex, "%d%b%Y") > ez-z

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

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 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. > x <- c("1jan1960",

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

To Whom It May Concern: The following appears to be a bug in the way POSIXct dates are formated. The example is forced, but occurs naturally when importing Excel type dates (where fractional part is fraction of a day) and small rounding errors result. As shown, looking at the POSIXct class, it looks as if both times are 16:11:03 (truncation) Looking at as.numeric.POSIXct, it looks as if

Dear All, I am trying to convert to POSIXct after pasting a date and a time in character format with strptime. It is probably obvious but I don't understand why I get an error message after bsamp$spltime<-strptime(test,format="%d-%B-%y %H:%M") whereas I can get what I want if I do it in 2 steps and rbinding ? Thanks and best regards, Jean-Louis This is the R console output

Hi Tomas, Many thanks for your answer. Here is a copy of a fresh session under RStudio, and after a copy under Rgui. Strangely enough the result of memory.limit() is not the same. Without your question I would not have looked to RGui, being used to work with RStudio. The value under RGui sounds to correspond to the total RAM of the computer. It makes me noticing that the value is in MB.

Hi, I am not not sure whether this topic belongs to this mail list, but I feel the subscribers here should be the right audience. I noticed that the memory limit reported under Windows is 16 GB. I am wondering how to increase it. I didn't found anything in Rprofile.site nor .Rprofile. Is this limit hard coded at compilation? Best, Samuel [[alternative HTML version deleted]]

Dear list, I have encountered a special case for searching a linear regression where I'm not satisfied with the results obtained using the traditional least squares method (sometimes called OLS) for estimating/optimizing the residues to the regression line (see code below). Basically, a group of my x-y data are a bit off the diagonal line (in my case the diagonal represents the ideal or

Dear list, I?m using R embedded in another program (coded in tcl/tk) under Windows Vista. In this context I don?t launch Rgui.exe but rather Rtem.exe. Now I have a problem finding libraries not specifically installed as administrator (and which are not in the path ?program files? but in Contacts\Documents of the current user). To be precise, the user launching my tcl/tk program can?t find

Full_Name: Zivan Karaman Version: 2.7.2 OS: Windows XP Submission from: (NULL) (195.6.68.214) I'm puzzled by the readRegistry function. Shouldn't the "hive" argument be something like c("HLM", "HCR", "HCU", "HU", "HCC", "HPD") rather than c("HLM", "HCR", "HCU", "HU",

Hi, I am having trouble extracting just the year or the month or the day from a date such as 5/7/2007 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

Dear guRus, I'd like to learn how to make a function recognize the name of an object/vector given as argument If I have : testFun <- function(x,y) plot(x,y, main=paste("plot of",names(x),"and",names(y)) ) # this just a simple example ... a1 <- 5:8 b1 <- 9:6 testFun(a1,b1) # Returns the plot, but not the names of the objects/vectors given as arguments, # but
