I have a view with two auto complete input boxes. How do I give the input a name like I can for "text_input" helper? I''ve looked at the docs (http://api.rubyonrails.com/classes/ActionView/Helpers/JavaScriptMacrosHelper.html#M000462) but cant make sense of it... <p><label for="search_start_station">From</label><br/> <%=

Dear all, I hope this is a right place to post this; r-help might be appropriate but it looks like I'm suggesting a change in base package, so I decided to post here. (+ Apologies if that has been changed recently -- the version I'm using is R.2.12.2 on Windows.) I've noticed an unexpected behavior of trunc.POSIXt: foo <- seq(as.POSIXct( "2009-10-23 22:00:00"),

Dear all, I am working with a list of objects each of which contains two POSIXct objects (say, $Start and $End) and a number of different data in addition to that. Now an easy way to extract Start times of all object could be sapply(x, "[", "Start") but this converts them all to numeric, and so does sapply(x, "[[", "Start"). lapply preserves the class but

Hi, I need to do some analysis on historic daily radiosonde data I download from the Wyoming Univ. web page ( http://weather.uwyo.edu/upperair/sounding.html). I am trying to use the RadioSonde package (V 1.3), but the format of the files from Wyoming don't match what RadioSonde is expecting. Has anyone used the Radiosonde package on the Wyoming data? Here is a sample of the Wyoming file

Hi there, We have plans to install an office (not call center) with the following setup: 200 linksys 942 phones (sip + g711) on a LAN a server with a dual port E1 sangoma and a remora card with 4 fxo modules. So far when we want to setup a linksys phone, we need to use the http interface of each phone, disable/enable a lot of things and plug it into the network. this is not the best scenario for

Hi folks out there, I'm new to this project but very keen on more information. The reason I want to have Wine, is because I want to get "Klingon Academy" on OS X. On every Windows Revision above Win 98 the game fails, so I thought: "Why not do it the other way around and try Wine?" So, here I am. And after the first look into the Wiki page, I was VERY confused on how I

Hi, I was trying like to print out data frame with POSIXct column in html format using xtable package, but I got error message when trying to print the table. Here is example: aaa<-data.frame(as.POSIXct(strptime('03 2005', '%d %Y')),0) aaa.tab<-xtable(aaa) print(aaa.tab) Error in Math.POSIXt(x + ifelse(x == 0, 1, 0)) : abs not defined for POSIXt objects

Hi guys. The 'col'-parameter in the 'hist'-method for the classes 'POSIXt' and 'date' does not perform as it does in the default 'hist'-method. Unfortunately, it does not only change the filling color of the boxes, but also the color of the axislines. [Using 'graphics'-package version 2.2.0] Examples: # with POSIXct-object hist(.leap.seconds,

Hi all, I'm plotting a histogram of dates and would like to shade the bars, e.g. hist(.leap.seconds,"years",col='gray',freq=T) -but the axis color also changes, how do I prevent that? thx in advance Janus [[alternative HTML version deleted]]

Full_Name: andrea capodicasa Version: 1.7.0 OS: w2k sp3 Submission from: (NULL) (212.17.194.154) Hi all, the problem is when you try to round.Posix an empty vector of dates Please give a look to this code: > data=seq(ISOdate(2001,1,1),by="day",length=3) > data [1] "2001-01-01 13:00:00 ora solare Europa occidentale" [2] "2001-01-02 13:00:00 ora solare Europa

Hello! na.encode does not have any effect on format of NA values of Date and POSIXct (POSIXlt?) "atomic" classes in a data.frame. Here is the example (the same in R 2.3.1 and 2.5.0 (2006-09-19 r39409)): testData <- data.frame(num=c(NA, 2.6), int=c(1, NA), fac=factor(c(NA, "abc")), cha=c("a",

Hello, ?DateTimeClasses states that "one can add or subtract a number of seconds or a 'difftime' object from a date-time object, but not add two date-time objects." So, is the below expected behavior? > x <- Sys.time() > x [1] "2007-02-21 16:19:56 CST" > x + as.difftime("1","%H") [1] "2007-02-21 16:19:57 CST" Warning

x <- seq(as.POSIXct("2000-01-01"), by = "days", length = 20) cut(x, breaks = 3) # Error in `levels<-.factor`(`*tmp*`, value = character(0)) : # number of levels differs cut(as.Date(x), breaks = 3) # Error in `levels<-.factor`(`*tmp*`, value = character(0)) : # number of levels differs Index: base/R/datetime.R

For certain values, round.POSIXt(tm,'day') does not round to midnight as documented. The reason is that trunc.POSIXt() does not adjust the value of the isdst element. Assuming my assessment of the reason is correct, I have a potential solution to offer. Additional discussion is in bug report #1543. -Don > x <- c(as.POSIXct('2001-4-1 3:15'),as.POSIXct('2001-5-2

There seems to be a problem in the way `+` is dispatched for POSIXt/difftime (R 2.8.0 Windows). With the following definitions: t0 <- as.POSIXct('2009-01-01 00:00') halfhour.mins <- as.difftime(30,units='mins') I would have thought that the straightforward answer to Suresh's question would be something like t0 + halfhour.mins * (0:47) And indeed, if we

I am still experiencing problems with seq.POSIXt() missing off the last day of the series: > seq(as.POSIXct("2004-03-25"),as.POSIXct("2004-03-31"),by="DSTdays") [1] "2004-03-25 GMT Standard Time" "2004-03-26 GMT Standard Time" "2004-03-27 GMT Standard Time" [4] "2004-03-28 GMT Standard Time" "2004-03-29 GMT Daylight

Dear all, according to the Help-page of DateTimeClasses {base} I should be able to do time - z with time date-time objects z a numeric vector (in seconds) or an object of class "difftime". However, on R version 2.6.0 (Windows XP) I get > Sys.time() - as.difftime(c("0:3:20", "11:23:15")) Time differences in mins [1] 1191837998 1191837318

I have found what looks like a small problem in trunc.POSIXt() involving the transition to/from standard time and daylight savings time. Assuming my assessment is correct, I have a potential solution to offer. If a time in daylight savings time is rounded such that the rounded value is on the other side of the transition, the isdst element does not get changed accordingly. I have tested only

Hi all, This summer I've been working with a grad student to bring more of the date time classes from JODA (http://joda-time.sourceforge.net/) into R. To make these work seamlessly with existing date time objects, we need to patch +.POSIXt. (The ruby community uses the term monkey-patching for this sort of ill-advised, by sometimes necessary, internal hackery, hence the title.) The problem is
