Problem with timeSequence {timeDate} - wrong end date
Dear help-list,
I have a problem with timeSequence {timeDate}.
When I use it like

calendar-based time-series in R
Hello,
I am trying to switch to R from S-PLUS 6.1, and one problem I am having is
using R for manipulation of calendar-based time-series. In S-PLUS, I
commonly use the functions timeSequence(), timeDate(), and timeSeries() to
align/average/aggregate data; and I also do a lot of plotting of
time-series data (with calendar-based labels on the x-axis).
I was wondering if anyone is familiar with

Identifying US holidays
Hello!
I am trying to identify which ones of a vector of dates are US
holidays. And, ideally, which is which. And I do not know (a-priori)
which dates those should be.
I have, for example:
x<-seq(as.Date("2011-01-01"),as.Date("2011-12-31"),by="day")
(x)
I think chron should help me here - but maybe I am not using it properly:

date sequencing using the Fcalendar package
I am using the following command from the Fcalendar Package :
x = timeSequence("1992-12-31","1994-12-31")
and then y = as.character(x) is a vector of character strings
"[1] 1992-12-31" "1993-01-31" "1993-03-03" "1993-03-31" "1993-05-01" etc
This is very close to what I need and thank you very much

Can I create a timeDate object using only year and week of the year values?
For a model I am working on, I have samples organized by year and week of
the year. For this model, the data (year and week) comes from the basic
sample data, but I require a value representing the amount of time since the
sample was taken (actually, for the purpose of the model, it is sufficient
to use the number of weeks from the middle of the sample week to the
present).

library(fCalendar) timeDate("12.03.2005",format="%d.%m.%Y")
Dear R users,
I have problem with the library fCalendar.
I am not using the US standard format notations. It seems like it is not
possible to have different format than the US standards.
Anyone how knows a way to go around this problem?
Here is the code I enter:
myDate = "12.03.2005"
timeDate(myDate, format = "%d.%m.%Y")
And I get following error message:

use of apply in a data frame on a row by row basis
Hello all,
I'm trying to use the apply function on a data frame,
by applying a function that takes a one row data.frame as argument .
Here's the example :

df = data.frame(f1 = c(1,4,10),f2 = "hello")
apply(df,1,myfun) ==> Does not work (I get "character(0)" )
Though : myfun(df[1,]) works,
and myfun(df) works as well.

R timeDate does not allow seconds?
Hello, Sorry if anyone gets this message twice, as my mailserver may not
be working.
Thanks for your response. Your idea makes a lot of sense to me, but I've
been unable to get seconds to work.
I ended up with this format finally:
"2007-10-31_16:20:22"
Problem is I am unable to get it recognized as a date using timeDate():

timeSeq and TimeDate analog in R ?
Hi All : I am attempting tomove a large amount of code from Splus to R and I was hoping that there was an equivalent in R of the Splus functions timeSeq and timeDate ?
I did an RSiteSearch but nothing came up ?
If the equivalent functions are part of some package, that's fine.
Thanks a lot.

Efficient coding
I have a piece of code as the one at the bottom, unfortunately since it involves time series from a db it's not easy to give to mailing list a working script.
It becomes very slow after few hundred iterations over variable sp (must process several thousands).
The Rprof() indicates that the problem is the use of gc(). Can someone indicate what I have to take care of not to call gc() so often?
