Time arithmetic
...there a calendar system in R? I have written a function to add months to a date and return the number of days resulting. I am newish to R so I am hoping there is a package that can do this sort of date arithmetic for me... Worik DaysInMonths <- function(s,d){ ## Days in d months from s sdate <- MSTD(s) ## Get day, month and the year sd <- as.double(days(sdate)) sm <- as.double(months(sdate)) sy <- as.double.difftime(years(sdate)) sm <- sm+d while(sm > 12){ sm <- sm-12 sy <- sy+1 } sdate2 <- MSTD(paste(sd,sm,sy,sep="/")) r...

Problem with strptime generating missing values where none appear to exist
...es between two vectors of times. I have apparently no difficulty to convert the vectors to the appropriate format using strptime. But, then difftime does not calculate all the differences. Here is the code and output:- dob=strptime(as.character(datx$BDT),'%d-%b-%y'); dob$year=dob$year-100 sdate=strptime(as.character(datx$SDT),'%d-%b-%y') head(dob); head(sdate) [1] "1922-07-14" "1922-07-14" "1922-07-14" "1922-07-14" "1921-03-23" "1921-03-23" [1] "2001-08-27" "2001-08-27" "2001-08-27" "200...

increase number of ticks on x axis of dates
My x axis is a series of daily dates (e.g., 01/01/2000, 01/02/2000, etc.) from 2000 to end of 2008. The default only gives me 4 ticks. I want more. Why doesn't this work? sdate<-as.POSIXct(strptime(date,format="%m/%d/%Y")) plot(ppt~sdate,type="l",ylim=c(0,47),col=1,lwd=1,pch=16,ylab="Salinity, psu",xlab="Year",las=1,main="Duck Key Salinity",xaxt="n") year.text=c("2001","2002",&quo...

sdate<-as.POSIXct(strptime(date,format="%m/%d/%Y %H:%M"))
...strptime and the package CHRON, but still can't get there. My simple task is that I want to plot salinity (S1 or S2) on y-axis and time on x-axis, but I want to use a lay-understandable representation of time (not Julian). If I use the following command, I can make a plot using "plot(S1~sdate)", where: sdate<-as.POSIXct(strptime(date,format="%m/%d/%Y %H:%M")) ... however, every 00:00 time winds up being an NA. Here is an excerpt of the input data (this is a HUGE file): index Date Julian S1 S2 24985 11/19/2006 00:00...

colnames
Hi, I have a matrix with column names starting with a character in [0-9]. After some matrix operations (e.g. copy to another matrix), R seems to add a character 'X' in front of the column name. Is this a normal default behaviour of R? Why has it got this behaviour? Can it be changed? What would be the side effect? Thank you. Regards, Gilbert [[alternative HTML version deleted]]

subtracting 100 from strptime year vector generates missing values in POSIXct where none appear to exist in strptime year vector
...subtracting the 100? Good thought - if I use difftime before subtracting 100 from dob$year, then there are no missing values! But, it is not at all obvious to me why this should be so. Here are dob$years for the dates that go through OK after subtracting 100:- > table(dob$year[!is.na(difftime(sdate,dob))]) 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 42 43 46 48 2 12 18 20 24 32 40 52 44 16 30 20 40 62 41 46 60 33 15 16 28 21 23 16 16 4 4 4 4 and now here are the values for the dates that generate missing values:- > table(dob$year[is.na(difftime(sdate,d...

Question regarding sqldf
Hello, I am having a problem using sqldf. I'm trying to choose a subset of observations from a data set based on the date and maximum value of a variable by date. Here is the code I am using: test<-sqldf("select distinct * from bextuse group by sdate having bext=max(bext)",method="raw"); The result I get back is a data frame with 0 rows and 0 columns. I have tried the code in another program that utilizes SQL, and I retrieve the 14 rows I was expecting to get. I looked at the SQLite information on the web, and it mentions that...

day, month, year functions
...I'm aware of the weekdays() and months() functions in the base package. But they return a character object which requires some coding to convert into a numeric value. I've also tried the sday.of.week() in fCalendar but it doesn't like my date, > sday.of.week(xx) Error in Ops.Date(sdates, 10000) : %/% not defined for Date objects Do these functions exist in some package I'm not aware of?
