I have a vector that contains month and year in the format YYYYMM (e.g.“200701”, “200702”) I wish to do to things: 1. I need to convert to a date that is the last calendar day of each month. 2. I need to convert this to a date that is the last U.S. stock-exchange trading day of each month. Any advice is appreciated, mymonths <- c(200701, 200702)

Hi, Given a date, how do I get the last date of that month? I have data in the form YYYYMM, that I've read as a date using > x$Date <- as.Date(ISOdate(substr(x$YearEnd,1,4),substr(x$YearEnd,5,6),1)) But this gives the first day of the month. To get the last day of the month, I tried > as.Date(as.yearmon(x$Date,frac=0)) But I don't get the last day of the month here. (Tried

Folks, I have a data frame with columns 200401, 200402, ..., 201207, 201208. These represent years/months. What would be the best way to sum these columns by year? What about by quarter? Thanks for your time, KW -- [[alternative HTML version deleted]]

The command below was run on FreeBSD 7.2 with rsync-3.0.3. The command works but copies all files, i.e. no hard links created. rsync -vaxH --numeric-ids --delete --exclude=/home/apache/logs \ --link-dest=/mnt/200912/newharbor/home -e ssh newharbor.safeport.com:/home \ 201001/newharbor/home/ The command was run without the continuation breaks that I added for readability. The command

Dear R experts, I have a dataframe imported from a csv file (with read.csv). Here is an example: yyyymm<- c("19860228", "19860331","19860430","19860531") id<-c("10000","10000","10000","10000") re<- c("C","0.25", "0.98", "1.34") mret<-data.frame(yyyymm, id, re)

I need to merge three datasets and don't know how. If I were using SQL, I would use df3, look up the characteristics of each date in df1 and the value for each observation in df2. df1 - unique list of Dates and characteristics of those dates Date, YYYYMM, YYYYWW, DOW df2 - the raw data Date, Place, Value df3 - all posibile combinations of Date + Place (via

Dear anyone who knows more about R than me (so everyone). I have been bashing my head on the keyboard all day trying to do something with my table. I have some data, like so: yyyy-mm Rainfall(mm) 1 1977-02 17.4 2 1977-03 34.0 3 1977-04 26.2 4 1977-05 42.6 5 1977-06 58.6 6 1977-07 23.2 7 1977-08 26.8 8 1977-09 48.4 9

Hi, While doing Linux kernel builds linked with lld, I've tracked down a difference that breaks relocation of the kernel image (e.g. under KASLR[1]). Some relocations are changed to ABS (weirdly, all are in .rodata section). Note the difference below in the resulting linked output. .L__const._start.instance becomes *ABS* only under lld: $ cat minimal.c struct minimal { void *pointer;

Dear R experts, For quite some time I have been trying to solve a mistery of reading a seemingly trouble-free text file. The data is temperature reconstruction arranged as a huge grid, preceded by seven "header lines" (which you see better if file is opened in Firefox or Chrome). This is the data (gridded temperature reconstruction)

hi chaps: apologies, more naive beginner's questions. my data sets contain multiple time series and look like date x y 196211 12 1 196212 4 2 196301 44 5 so dataset <- read.table("data.dat", header=T); works well enough. tsdataset<- ts(dataset, freq=12, start=c(1962,11)) also seems to work. summary(tsdataset) and print(tsdataset) show that this

Hi, I am trying to create a googleVis motion chart with monthly data. When formatting the date column as a Date class variable, the plot as presented in the browser becomes considerably slower and very prone to crashing the browser. To illustrate this issue I have modified the WorldBank demo. ### objects from demo("WorldBank", package = "googleVis") M <-

Hello, For basic date time arithmetics operations, AFAK, there're actually the function difftime() and the (dt + num) operations. I'm wondering if other basic operations exist, like add(dt, num, unit) where unit would be "y", "q", "m", etc. Also for the function seq.dates (or seq.POSIXt), the case for by="months" would be more useful if it

Hi all, I am wondering how to write a 'list' object to a file. I already gone through some threads like http://mail.python.org/pipermail/python-list/2001-April/080639.html, however could not trace out any reliable solution. I tried following : > write.table(calc, file="c:/data.csv") Error in data.frame("200501" = c(-0.000387071806652095, -0.000387221689252648, :
