Hey Everyone, I have been stumped by this all day. Basically, I have a data.frame of multiple columns. Of concern are "id" & "date" For some reason, oftentimes there are duplicates of data with the same date. I would like to remove the duplicates per different id (removing duplicate dates for the entire data.frame would leave nothing since different id's all have

I want to get data for a set of ticker symbols and compute the daily return of the adjusted close using quantmod, and then scatterplot returns using pairs(). The following gets data for the list of tickers: tickers <- c("SHY","TLT","SPY","IWM","GLD","IEV","ILF","EWJ","EPP","SAF","ASA")

Dear R users, I am trying to use tseries' garch function in order to determine the volatility of a return series generated by quantmod. Here is the code that I am using: > library(quantmod) > getSymbols("AAPL") convert daily closing prices into continuous log returns > dret<-dailyReturn(AAPL,type='log') check to see that the autocorrelations decay >

I have two datasets, big and small. s_date<-c(?2005-12-02?, ?2005-12-01?, ?2004-11-02?,?2002-10-05?,?2000-12-15?) s_id<-c(?a?,?a?,?b?,?c?,?d?) b_date<- c(?2005-12-31?, ?2005-12-31?, ?2004-12-31?,?2002-10-05?,?2001-10-31?,?1999-12-31?) b_id<-c(?a?,?b?,?c?,?d?,?e?,?c?) small<-data.frame(date_=as.Date(s_date),id=s_id) big<-data.frame(date_=as.Date(b_date),id=b_id) For each row

I am running R 2.1.1 in a Microsoft Windows XP environment. I have a matrix with three vectors (“columns”) and ~2 million “rows”. The three vectors are date_, id, and price. The data is ordered (sorted) by code and date_. (The matrix contains daily prices for several thousand stocks, and has ~2 million “rows”. If a stock did not trade on a particular date, its price is set to “NA”)

Within an R dataset, I have a date field called “date_”. (The dates are in the format “YYYY-MM-DD”, e.g. “1995-12-01”.) How can I add or subtract “1 month” from this date, to get “1996-01-01” or “ “1995-11-01”. --------------------------------- [[alternative HTML version deleted]]

Hello, I have the data whcih are not balanced (several missing observations), and one possibility is t use interpolation method to get the information missing in this series from other series. Does anybody know how I can program interpolation of series1 (which ahs missing observations) and series 2-6, for example. Thanks a lot in advance, Silke

I''m doing some incremental improvements on scaffolding, and want to add in-place editing to an admin section. I think I may have the view part working right (at least, the editor pops up as expected) with this in my view: ### <% for link in @links %> <tr> <td> <div id="<%= ''url'' + link.id.to_s -%>"><%= link.url

Greetings, I am in the process of replacing my MicroFocus (Novell) eDirectory system with a Samba-based Active Directory system. I've got three domain controllers built, and they seem to be humming along nicely. Server OS is Ubuntu 18.04 patched current. I started off with the Samba 4.7 packages included in the default Ubuntu repository, but have since upgraded to Samba 4.10 using packages

Hi, we use OpenSSH_3.8.1p1 and we would like to change the complete printer Spool communication from Unix r-Commands to ssh "OpenSSH". Sometimes, we have problems, because of very high connection set-ups in extremely short time intervals, more than 10 open sessions. The connection set-up is partly declined with the error message: ssh_exchange_identification: Connection closed by remote

I really don't understand this... Virtually *none* of the other email lists I am on send all of the messages as separate attachments - they are forwarded inline. The only other ones that do this are the Openoffice.org lists, and I have the same problem with them. I use Thunderbird, which shows the attachments at the bottom of the window pane (this is not an option), and does *not* allow
