similar to: using zoo for daily stock prices

Is there a way of aggregating 'zoo' daily data according to day of week? eg all Thursdays I came across the 'nextfri' function in the documentation but am unsure how to change this so any day of week can be aggregated. I have used POSIX to arrange the data (not as 'zoo' series) according to day of week, but am curious if I've missed if a similar option available

Dear R-experts, Sorry if I've overlooked a simple solution here. I have calculated a proportion of the number of observations which meet a criteria, applied to five years of data. How can I break down this proportion statistic for each year? For example (data in zoo format): open high low close hc lc 2004-12-29 4135 4135 4106 4116 8 -21 2004-12-30 4120 4131

Dear List, Sorry if I'm overlooking something simple here but I have gotten a bit tangled. I am trying to print the next five values(with their dates), which occur after a certain condition is met. I have a series of data in zoo format, call it "A". From this series I have created a subset (also in zoo format) based on a certain condition, call this series "B". I

Hi R-experts, Thanks very much to Jim Holtman and Gabor on my previous question. I am having another problem with data manipulation in zoo. The following is data (Z) for first business day of every month in zoo format. I am trying to get mean of "open" for each year. I subset Z <- Z[,2] then > sapply(split(Z, format(index(Z), "%Y")),mean) I get error message:

Hi R-experts, I have a data frame (A) , and a subset (B) of this data frame. I am trying to create a new data frame which gives me all the rows of B, plus the 5th next row(occuring in A). I have used the below code, but it gives me all 5 rows after the matching row. I only want the 5th. FiveDaysLater <- A[c(sapply(match(rownames(B),rownames(A)), seq, length=6))),] Any guidance much

Dear List, Thanks to those who helped with my enquiry a few days ago. I have a another question on loops, in this case I am trying to print out the row of a data frame if the previous 3 values (daily values) in col5 are in descending order. I have this loop which works, but ask whether this can be done differently (without conventional loop) in R: flag="T" d= 3 # d represents

Dear List, Thankyou to Jim and Marc for their help on my previous question. I have a data frame of five columns, the first being a list of dates and the other four columns are numeric values. I wanted to list the days where all 4 columns of values are less than in the previous row. I used the following which works fine, except it doesnt show the dates for each row (the values from column 1).

Dear List, This may be the fifth time Ive tried to send this to the list so apologies if there are multiple emails. I need some help getting started with this problem. I have a data frame containing a year of daily stock prices in the following format: Date Open High Low Close 1/15/2000 10 11 8 10 1/16/2000 12 12 10 11 etc.. I want to create a new

If this is a new setup. And if this reflex your primary dns domain for your AD-DC. realm = EXAMPLE.COM Then i hope your really good with DNS setups, to easy to make errors here. Cannot contact any KDC for realm can be one of them. My advice use something like : realm = INTERNAL.EXAMPLE.COM Greetz, Louis > -----Oorspronkelijk bericht----- > Van: samba

Hello Samba Community, I would like to seek advice as my Samba AD tends to consume high memory usage caused by KDC service. This issue will always come back within a couple of days after I restart samba-ad-dc service. It does not help by increasing memory. >From message log: kernel: Out of memory: Kill process 14527 (samba) score 873 or sacrifice child Identified pid 14527 belongs to

Hi all, I have estimated a random panel model using plm function. I have a question about the vector of resduals obtained with the object $residuals. example: data("Produc", package = "plm") zz <- plm(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp, model="random", data = Produc, index = c("state","year")) res<-zz$residuals #

To all: I'm using RBloomberg to pull historical equity prices across a range of international markets. Bloomberg defaults to returning stock prices to R in local currency, for example, blpGetData(conn, "ALUA AR Equity", "PX_LAST",start="09/30/08", end="09/30/08") returns a stock price in Argentine Peso's. If ones use the BLPH function directly

I am currently trying to find MLE of a function with four parameters. My codes run well but i don't get the results. I get the following message: BHHH maximisation Number of iterations: 0 Return code: 100 Initial value out of range. I don't know this is so because of the way i have written my loglikelihood or what. The loglikelihood LogLik<-function(param){ beta_1<-param[1]

Hi, I am new to this list as a poster, but a reader for some time. I've using R for several weeks now, and I have a lot of questions about certain procedures. Here I go: I want to test if there are differences in the time spent by pollinators visiting flowers of a given plant species, according to a number of experimental manipulations made on those flowers.
