similar to: help with loop over data frame

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 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

Hi all, Please forgive this newbie posting to the list for the first time if I haven't followed proper procedure. I have read through many of the archives and find them most useful in learning R. I have ten years daily data (stock closing prices) which I read in zoo format. I am having problems coding R to run a count of how many days in each month have a price higher than the first day

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, 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).

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, 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-Helpers: I?m trying to use the function GLMM from lme4 package, (R-1.8.1, Windows 98),and I get the following error: > pd5 = GLMM(nplant~sitio+ + fert+ + remo+ + sitio:fert+ + remo:sitio+ + remo:fert+ + remo:fert:sitio + data=datos, + family=binomial, +

Hi there Looking at the archives I didn't find a solution to the following problem we have here: Printing from our linux-server (wagner) to an intel printserver (PS652D8F) doesn't work.

But I figured that if the guy didn''t know what a switch was, a vlan would just further confuse him.

Hi, I'm using zoo because it can automatically label the months of a time series composed of daily observations. This works well for certain time series lengths, but not for others, e.g.: While: > library(zoo) > plot(zoo(runif(10), as.Date("2005-06-01") + 0:50)) Shows up the months and day of month, > plot(zoo(runif(10), as.Date("2005-06-01") + 0:380))

Hi, I'm using a ZaptelBRI card. It works fine. But I have a small problem with call logs. The leading zeroes of the external calling party are not stored (e.g. : 0140302010 will be stored as 140302010). Same for international numbers for which "00" will be stripped out. I would not mind if the cdr record would give me an indication of the call's origin (national or
