Calculate x-values from a spline
Hello, I calculate splines from messured points(x,y) of an unknown function f(x). e.g. x <- c(0.004115, 0.012345, 0.037037, 0.111110, 0.333330, 1.000000) y <- c(37, 50, 45, 60, 50, 66) w <- c(0.8540541, 0.8320000, 0.8822222, 0.7983333, 0.8220000, 0.8151515) as weights f <- smooth.spline(x,y,w) Now I have y-values and want to calculate the x-value(s) from this spline. There is no

Yearly statistics
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

aggregating data with Zoo
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

using zoo for daily stock prices
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

extracting data from zoo series
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

Is there better alternative to this loop?
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

aggregate in zoo
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:

how to show date with this subset
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).

Plotting three time series on the same graph
Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000. How can I display the tick marks for both on the left hand side without superimposing them, i.e. one set of tick marks in black right

What is the best way to have "R" output tables in an MS Word format?
Dear "R" list, Our statisticians usually give us results back in a PDF format. I would like to be able to copy and past tables from "R" output directly into a Microsoft Word table since this will save us tons of time, be more accurate to minimize human copying errors and help us update data in our papers more easily. Do people have suggestions for the best way to do this? I

ProPolice/SSP in 7.0
Hi there, I'm still running 6.2 on various servers without any tweaks (GENERIC kernel, binary updates via freebsd-update etc.) but lots of ports (apache, postgresql, diablo-jdk etc.) and would like to use stack smashing protection in order to harden my boxes and avoid many potential exploits. I've known about ProPolice/SSP for a while now (from the Gentoo world) and am aware that

I have upgraded on my debian server from samba 2.2.3 (stable ) to samba 3.0rc4 (unstable). The only problem that I have on my PDC is that italian character as ? (a') ? (u') etc. are non treated as they should and this can cause profiles non to load correctly. What should I do? THX Davide Parise E-Mail: d.parise@iskranet.it Cel.: +39 3333063640 FAX: +39 06233241981

Multiple Instancies of Samba on a single System
Hi out there, i intend to run multiple Instancies of Samba on a single, multi-homed, server, with each instance bound to a specific (logical) interface. If this works, it would be fine to me. Mainly for administrative Reasons. (You won't believe, but from time to time it becomes necessary to restart some services, but restarting the entire server is a real mess) Well here my

Group policies and Vista
Hi, coming back to my old topic: How to manage clients. Up to Windows XP one could use the NT4-style policies, but Vista does not seem to obey them. Are there any plans to get group policy functions on a samba-only domain? Or are there other ways to manage the clients? best regards, Gunther

Density estimation
Hi, I am analysing a dataset containing genetic distances within and between species. I want to show a overlap of the distributions of the intra- and interspecific values; on a second graph I use a cut-off value to determine these boundaries. As the dataset contains >30 000 values, I would like to do this with a simple line rather than superimposed histograms. Hence, density plots. With
