Hi I am just starting to look at R and trading in futures, stock, etc Can anyone point me to useful background material? Stephen Choularton 02 9999 2226 0413 545 182 -- 11:39 PM [[alternative HTML version deleted]]

Dear R-community, I am looking for some simple advice - I have a matrix (therefore 2 dimensional) of global temperature. Having read R-help I think that when I ask R to image() or levelplot() my matrix will it actually appear upside down - I think I therefore need to use the line: > levelplot(temperature.matrix[,ncol(output.temp):1], ........) to get it looking like it was on the globe due

Dear R-help community, I need to find out how to make the black axis line around my plot thicker in levelplot, I cannot find the correct command in ?levelplot or ?par - or if it is there I cannot get it to work - any help would be more that appreciated! Here's an example script - I would want the code for making the axis bordering the plot thicker: x<- seq(pi/4, 5*pi,length=100)

Dear R-help, I have a loop, which is set to take about 26 hours to run at the rate it's going - this is ridiculous and I really need your help to find a more efficient way of loading up my array gpcc.array: #My data is stored in a table format with all the data in one long column #running though every longitute, for every latitude, for every year. The #original data is sotred as

Dear R-help community, I have looked on the R search site and archives but cannot find mention of a way of interpolating a gaussian distribution of data to a standard 2.5 degree grid. I have two global dataset and I need to correlate - unfortunately one is a 2.5 degree grid dim[longitude=144,latitude=72] and one is gaussian dim[longitude=192,latitude=94]. I would rally appreciate hearing

What syntax is needed to make this work? The 2.0 wiki recomendations don't work - I can see the inboxes or the folders but not both at once and there are lots of error messages about prefix clashes if I simply use the existing 2.0.20 conf file on 2.1.6 The layout I have is: Inboxes in mbox format - /var/spool/mail/%u Folders in maildir format - /var/spool/imap/%u/Maildir/ Control and

Dear R-help, Which random number generator function would you recommend for simply picking 15 random numbers from the sequence 0-42? I want to use replacement (so that the same number could potentially be picked more than once). I have read the R-help archives and the statistics and computing book on modern Applied statistics with S but the advice seems to be for much form complicated

I want to get a sample of some arbitrary size from a population having only two values 0 and 1 with replacement, but with different probability for selection. For example 0 will be selected with probability 0.4 and 1 with 0.6. I could use sample function i.e. sample(c(0,1), 30, T) to get this, however here, selection of either 0 or 1 has equal probability here. I am looking for a function which

Dear R-help community, Does anybody know of a stats function in R that tells you which distribution best fits your data? I have tried look through the archives but have only found functions that tell you if it's normal or log etc. specifically - I am looking for a function that tells you (given a timeseries) what the distribution is. Any help/advice will be greatly appreciated, All the

Hi Jenny If you want a general solution I understand. However I just downloaded the file fine (as far as I can tell) so you are welcome to have a copy. I can email it to you if you want. I do not think your test for NA is valid. i.e if(test != "NA"){ } I think you should use if(is.na(test)){ } Or something similar. J --- John Seers Institute of Food Research Norwich

Dear R-Help community, I am trying to overlay a single contour line over a correlation plot using levelplot in the lattice package. These are the two arrays: 1) a correlation plot over Africa - so each grid square is a different colour dependent on correlation - this is in an array: result_cor with dim[465,465] 2) a single contour line from a ***different data source*** - this is from data

Hi all, I am also looking for interesting statistical experiments about testing and estimating CAPM, APT, Fama models, etc. using R using financial series data... please give me some pointers... I have been searching the R archives for the past a few hours and I vaguely got to know that there are programs do these interesting statistical things, but I just could not find where are they... I have

Dear R-Help, I am trying to find a function that will give me the significance of the correlation of 2 variables (in the same dimension arrays) correcting for serial autocorrelation. How can I view the function cor.test's code? I would like to know a lot more detail about the function than written in the documentation at http://finzi.psych.upenn.edu/R/library/stats/html/cor.test.html to

Dear R-Help friends, I am unable to get the latest version of R (2.4.1) to compile on my solaris 10 system - has anybody else experienced this problem and are you able to offer me any advice? I appreciate your time, many thanks, Jenny Barnes Here are my CURRENT specifications: platform sparc-sun-solaris2.10 arch sparc os solaris2.10

Every post I do to this mailinglist is followed by a bounce message from "centos.5.warren at recursor.net". I have no clue why this is being send to me, afaics some IP address is being blacklisted but I am not related to it. Am I the only one who gets this and can we remove this person from the mailinglist ? Kind regards, -- dag wieers, dag at wieers.com, http://dag.wieers.com/

I recently set up samba-2.2.3a on FreeBSD 4.5-RELEASE. I'm having troubles getting printing to work. I have LPRng-3.76 installed, and it works just fine using the command line tools. When I print from a windows client over smb, however, I can see the job go into the spool directory, but then it magically vanishes, with nothing in any log files. Has anyone experienced this type of strange

With the latest message I send to the CentOS list I got this strange 'probe' message. The included bounce example has nothing to do with my email-adres, but rather with someone subscribed to the list. So it seems that somehow the mailinglist manager is sending bounces to the wrong email-adres. Or I do not understand the 'probe' message (and the included bounce message) at all.

Dear R-help community I am trying to write an R object (data.out) to a file in order to re-access it later and not have to re-load up the array with data every time. Here is the form of data.out > data.out <- list(lats=seq(88.542, -88.542, length=94), lons=seq(0, 360-1.875, length=192), date=vector(length=nyr*12), data=array(NA, c(nyr*12, 94*192)) ) I tried >
