Dear R-ers: I'm sorry to disturb you, I want just ask if R can plot a given complicated density function. I mean if we have the expression of the density en we want to see how it's look like? and this is a density with two variables thus it's a 3D plot Thank you very much Hicham Amsterdam

Dear R-ers: I'm sorry to disturb you, I want just ask how to export a data set (matrix) from the editor window of R to (for example) a txt if i type fix(data) i get a R editor window, I want to use this dat in other statistic program how i do that Thank you very much Hicham Amsterdam -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list --

hello I work on the probabilities of bivariate normal distribution. I need integrate  the following function. f (x, y) = exp [- (x ^ 2 + y ^ 2 + x * y)] with - ∞ ≤ x ≤ 7.44 and - ∞ ≤ y ≤ 1.44   , either software R or  matlab Version R 2009a Thank you for helping me Regards Mezouara hicham PhD in Metrology Hicham_dess @ yahoo.fr [[alternative HTML version deleted]]

Hello, I have used the univariate Ripley K function in R, but does anyone know if there is a bivariate function built in? I have two species that I am dealing with. Also, how might I add error bars into the graphs (univariate and/or bivariate)?

Dear Sir, I am beginner in using R. I am working on climate and like to plot spatial but I can't able to go ahead. I know it is too simply but not for me. Here is attached the data and my sample script. I am waiting R-users to solve my problem. Your help is valuable for me. Thank you. -- --------------------------------------------------- *Bedassa Regassa Cheneka* *Adama Science and

Ok, after several months of pulling my hair out I finally fixed WINS and browsing at out Univesity. It ended up being an acutal bug, er bad code segment. To explain we have a large number of clients ~1000+ at any one time over 6 subnets. Browsing was spuratic at best. nmbd sucked up %70 of the proccessing power of a sparc 5. Well after serious investigation I traced it down to two lines of

Dear sir, I would ask if there are in R some code to generate a random sample from a mvariate student distribution like that one wich generate the multivariate normal one i mean( rmvnorm(n, mu, sigma) Second question : if R can plot density 3Dcurve I don't mean de histogram but de hole density function(normal for example). I use a windows version of The R software Thank you in advance wiyh

I discover last week the R software statistics programm, I have a small questions, When we generate a bivariate normal distribution is it possible to plot the generate distribution. The second one if there is a code to generate a bivariate student distribution. If yes i would ask you gratefully a help. Thank you very much

Hi, Is the array mstats returned by virDomainMemoryStats call cummulative or snapshot of the counter at that particular time ? I was of the opinion that is cummulative like the /proc counters but this counter seems to go backwards ie next snapshot value is less than the current one which makes me think these are snapshot values . I'm using RHEL 6.3 libvirt version 0.9.10. Regards,

Dear R-Users, I'd like to have some tips for a ternaryplot ("vcd"). I have this dataframe: a<- c (0.1, 0.5, 0.5, 0.6, 0.2, 0, 0, 0.004166667, 0.45) b<- c (0.75,0.5,0,0.1,0.2,0.951612903,0.918103448,0.7875,0.45) c<- c (0.15,0,0.5,0.3,0.6,0.048387097,0.081896552,0.208333333,0.1) d<- c (500,2324.90,2551.44,1244.50, 551.22,-644.20,-377.17,-100, 2493.04)

Hi everyone, I'm working with Asterisk 1.4-beta3 and ARA for my Univesity thesis, to enable jingle support into an administrative framework for asterisk developed in our lab. It's possible to map jabber's and gtalk's user from the ARA database, as I have already done with sip and iax users? I need to know what family I must map to my database (such as iaxusers, sipusers... etc) to

We're running dovecot 2.3.10 on two different servers (two different environments). Both very similarly configured (sendmail and procmail for mail delivery); same OS and patch levels. One environment has nearly 10,000 users and hasn't seen problems. The other environment has just a handful of users, but one user is very active with email and has a fairly complicated procmail

Hi, I have some servers that are dedicated to do meetme conferencing. From some previous test i concluded that I need to use dahdi_dummy as it is more accurate. If I did use the core timers in dahdi (not loading dahdi_dummy) I got bad quality in the conferences and dahdi_test showed 99.6% as worst. I thought maybe the issue as bad hardware for the timing or something else. But today I

Hi, are there any function to plot the empirical probability distribution function? I just don't want to reinvent the wheel...

Dear R help gurus, I have the following problem and I would be delighted if you could help me. >From a large (1500) cohort of patients we have been taking some measurements (ECG measurements, but its not important). The measurements are ordinal in 4 grades (Grade I-IV, grade IV being the most severe form). Every patients has been measured several times (usually once per year). The

Hi, I was trying to draw an empirical distribution function with uniform confidence bands. So I tried to find a way to calculate values of the Kolmogorov-Smirnov Distribution but failed. I guess it must be hidden somewhere (since the ks-test is implemented), but I was unable to find it. Is there any way to do this? Thanks Leif Boysen

Colin, If your propose is to create a ternary plot with points and vectors, I think easier do this with graphics based plots instead of trellis based plots. Although, with little work you can do with trellis too. I gave you a reproducible code to put an arrow in a ternary plot. I use the function locator() to extract coordinates. The code is the following

Hi, I am sending my application I submitted for the GSoC.

Hi, all ecdf function (Empirical Cumulative Distribution Function) in "stats" package counts from smaller values to larger values. However, I want to draw it by counting from larger value to smaller values and I couldn't find options for this purpose. How can I draw ecdf or ecdf like graph by counting from larger values to smaller values. Thank you in advance. Hyunchul Kim
