hi meeryana, may be this time nobnody is responding. but dont worry you will get a lot of help eventually, so always post a copy to the mailing list. The reason is there are a lot many newbies, although i am also not so old enough, who have even the simplest questions but are hesitant to ask. the objective of the list is to help, and thus feel free to ask, stand and contribute :-) i hope you will understand not today then tomorrow as you will get associated with the mailing list more closely. Personally i have found friends here. Further, never post a mail with a loose subject and secondly try to maintain the thread i.e. reply to the mail which you want to reply(for more details refer to the posting guide) :-) that would really help.
Yes now regarding your question :-) Step1 : List of all packages can be found at this link :-) http://cran.r-project.org/src/contrib/PACKAGES.html Step2: Click on the package you want to install :-) http://cran.r-project.org/src/contrib/Descriptions/copula.html Step3: Then download the binary of your Operating system. If windows then download corresponding zip file. for copula it is http://cran.r-project.org/bin/windows/contrib/r-release/copula_0.5-3.zip save zip file on your system Step4 Open your R rpogram Step5: Goto Packages -> Install packages from Local Zip file Step6: Select your package zip file which you want to install Step7: Sit back and relax Step8: load the library using library(LibraryName) on R prompt There are alternate ways of installing the package directly from R prompt. It didn't worked for me a long time back, so i always adopt this method. Somebody on the list may help you in this regards :-) bye and learn Join and stand with Open Source and R community Cheers and Chiao, Welcome -gaurav dear Mr. Yadav, I want to thank for help, and for that you are only who is willing to help, but I have one question: because I'm new with R project also, I think I should install a package for copula. I have only installed R program. How should I install this package? And is it what I have also to do with credit metrics, Value at Risk, matix and the other formulas, I mean install packages. I hope that you have a little time for me and my problem, and I hope I'm not disturbing you. thank you for all you can do for me and best regards, Mirjana gyadav wrote: > > > hi > > see the code below i hope this will make your understanding of copulas > better > this code plots two normal distribution and their joint distribution > N[0,2] & N[0,4] > > HTH > > ######################code################################ > library("copula") > ###################copy in two parts in R################# > > ##################PART A################################## > ## construct a bivariate distribution whose marginals > ## are normal and Normal respectively, coupled > ## together via a normal copula > op <- par(mfrow = c(2, 2), # 2 x 2 pictures on one plot > pty = "s") # square plotting region, > # independent of device size > > x <- mvdc(normalCopula(0.75), c("norm", "norm"), > list(list(mean = 0, sd =2),list(mean = 0, sd =4))) > x.samp <- rmvdc(x, 10000) > par(mfrow=c(2,3)) > hist(x.samp[,1],xlab="Normal") > hist(x.samp[,2],xlab="Normal") > plot(x.samp[,2],x.samp[,1],pch=21,xlab="Normal",ylab="Normal") > > plot(dmvdc(x, x.samp)) > plot(pmvdc(x, x.samp)) > > ## At end of plotting, reset to previous settings: > > > ###########################PART B####################### > par(op) > for (i in seq(1:360)){ > persp(x, dmvdc, xlim = c(-4, 4), ylim=c(0, 1),theta=i) > } > > > Regards, > > Gaurav Yadav > +++++++++++ > Assistant Manager, CCIL, Mumbai (India) > Mob: +919821286118 Email: [EMAIL PROTECTED] > Bhagavad Gita: Man is made by his Belief, as He believes, so He is > > > > copula <[EMAIL PROTECTED]> > Sent by: [EMAIL PROTECTED] > 07/17/2007 12:53 PM > > To > r-help@stat.math.ethz.ch > cc > > Subject > Re: [R] R and Copula > > > > > > > > it would be great when somebody will help me > thanks > > > copula wrote: >> >> hi, >> first I want to say that I'm new here, and new with copula and R. >> >> That is the reason why I'm writing, if somebody can help me. >> >> I have to make an example of Copula. >> On internet I've found this forum and that copula can calculate with R. >> >> Can somebody help me with the thing how can I start and where can read >> about these stuffs. >> >> Thank to all who can help! >> >> >> >> > > -- > View this message in context: > http://www.nabble.com/R-and-Copula-tf4085867.html#a11644534 > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > > > > ============================================================================================ > DISCLAIMER AND CONFIDENTIALITY CAUTION:\ \ This message and ...{{dropped}} > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > > Quoted from: http://www.nabble.com/R-and-Copula-tf4085867.html#a11645614 ============================================================================================ DISCLAIMER AND CONFIDENTIALITY CAUTION:\ \ This message and ...{{dropped}} ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
