Dear All, Reverting to RODBC 0.9.1 that I had archived resolved the problem. Thanks to Professor Ripley for noting that I had a non-release version of RODBC (how I might have obtained it is still beyond me...
Hi, The Omegahat site looks to be down (one could add "again" after a glance at the r-help history); does anyone have their RDCOMClient package, on which RBloomberg depends? I looked for mirrors, but the one's I've...
Professor Ripley, > There is no statement 3 in the released version of sqlGetResults ... In other words, I have an outdated/wrong version of RODBC? > You can. R are RODBC and Open Source, so why not open it and read it...
Dear all, How can one fit just a fixed effects model in R? lme() seems to require a random component, whereas I am just looking for something like STATA's "xtreg, fe" function. Thanks, Pijus ---- W: 212-588-7897 F...
>Suppose I have a vector >Fruits <- c('Apple','Orange','Pear','Banana','Mango') >I want to print the statement >"The fruits in the basket are: Apple, Orange, Pear, Banana, Mango" How about this: cat("The fruits in the basket are: ", paste...
Dear all, Currently, a ts object behaves like an array, and it would be very useful to have a similar object, which would behave like a data.frame, i.e. it could be indexed, named, etc. like a data.frame...
Dear all, My colleague, who has been helping me with wrapping some older C++ code for use in R, has been running into some issues, which he asked me to post here: - ERROR is defined in RS.h which is...
Joe, Others have already pointed out the available QP tools. Let me add that you can always just write down utility as a function of portfolio weights and use optim() to solve the Markowitz problem (and more). Cheers, -P -----Original...
Thank you. When I tried to set as.list() in baseenv(), I learned that its bindings are locked. Does this mean that the thing to do is just to write my own "lapply", which does the coercion using my "private...
Hi, I would like to get lapply() to work in the natural way on a class I've defined. As far as I can tell, lapply() needs the class to be coercible to a list. Even after I define as...
Dear all, I am just getting into R, and I arrive with a task in hand. I need to handle time series of price data, and use them in regressions and cluster models of various kinds. At this time, I...
Dear all, I've encountered a curious problem. I am trying to run an SQL query using sqlQuery() function in RODBC. The query works fine when run in a stand-alone SQL browser (Microsoft Query Analyzer, in particular). However, when...
Jay, Unless I am missing something that makes "scatter plot" graphs a particular term of art in finance, wouldn't the good old plot() function do all you require? As for "graphing R-squared", I am not quite sure what...
Much as I love R, I had occasion to contemplate its limitations vis-?-vis Python this weekend, when I had to scrape brutally malformed HTML and actually found it to be fairly painless thanks to BeautifulSoup (http://www.crummy.com...
Hoon, Your questions were addressed to David, but I hope he won't mind if I interject. "How to handle a large dataset" is practically a FAQ on the R-help list: search through the archives at http://maths.newcastle...
Dear Dirk, As far as my personal experience goes, I needed to estimate such models some time ago, when the R toolkit for this sort of thing was still almost empty, so I chose to invest in STATA: it provides...
