Hi, I would appreciate if someone can give me a pointer on how to save a webpage programmatically using R. For example, let say I have this webpage open in my browser: http://www.bseindia.com/stock-share-price/dabur-india-ltd/dabur/500096/ When manually I save this page, I just press Command+S (using Mac) and then this page get saved in hard-disk Now I want R to mimic this same job that I do

See, I have built my own genetic algorithm already and tested it on this problem. I have a solution, but due to the heuristic nature of GA, I cannot guarantee that it is the optimal subset. If I was simply doing this for a company project, you are spot on with the type of algorithm I would use, but I am doing this for a scientific paper. I need to be able to find the optimal subset over my

I am looking for packages that can run a branch-and-bound algorithm to maximize a distance measure (such as Bhattacharyya or Mahalanobis) on a set of features. I would like this to be learning algorithm independent, so that the method just looks at the features, and selects the subset of a user-defined size that maximizes a distance criteria such as those stated above. Can anyone give some

There is also the package solrad that might do some of this. It is more intended for calculating solar radiation, which is probably not what you want, but may do other things you may find helpful. > On Jan 30, 2024, at 5:44?AM, Enrico Schumann <es at enricoschumann.net> wrote: > > On Tue, 30 Jan 2024, Richard O'Keefe writes: > >> Given >> - UTC timestamp

Dear All, My query is: Do we always need to use perl = TRUE option when doing ignore.case=TRUE?

In the first paragraph of Sweave.Rnw (./src/library/utils/vignettes/Sweave.Rnw), it reads for literate programming \cite{fla:Knuth:1984}. but probably should be for literate programming \citep{fla:Knuth:1984}. ^ kind regards Enrico -- Enrico Schumann Lucerne, Switzerland http://enricoschumann.net

Thanks for your pointer. Is there any way in R how to replace " ' " with " /' " programmatically? My actual string is quite lengthy, so changing it manually may not be possible. I am aware of gsub() function, however not sure I can apply it directly on my original string. Regards, On Tue, Jul 18, 2017 at 10:27 PM, John McKown <john.archie.mckown at gmail.com>

Hi I have "observations" obs <- (11455, 11536, 11582, 11825, 11900, ...) and a simulation function f(A,B,C,D,E,F), so sim <- f(A,B,C,D,E,F) e.g. sim = c(11464, 11554, 11603, 11831, 11907, ...) now I would like to fit A,B,C,D,E,F such that "obs" and f(A,B,C,D,E,F) match as well as possible. A,..,F should be integers and have bounds. How would you solve this problem

Dear R contributors, I have a problem in selecting in an efficient way, rows of a data frame according to a condition, which is a part of a row name of the table. The data frame is made of 64 rows and 2 columns, but the row names are very long but I need to select them according to a small part of it and perform calculations on the subsets. This is the example: X Y "Unique to

I have a humongous csv file containing census data, far too big to read into RAM. I have been trying to extract individual columns from this file using the colbycol package. This works for certain subsets of the columns, but not for others. I have not yet been able to precisely identify the problem columns, as there are 731 columns and running colbycol on the file on my old slow machine takes

Dear All, I am using package fPortfolio to run minimum variance portfolio optimizations in R. I already know how to set portfolioSpecs, portfolio objects and constraints. Unfortunately I am not able to set the following type of constraints. I have a timeSeries object with returns data for roughly 1.5k assets for 261 subperiods (workingdays) and want to compute the global minimum variance

Hi again, Let say I have below string (arbitrary) <html> <head> <script type="text/javascript" <script type="text/javascript"> mystatement('current', {'pac':['']}); mystatement; I want to pass above string to some R variable for further analysis. So I have tried below : String = '<html>

It was suggested to quote your string with *backticks* (` ... `) rather than single quotes.
