Dear all Is there any R function that would perform currency conversion using up-to-date exchange rates? I would be looking for a function that allows to download recent exchange rates (say, from Yahoo!) and then use these in converting currencies (say, USD to EUR). I am not sure whether r-sig-finance would be more appropriate, but the (off-)topic feels general enough to me. Thank you Liviu --

Dear sir, I am extremely sorry for messing up the logic asking for help w.r.t. my earlier mails   I have tried to explain below what I am looking for.     I have a database (say, currency_rates) storing datewise currency exchange rates with some base currency XYZ.   currency_rates <- data.frame(date = c("12/31/2010", "12/30/2010", "12/29/2010",

Is there a cost involved? I already have a brokerage, but can't get MetaTrader 4 through them.

I''m thinking of experimenting with some currency conversion. However, I''d like the conversions to be in synch with the current rates. Anyone know (and this maybe out in left field) if there is some online (perhaps xml) or other data stream I can connect with in my code to output values based on user selection ? TIA Stuart

Hello, I would like to get a window handle from another app outside of wxRuby and convert it into a wxRuby Window handle so that I can use it as the parent Window for several wxRuby child windows. Basically I want to use the FRAME_FLOAT_ON_PARENT window style so that my wxRuby windows become associated with the outside app kind of like toolbars, e.g., they don''t show up in the

Hello, After reading help file, various threads on this board, and other online tutorials, I've attempted to use gsub (using Perl-like syntax) to change a currency string into something that can be converted to numeric type using only one regular expression.  Can anybody point out my error?  Note that >  x <- "\"$ 1,200,300,400.50\"" Tried the following in an

I'm struggling to find any help on this seemingly simple question - how does one read data with percentage (%) or currency (?,$ etc.) signs? When I try to read a data file which has any of those symbols in the data fields, they are read as characters rather than values. Is there a function or library which can deal with such values? As an example, I use this sample from one of chinna's

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where

Hi, I''m interested in using a currency conversion web service in my rails app. Does anyone have a free service that they use and like? I found this one http://www.webservicex.net/WS/WSDetails.aspx?CATID=2&WSID=10 I''ve tried to make a simple, plain Ruby script to connect to this and get a conversion rate without success. How do I integrate a webservice into my rails app? I

My mistake sir. I was literally engrossed in my stupid logic, and while doing so, overlooked the simple and very effective solution you had offered.

I was on vacation the last week and wrote some code to run a 500-day correlation between the Nasdaq tracking stock (QQQ) and 191 currency pairs for 500 days. The initial run took 9 hours(!) and I'd like to make it faster. So, I'm including my code below, in hopes that somebody will be able to figure out how to make it faster, either through parallelisation, or by making changes. I've

How do you label Xtick and Ytick marks with Currency symbols: $2000 instead of 2000? I would like to add dollar symbols to tickmarks on boxplots, histograms and back-to-back histograms.

1) A user enters $100 into a textfield and submits, I need to strip off the $ sign before it gets saved to the db. 2) The name of the field is "price", why does params[:price] upon submitting have nil value? -- Posted via http://www.ruby-forum.com/.
