Hi all, I am using RCurl to try and download data from a website, but I'm having trouble finding out what URL to use. Here is the site: http://www.invescopowershares.com/products/holdings.aspx?ticker=PGX See how in the upper right, above the displayed sheet, there's a link to download the data as a .csv file? When I hit "copy url" and paste into getURL in R, it doesn't

Hi all, I'm looking at a large data set, and I'm interested in removing rows where only one variable is duplicated. Here's an example: > presidents Qtr1 Qtr2 Qtr3 Qtr4 1945 NA 87 82 75 1946 63 50 43 32 1947 35 60 54 55 1948 36 39 NA NA 1949 69 57 57 51 1950 45 37 46 39 1951 36 24 32 23 1952 25 32 NA 32 1953 59

Hi all, I'm trying to write a function that will search and extract from a long character string, but with a twist: I want to use the characters before and the characters after what I want to extract as reference points. For example, say I'm working with data entries that looks like this: Drink=Coffee:Location=Office:Time=Morning:Market=Flat

Dear R People: Is there an R sig for Tcl/Tk, please? I looked at the User Groups list on the main page and didn't see one. However, I thought I'd double check.

Dear all, I'm trying to run function "qvalue" that requires Tcl/Tk interface. But after loaded the "tcltk" package, it would automatically launch "point-and-click" that forces me to run analysis in a new window whenever I want to use the function. I would be grateful if anyone knows how to remove the auto-launch operation in R so that I can run the function

Hi List, Is it possible to tell R to use tcl/tk 8.5? My R package seems to depend on libtcl8.4.so. However, in Windows it seems to be possible to set TCL_LIBRARY and MY_TCLTK. Is there something similar possible in Linux? I have installed: $ rpm -q R R-2.3.1-1.fc5 $ locate libtcl8 /usr/lib/libtcl8.4.so /usr/local/lib/libtcl8.5.so

Dear all, I'm using tcl/tk to create a program to get answers from the user. I'd like a way to highlight/emphasize some of the information using colors. It'll be even better if I can color part of the messages instead of the whole thing.

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags?
