Hi, I have a dataset (CSV) with some counts of firms located around the globe. Each count is assigned to the longitude and latitude of the specific location. Now I want to plot these counts on a world map using dots (size of dots represent the count). I have been unable to find any info on whether this is possible and if so, how? Can you please help me? Thanks! Mathijs -- View this message

Hello, I have uploaded a csv file that looks like this: > gc alpha_id beta_id 1 142053 1 2 9454 1 3 295618 2 4 42691 2 5 389224 3 6 9455 3 The alpha_id contains 310660 unique values and the beta_id contains 17431 unique values. The number of rows adds up to more than 1.3 million. Now I want to convert

Hi, I have a series of MS word files and each file contains plain text. From these texts I would like to extract only those elements (read: words) that are between square brackets. Example of a text: Most fundamentally, it has led to an effort to clarify the organizational form concept. According to them [see also Smith, Jones and Carroll 2002], categories emerge as audience members recognize

Hi all, It looks like Dovecot 1.0rc7 reports the wrong content-type for messages with only a text/html body. An example of such a message is: --- From: mathijs at izecom.com Subject: test To: foobar at example.com Content-Type: text/html; test --- When I talk IMAP to Dovecot directly using telnet and fetch the bodystructure of this message, Dovecot replies: * 1 FETCH (BODYSTRUCTURE

I have a question about the Reduce function: x <- list() x[[1]] <- LETTERS[1:5] x[[2]] <- LETTERS[11:15] Reduce(paste, x) [1] "A K" "B L" "C M" "D N" "E O" How do I get this?: [1] "A" "K" [2] "B" "L" [3] "C" "M" [4] "D" "N" [5] "E" "O"

Hi, I have a postgresql and a mysql database and I would like to combine the info from two different tables in R. Both databases contain a table with three columns: project_name, release_id and release_date. So each project output could be released multiple times (I am interested in the first release_date). However, some of the data is missing. Basically, what I want to do is to try and fill the

Hi, I am running the following script for a different (much larger data frame): DF = data.frame(read.table(textConnection(" A B C D E 1 1 a 1999 1 0 2 1 b 1999 0 1 3 1 c 1999 0 1 4 1 d 1999 1 0 5 2 c 2001 1 0 6 2 d 2001 0 1 7 3 a 2004 0 1 8 3 b 2004 0 1 9 3 d 2004 0 1 10 4 b 2001 1 0 11 4 c 2001 1 0 12 4 d 2001 0

Hi, I have a FXImageFrame widget and I would like it to show another image when I click on it. I''m having no luck with receiving a onclick via SEL_LEFTBUTTONRELEASE. ... imageframe=FXImageFrame.new(mainwindow,the_image,LAYOUT_EXPLICIT,0,0,20,20) imageframe.connect(SEL_LEFTBUTTONRELEASE) {p ''onclick received''} ... What is it that I''m missing?

Hi, This is probably an easy one, but I am new to ggplot2 and cannot find an answer online. I am bar plotting values of 10 groups. These values are all within a 90-100 range, so I would like leave out the area of the bars below 90. If I say "graph + scale_y_continuous(limit=c(90, 100))", it does limit the axis but the bars disappear completely. Any solution here? Thanks a lot!

Hi, I know this question has come up before, but I couldn''t find a satisfying answer. Maybe I didn''t look well enough, so any pointers to old messages regarding this subject would be welcome too. I need some way to pass multiple ids to a resource. Something like /posts/13,14 If I do this I have to manually split the id on ","s in the action, and use post_path([post1,

Hi all, I think CSFR protection broke in rails 2.3.11. As in: it''s turned off now. I tried this in rails 2.3.10 and in 2.3.11 and 2.3.11 seems broken. >rails csrftest >cd csrftest >script/generate scaffold post title:string >rake db:migrate now I visit /posts/new in my browser, use firebug to delete or change the authenticity token, and submit the form. rails 2.3.11: all

First, the reproducable example, showing how converting from character to POSIXct to character changes the milliseconds in the first time stamp though not in the second: > as.POSIXct('2010-06-03 9:03:58.324') [1] "2010-06-03 09:03:58.323 PDT" > as.POSIXct('2010-06-03 9:03:58.325') [1] "2010-06-03 09:03:58.325 PDT" This seems to be due to truncation of

Folks, I've run into trouble while writing functions that I hope will create and modify a dataframe or two. To that end I've written a toy function that simply sets a couple of variables (well, tries but fails). Searching the archives, Thomas Lumley recently explained the <<- operator, showing that it was necessary for x and y to exist prior to the function call, but I haven't

I can use data() to find the available datasets in a package, but I'd like to extract and display some additional information for each dataset than what is provided by data(), e.g., class() and dim() for datasets for which these are available. I'm stuck on using using lapply properly with objects, rather than the names of objects that I get from data() Example: > DS <-

I know R has a steep learning curve, but from where I stand the slope looks like a sheer cliff. I'm pawing through the available docs and have come across examples which come close to what I want but are proving difficult for me to modify for my use. Calculating simple group means is fairly straight forward: data(PlantGrowth) attach(PlantGrowth) stack(mean(unstack(PlantGrowth)))

Hi, I need to perform calculations on subsets of a data frame: DF = data.frame(read.table(textConnection(" A B C D E F 1 a 1995 0 4 1 2 a 1997 1 1 3 3 b 1995 3 7 0 4 b 1996 1 2 3 5 b 1997 1 2 3 6 b 1998 6 0 0 7 b 1999 3 7 0 8 c 1997 1 2 3 9 c 1998 1 2 3 10 c 1999 6 0 0 11 d 1999 3 7 0 12 e 1995 1 2 3 13 e 1998 1 2 3 14 e 1999 6

Hi list, Can anyone tell my why the following does not work? Thanks a lot! Your help is very much appreciated.

Folks, I've been running into an odd situation that occurs when I use length() function with aggregate(), but not with either one separately. Together, the results looks correct but is given an unexpected name. 'if (stringsAsFactors) factor(x) else x' instead of just 'x'. # Numbers work ok tt <- data.frame(idx=c(1,1,1,1,1,1,2,2,2,2,2,2)

Folks, Updating values in a table is simple in SAS or SQL, but I've wracked my brain looking for an elegant solution in R to no avail thus far. Certainly this is a common need that's been solved in dozens of different ways. Given an initial dataframe nn and a smaller dataframe of updates uu, I'd like to replace the values in nn <- expand.grid('a'=1:4, 'b'=1:3)
