I have a four-digit string I want to convert to five digits. Take the following frame: zip 2108 60321 60321 22030 91910 I need row 1 to read '02108'. This forum directed me to formatC previously (thanks!) That usually works but, for some reason, it's not in this instance. Neither of the syntaxes below change '2108' to '02108.' The values in cand_receipts[,1] are of

Dear expeRts, I have two matrices A and B. They have the same number of columns but possibly different number of rows. I would like to compare each row of A with each row of B and check whether all entries in a row of A are less than or equal to all entries in a row of B. Here is a minimal working example: A <- rbind(matrix(1:4, ncol=2, byrow=TRUE), c(6, 2)) # (3, 2) matrix B <-

Hi - First post, so excuse any errors in protocol: Wanted to ask if there's an easy way to use 'predict' with objects of class 'censReg', 'maxLik', 'maxim' or 'list'. Have a left-censored dataset, attempting to use a Tobit model and am working with the censReg package. I like how easy it is to move from glm models to predictions with

I'm sure this is smack-head moment, but I haven't been able to find an example of this on Nabble or SO, so thought I'd ask. This works: michigan <- map_data('county', 'michigan') mich_points <- data.frame(x = rnorm(n = 200, median(michigan[,1]), 0.75), y = rnorm(n = 200, median(michigan[,2]), 0.75)) ggplot() + geom_path(aes(long, lat, group = group), data =

I'm sure there's a better way to do this using plyr. I just can't nail the right series of commands. I've got a vector of strings. I want to remove all where the string's count within the vector is > 1. Right now I'm using: Where x2 is the original data.frame and my character strings live in x2[,3]. Based on my results, that looks like it works, though if someone

Working code that normalize each row's value against the subset's maximum. Does the invocation of max() somehow instruct R to 'step back' and evaluate the subset?

json_dir is a list of JSON lists mapping lat/long route points between locations using CloudMade's API. post_url is the URL of the HTTP request for (n in json_dir) { i = i + 1 if (typeof(json_dir[[i]]) != "NULL") { if (i == 1) { dat_add <- ldply(json_dir[[i]], function(x) t(data.frame(x)), .progress = "text")

I got a problem with UL followed by by OL when I using perl module "Text-Markdown-1.0.5".

Hi, Given a function fun <- function(a, b) a + b how do I generate the function 'function(x, y) x + y'? Working from the help files and Bill Venables' R-news article (June 2002), I have tried various permutations with substitute without success. e.g. do.call("substitute", list(fun, list(a = as.name("x"), b = as.name("y")))) Regards, John.

Hello, I am running dovecot 2.2.34 (874deae), on Debian stable, from backports.

I thought I had this nailed but.. now I''m seeing spots.. I''ve included my models below, feel free to ignore them. I''m really just after an example that works. I couldnt find one on the wiki... which is fair enough considering Ricks patch: http://dev.rubyonrails.org/changeset/4022 that fixed them only went through 5 days ago.. Cheers -henster

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''

Hi, I have a basic question about aligning date labels for the x-axis in an xyplot so that they align with the grid lines from the panel.grid argument. For example, with x <- data.frame( date = seq(as.Date("2005/01/01"), as.Date("2006/06/01"), length.out = 20), value = runif(20)) xyplot(value ~ date, data = x, panel = function(x, y, subscripts, ...) {
