similar to: "reverse truncate" to extract only decimal values

I am trying to set up a function which processes my data according to the following rules: 1. if (x[i]==0) NA 2. if (x[i]>0) log(x[i]/(number of consecutive zeros immediately preceding it +1)) The data this will apply to include a variety of whole numbers not limited to 1 & 0, a number of which may appear consecutively and not separated by zeros. Below is an example with a detailed

I have numerous objects, each containing continuous data representing the same variable, movement rate, yet each having a different number of rows. e.g. d1<-as.matrix(rnorm(5)) d2<-as.matrix(rnorm(3)) d3<-as.matrix(rnorm(6)) How can I merge these three columns side-by-side in order to create a table regardless of the difference in length? I wish to analyze the output in a spreadsheet

Hi there, I'm dealing with a pretty big dataset (~22,000 entries) with numerous entries for every day over a period of several years. I have a column "judy" (for Julian Day) with 0 beginning on Jan. 1st of every new year (I want to compare tendencies between years). However, in order to control for a leap year (2004), I simply need to subtract 1 from every judy value for the year

Is there any way to identify or infer the inflection points in a smooth spline object? I am doing a comparison of various methods of time-series analysis (polynomial regression, spline smoothing, recursive partitioning) and I am specifically interested in obtaining the julian dates associated with the inflection points inferred by the various models. Tyler e.g.

http://www.nabble.com/file/p18018170/subdata.csv subdata.csv I've attached 100 rows of a data frame I am working with. I have one factor, id, with 27 levels. There are two columns of reference data, x and y (UTM coordinates), one column "date" in POSIXct format, and one column "diff" in times format (chron package). What I am trying to do is as follows: For each day

Is there any really easy way to truncate integers with several consecutive digits without rounding and without converting from numeric to character (using strsplit, etc.)?? Something along these lines: e.g. = 456 truncfun(e.g., location=1) = 4 truncfun(e.g., location=1:2) = 45 truncfun(e.g., location=2:3) = 56 truncfun(e.g., location=3) = 6 It's one thing using floor(x/100) to get 4 or

Dear R-help, First of all, thank you VERY much for any help you have time to offer. I greatly appreciate it. I would like to write a function that, given an arbitrary number of factors from a data frame, tabulates the number of occurrences of each unique combination of the factors. Cleary, this works: > table(horse,date,surface) <SNIP> , , surface = TURF

has anyone in this list ever tried to make a javascript color picker something like http://www.daantje.nl/blog/index.php?buttonID=37 or http://typetester.maratz.com/ i just thought i''d ask before i force myself to doing this. thanks mark renn _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org

Hello, I have a couple questions regarding generalized linear mixed models specifically around fitting the random effects terms correctly to account for any pseudo-replication. I am reading through and trying to follow examples from Zuur et al. Mixed Effects Models and Extensions in Ecology with R, but am still at bit unsure if I am specifying the models correctly. Background information: Our

After trying to find if there was a color picker in the FAQs and the help, I thought I would send a post here. I was overwhelmed with all the wonderful color choices R has predefined (discovered after typing in colors()) but can't figure out what they all (by name) look like. Is there a color picker or some other method to display all those colors next to the name? I think I can put together

Finally found a nice date chooser script (http://projects.exactlyoneturtle.com/date_picker), but am a little confused how to implement it. So I put this where I need the date picker: <a id="_name_link" href="#" onclick="DatePicker.toggleDatePicker(''name'')" class="demo_link">[ choose date ]</a> <div

I was surprised just now to find out that `topenv(emptyenv())` equals ? `.GlobalEnv`, not `emptyenv()`. From my understanding of the description of `topenv`, it should walk up the chain of enclosing environments (as if by calling `e = parent.env(e)` repeatedly; in fact, that is almost exactly its implementation in envir.c) until it hits a top level. However, `emptyenv()` has no enclosing

Hello, Is there a color picker somewhere that is integrated with rails? Specifically a I''m hoping for a full 24-bit picker with sliders, etc, that can interact with rails objects, such as updating a form that rails has setup, or just injecting it''s chosen value into an input value that rails has set up to put back into an object after submission. Thanks, Avram

I?ve got the following scenario: I need to store information about an R function, and retrieve it at a later point. In other programming languages I?d implement this using a dictionary with the functions as keys. In R, I?d usually use `attr(f, 'some-name')`. However, for my purposes I do not want to use `attr` because the information that I want to store is an implementation detail that

Howdy folks, As I was putting together a rough form for a rails app, I got to thinking how much smoother (in my siytuation) a little calendar widget would be than the default date picker selects. Does anyone know if such a thing exists ? I suspect it would have to be somewhat designed with rails in mind to populate the right kind of post params for convenient use at the controller end.

does anyone else have major probs with Firefox as installed on CentOS5? ever since the RPM for FF3 came out it has been crashing daily. Usually when I use Save As... or Browse... or anything else that brings up the Gnome file picker. After the crash I re-start then the file picker works for a while. Sometimes it just takes scrolling or click+drag an image or some other random action. BANG

Does anyone know if someone has created a popup calendar helper for selecting dates? The current way in rails with the multiple selects is cumbersome at best, and I didn''t see any calendar type helpers in there.
