plot circular histogram
In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I

help with simple function
I have a matrix of frequency counts from 0-160. x<-as.matrix(c(0,1,0,0,1,0,0,0,1,0,0,0,0,1)) I would like to apply a function creating a new column (x[,2])containing values equal to: a) log(x[m,1]) if x[m,1] > 0; and b) for all x[m,1]= 0, log(next x[m,1] > 0 / count of preceding zero values +1) for example, x[1,2] should equal log(x[2,1]/2) = log(1/2) = -0.6931472 whereas x[3,2] should

"reverse truncate" to extract only decimal values
hello there, Is there a way of truncating in the opposite direction so as to retain only the values to the right of the decimal?? i.e. rather than: > trunc(39.5) [1] 39 i would get something like: > revtrunc(39.5) [1] 0.5 I've been searching to no avail but I imagine there is a very simple solution!

NOT-SO-SIMPLE function!
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

Export kde object as shapefile
I am trying to estimate home range size using the plug-in method with kernel density estimation in the kernel smoothing (ks) package. Unless there is another way I am not familiar with, in order to calculate spatial area under the space I need to convert my kde () object into a spatial object somehow in order to calculate its spatial area. Could someone demonstrate how this might be done? --

Help pasting string as object name
I have a data frame containing monthly observations of the 'density' of each US state, recorded in variables named "density.AL", "density.AK", "density.AZ", and so on for all 50 states. The data frame (called d) also contains a variable called "Date" which is encoded as a string in the format "Jan-09", "Feb-09", etc. I also have

Recursive function calls
My apologies, I know that this is not a new problem, but I'm not sure how to find the answer I want to recursively loop over an object and trim trailing white space. When I use this function on a list of data.frame I get output like this: [1] "c(\" many spaces \", \" many spaces \")" "c(\" many spaces \", \" many spaces

Graphics window BUG
I thought this problem would be resolved when I switched to R version 2.7.0 (for Windows), but no - anytime I plot something that produces more than one page of graphics, the graphics window starts by showing the first page, until such time as I hit enter to show me the next page, at which time it speeds through every consecutive page and freezes on the last one. At this point the last page is

[LLVMdev] [PATCH][RFC]: Add fmin/fmax intrinsics

I could even be convinced if we wanted to add a pair of NaN-propagating intrinsics as well, for targets and languages that want those semantics, even if I disagree with them. I do think that, if we are using the minnum/maxnum names, we should explicitly note that they are

Using the output of strsplit
I successfully combined my data frames, and am now on my next hurdle. I had combined the data and quarter, and used tapply to count the entries for each unique date/quarter pair. ar= tapply(ewrgnd$gw, list(ewrgnd$dq), sum) #for each date/quarter combination sums the gw (which are all 1) dq=row.names(ar) spl=strsplit(dq) But I need to split them back into the separate date and quarter.

plot rownames
In the following example: x <- rnorm(1:100) y <- seq(from=-2.5, to=3.5, by=0.5) z <- as.matrix(table(cut(x,c(-Inf, y, +Inf)))) ## I wish to transform the values in z j <- log(z) ## Yet retain the row names row.names(j)<-row.names(z) Now, how can I go about creating a scatterplot with row.names(j) on the x-axis and j(m:nrow(j)) on the y-axis?

analyze subsample of dataframe
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
