lowess + turnpoints = doubling integers?
Happy New Year, r-helpers! I am using lowess to smooth a scatter plot, xx<-lowess(xinput,f=.04) #defaults for other args followed by turnpoints(xx$y) #defaults for other args I plot the smoothed result as well as turnpoints (using yy$tppos) on top of raw data plot. Result is exactly as expected, graphically. For another purpose, I calcuate the difference between turnpoints (representing

Use voice onset timing to identify voiceless
In increasing the computation time and bit rate with VBR: Has anyone considered implementing the standard audiological recognition technique of using the duration of zero energy (voice onset timing) to identify the presence of voiceless sounds? I would like a means of determining whether or not a given window will be full of voiced speech or not.

three related time series with different resolutions
I have three time series, x, y, and z, and I want to analyse the relations between them. However, they have vastly different resolutions. I am writing to ask for advice on how to handle this situation in R. x is a stimulus, and y and z are responses. x is a rectangular pulse 4 sec long. Its onset and offset are known with sub-millisecond precision. The onset varies irregularly -- it doesn't fall on neat 1/2 sec or sec boundaries for example. y is a sampled continuous waveform. It is highly noisy, and it is actually well represented by samples 1/2 sec apart or so. z is a very short pul...

A model for disease progression
...indicates the progression of a certain age-related disease. At a certain point in time, a population was sampled; and I have measurements for the age of each individual, and their disease stage. (Disease stage is an ordered factor, none<A<B<C<D.) I hypothesize that the rate of disease-onset depends on age, but that (once the disease has started) its rate of progression depends on the current disease stage and not on age. I would like to plot the data in a sensible way, to let me see if this hypothesis is reasonable, and to let me explore possible functional forms for the two rates....

Reducing the size of a large script top speed onset of execution
Colleagues, (R 2.10 on all platforms) I have a lengthy script (18000 lines) that runs within a graphical interface. The script consists of 100's of function followed by a single command that calls these functions (execution depends on a number of environment variables passed to the script). As a result, nothing is executed until the final line of code is read. It takes 15-20

RODBC and NULL values

I have all my data in Filemaker 8.5, but it is automatically exported into PostgreSQL for analysis as Filemaker's ODBC and JDBC access is awful, slow and has a tendency to crash. I have disability data where for each patient there is a survival time in years from disease onset to a particular disease stage, namely unilateral support, bilateral support, wheelchair use, and death. Valid values may include NULL (patient hasn't reached that stage), 0 (for example, patient needed support immediately at disease onset), and any positive integer. When I query the database m...

strucchange-esque inference for glms ?

combining same-day lab measurements with 'apply'
...me that I could use strsplit as well..). It may be irrelevant, but the 'date' variable is a Date class object. I've tried first converting this to a character object but didn't get anywhere. Further, I'll use the dates later with difftime to figure the subjects' age at the onset of their condition, so I'd like to avoid converting between classes too much. Any advice would be greatly appreciated. Here is the code to build the sample data and the working for loop as well: > dum <- data.frame( + id = c(2,2,2,3,4,4,4,4,5,5), + x = sample(15:30,length(id)),...
