RE: [R] hdf library for windows

2003-11-30 Thread Mulholland, Tom
The question puzzled me at first, because of your use of "library". It looks as if the hdf5 r "package" utilises the "windows hdf5 library" binary. My reading is that you will have to compile the package yourself after you have downloaded the hdf windows dll from hdf.ncsa.uiuc.edu The instruction

Thanks. I guess we have to be content to approximate this via: apropos("POSIXt$|POSIXct$") although this supposes we know that POSIXct inherits from POSIXt and its not clear that there is a reliable way to discover that for S3 classes. --- Date: Sun, 30 Nov 2003 13:10:52 -0800 (PST) From

Re: [R] fitting a theoretical distribution with truncated tails

2003-11-30 Thread Spencer Graves
Have you considered "fitdistr"? The documentation says that the second argument is "Either a character string or a function returning a density evaluated at its first argument." It should be easy enough to write something like the following: dweibull.trunc <- function(x, shape, scale=1,

Hi, I have recently started working with R and am not really fluent in it. I am plotting a few graphs using the qqplot function. Is there a method for fitting a theoretical distribution (e.g Weibull) with truncated tails in R? Thanks for any help! Piyush

No, the status of the optimization is only in C code until the finish. Whyever would a partially run optimization be useful? You can arrange for your optimizand to record the latest set of parameters if you wish, and then just interrupt R in the usual way. Or you can set a limit on the number
