Hello there, This question is relative to WindowsXP, using R 2.2.1: I am looking for a function that allows a user to interactively choose a directory so I can use list.files to process all the files in that directory. I've looked at getwd, but this is not interactive. The functions file.choose and choose.files are the right idea, but these only permit selection of a file within a

Hello all, I use R on both windows and a "mainframe" linux installation (RedHat enterprise 3.0, which they tell me is soon to be upgraded to 4.0). On windows I installed the package gplots without trouble, and it works fine. When I attempted to do the same on the unix computer, the following error message was forthcoming: downloaded 216Kb * Installing *source* package

Hello there, Using 1.9.0 on WinXP... I have a data frame, one column of which is named "rate". The column has text entries like "fast", "medium", "slow", "very slow", and so forth. I have not tried to make them factors, but maybe R did this automatically. Anyway, I would like to display on the console rows that meet a rate criterion. So I want

Hello all, I'll bet this is not complicated, but I really did hunt for information on it, and tried some ideas without success. Running Windows XP and R 2.3.1 I am using the Sound package to read in .wav files, and this works fine. The R object produced is of class "sample". I want to use some of the functions in the package Seewave to do further analysis, but this package

Hello there, Using R 2.4.0 on Solaris (Unix): I am trying to control the X axis range on a simple time of day plot. I made a test program (below) that gets file time stamp information from the files in the directory where R starts. The goal of the test program is to plot the time of day of file creation on an x axis that spans a user-specified range (like 12:00:00 to 15:00:00). If I allow

Hello I have data in many files in a directory, how can I loop through the files in a given dir in-order-to build a data.frame? thanks

Hi there, I have some data which are convenient to enter as lists. For example: t1<-list(fname="animal1",testname="hyla",dspkr="left",res1=39.7,res2=15.0) t2<-list(fname="animal1",testname="bufo",dspkr="left",res1=14.4,res2=56.1)

Hello all, I found a package I want to try listed at http://www.maths.lth.se/help/R/.R/doc/html/packages.html I am using R 1.9.0 on winXP. The package is called R.audio When I tried the example, it did not work and produced the error message: Error: Object "Sound" not found Normally I would assume that I have to download a package and I would go looking for it...

Hello list, I wrote a simple program to plot data on polar axes, taking advantage of the plotrix package and its function radial.plot. The basic plot works fine, but I am having difficulties with the formatting. There are three problems, but I thought I would attack them one at a time. Here is the first: If my data set contains values with all vector lengths between 0 and 100 (and various

Well I think a sinusoid shouldn't totally trash the encoder state, so I still think theres a bug lurking around in there. The denoiser just prevents it from ever making it to the encoder. Just from browsing through the speex code and from what I've learned reading through the mailing list, it looks like there are a few places where checks are in place to prevent sinusoids from

Hi, Is there a package to perform a sine function fitting to XY data? Thx, Ashz -- View this message in context: http://r.789695.n4.nabble.com/Sine-function-fitting-tp3000156p3000156.html Sent from the R help mailing list archive at Nabble.com.

Interestingly enough.. I started playing around with preprocessing options in 1.1.6 and happened upon the denoise filter (SPEEX_PREPROCESS_SET_DENOISE). When i run the test tone using that option it is completely filtered out and I just get (complete) silence. When the test tone is intermixed with regular voice I only get the voice. So while i still don't quite understand why the test tone

Hi I have attempted to install Samba on an ageing Motorola running SVR3. Unfortunately it has a limitation of 14 characters for filenames, which means that when I untar the package, many of the files are not created. Does anyone have a solution to this problem, or am I stuck? Many thanks -- Pete ---------------------------------------------------------------- morph@morhp.dircon.co.uk

Hi list, I'm looking about lda function. I'd like to know how calcolate the value of the discriminant functions for the original datas. I see that in the result object "lda" there is $scaling a matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical. I'd like to have the value of the discriminant

An update: I found that the "ADD32: output is not int:" messages are caused by the enhancer. When I turn the enhancer off, the messages vanish, but the "freak out" of the codec is still there - so the problem seems not to be related to the overflow messages. best regards, Frank ---------- Urspr?ngliche Nachricht ---------- Von: Frank Lorenz <Frank_wtal at web.de> An:

Hi Jean-Marc, dBFS means dB relative to digital full scale. In other words: a sine value of -42 dBFS will, on a 16 bit PCM signal, swing between 131 and -131 only (16384 * 10^(-42/20)) So we are far below +/-8000. At the moment, I'm out of ideas how to debug systematically. That even very small rounding errors alter pitch values fundamentally makes the situation worse for me, because it

Hi Jean-Marc, all, I didn't get any response to my issue up to now and would like to now if anyone can reproduce this behaviour and if there is some idea what happens. I am willing to fix this issue, but because I do not know the internals of speex, I need some advice on how to proceed... best regards, Frank Frank Lorenz <Frank_wtal at web.de> hat am 21.

Hi, I'm quite sure we found a bug inside the codec (1.2rc1, wideband mode). It only occurs when speex is compiled with the FIXED_POINT flag. I feed in a 2000 Hz sine wave (-15 dBFS). When I simulate a single frame loss (i.e. pass a null pointer to speex_decode_int as second parameter for just one frame), the decoder starts to freak out a second later: It produces horrible noise with 0 dBFS.
