file.choose but for folder/directory?
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

linux gplots install unhappy
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:

extract a row
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.

samples to dataframes
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

a little help needed plotting chron object
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).

swapping with data.frame
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)

standard library?
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...

trouble with plotrix package
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

Installation of Samba on SVR3 unix
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

Problem encoding sine wave in 1.1.6 and somewhat in 1.0.4
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

lda discriminant functions
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

Coercing character to factor
I just downloaded version 1.0.0 and several binary libraries (VR, rpart,
norm, stataread) - WinNT version. I then converted a file from Stata 6.0
to R format by using the stataread library. The file converts perfectly
and I was able to use the VR function lda on the dataframe without
difficulty. I then tried to use the same dataframe with RPART. The model

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)

get the voice. So while i still don't quite understand why the test

rpart puzzle
I've been using the package rpart with R 1.3.0 for Windows to produce
simple classification trees for some measurement data from paleontological
specimens. Both the rpart documentation and the output confirm that the
program produces splits on continuous data that leave "holes" in the
data. It is probably of little practical importance, but is there a reason

CentOS 7 and 4K display
I installed C7 along with MATE desktop...
My monitor is a 4K unit but when I goto the
System -> preferences -> hardware -> Displays
there is selection for the 4K display. It stops at 1920x1080.
The var log x file shows the 4K resolutions in the file so that is good.
How do I get the selections for 4K to show up?
Thanks,
