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: downloaded 216Kb * Installing *source* package

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. So I want

fit sine?
Hello list, I am making scatterplots of data that vary sinusoidally over 24 hours. With a bit of previous help from this list, I now can get an x-axis with time tics from 00:00 on the left edge to 12:00 in the middle and 00:00 on the right edge, i.e., just 24 hours. Now I would like to fit a sin function to the plot. I've looked all over CRAN and the web in general, but have not found a

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). If I allow

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 (and various

question about tool collisions
Recently I got introduced to two packages: {seewave} and {audio} . Turns out they both have a tool to call a system audio tool, and in both cases the name of the tool is play(). Naturally these two tools do slightly different things with different arguments. So, what should a user do, and more to the point, what should R do? If I've learned the right things about environments, I

melting columns
Hello, I'm using R to run a acoustic analysis software called Seewave. I ask the code to extract a list of variables from my recording, and the program give ONE table for each of these. The tables consist of a two column data.frame with the time in column 1 and the frequency in column 2. However, for my purpose I need only one column with the time first and the frequency second. I tried

library installation problem, invalid regular expression in help indices
Hi, I have a strange package installation problem after update to R 2.11.0 on Fedora Core 12. A colleague of mine with the very same Fedora and R versions doesn't have this problem, while logging on to his computer but installing from my settings and into my local library path also shows the problem, so it seems to be related to some of my environment settings. Installation of several

patch to enhance sound module for 96 kHz/24 bit sample sizes
Greetings Matthias, Thanks again for your sound module. I did not ever manage to find the time to play with phase equations, but I found I needed the module for a new project involving bats. I needed to do some work @ 96 kHz/24 bit sample size, and found the limitations of the sound package stop at 48 kHz and 16 bit samples. Here's a patch to bring things up to 96/24. Sorry I cannot

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 -- Pete ---------------------------------------------------------------- morph@morhp.dircon.co.uk
