Hello. There are so many sound files in /var/lib/asterisk/en. Is there an easy way to let me play back all of them one by one while I am watching CLI to see the current file name?

Hi All, I have a vector of data on which I am operating. The equation with which I want to operate on the vector has a value k. I want to run the equation and output a new vector, each time replacing k with each value from the sequence I defined. I have thought about using for loops and such, but this seems like overkill. I am wondering if there is a simple solution that would allow me to

Hello, all, I have a Linksys 3102 from a VoIP provider. It use SRV record to register to the provider's SIP server. When I configure this line into my Asterisk, the register doesn't work if I use their domain name. So it like this: If I use register => user:pwd at proxy.provider.com then I got: [2010-05-17 11:47:19] WARNING[2366] chan_sip.c: No such host: proxy.provider.com

Dear R colleagues, I am trying to plot some geophysical data as a filled contour on a continent map and so far the guidance from the R-help archives has been invaluable. The only bit that still eludes me is the colour key (legend) coming with filled.contour: I prefer to generate my own colour palette, mainly based on the quantiles of tenths of the data...

I am using the PAM algorithm in the CLUSTER library. When I allow PAM to seed the medoids using the default __build__ algorithm things work well: > pam(stats.table, metric="euclidean", stand=TRUE, k=5) But I have some clusters from a Hierarchical analysis that I would like to use as seeds for the PAM algorithm. I can't figure what the mediod argument wants. When I put in the

Dear R-helpers, I'm plotting geophysical data in the form of contours using "filled.contour". The display would be much more effective if the areas with negative values could be color coded by -- say -- "cold colors" in the range of blue to green, and conversely the areas with positive values got plotted with "war...

Hi I am using rsync for backup on the disks of a Linux backup server. Obviously the server could store more data it the data were compressed. I read the "rsync -> tar" thread. Unfortunately, a compressed file system for Linuthere does not seem to exist yet. However, rsync can use compression for file transfer. Would it be possible to implement an option to store the data on the

Hi everyone, I have written a class with methods that extend generic functions such as as.data.frame or show. When I load this package, I want to ensure that these methods - along with the other functions in the file - are added to R's search path or updated, if necessary. I have made a package using check/build/INSTALL. Will a simple library() call on the package accomplish this? I

I have been coding a C-program which will read data from the netCDF format (a commonly used file format in the geophysical research community: see Unidata's URL for explanation: http://www.unidata.ucar.edu/packages/netcdf/), and have got to the point where I don't know what the error message mean.
