R devel - May 2009 - remez (signal) causes unhandled exception (PR#13713)

Full_Name: Attila Kocsis
Version: 2.9.0
OS: windows
Submission from: (NULL) (91.120.153.114)


I have installed R 2.9.0 on Windows.
Then installed signal package.
Then I issue the following commands in RGUI or rterm:

require("signal")
f1 = remez(17,c(0,0.00001,0.0625,1),c(1,1,0.001,0.001))

and the R clashes.

The possible cause of the problem is that no solution with given parameters is
possible. Maybe it runs into infinite loop.

With the command

f1 = remez(17,c(0,0.00001,0.2,1),c(1,1,0.001,0.001))

it is OK.

Well, this happens in the remez() function that calls an entry point in 
compiled code of the package signal. Please report bugs of contributed 
packages to the package maintainer rather than to R-bugs.
