strange loss of accuracies under Win NT
Dear All,
It's been several times I observed a very strange behaviour with R 1.2.0
under Windows NT 4.0 (with sp5): accuracies are lost in many cases. Things
are back to normal when I exit R and restart it. Here is an example of my
last encounter with this:
> bt1 <- c(7.3, 8.1, 8.4, 7, 6, 7.2, 6.7, 8.3, 9, 7.4, 8.6, 6.2, 6.9, 7.6,
5.3, 5.6)
> bt1
[1] 7 8 8 7 6 7 6 8 9 7 8 6 6 7 5 5
> 1000*0.1
[1] 0
> log(0.9999)
[1] -Inf
> log(1.9999)
[1] 0
> log(2)
[1] 0,6931472
I used R 1.1.1 on the same computer quite a lot, and never saw this. Has

Call signalling on BT FeatureLine Compact (Sangoma A200)
Hi,
I have a TrixBox install with a Sangoma A200 and 4 FXO ports, there
are 3 BT lines connected directly to these ports.
One of the lines has BT FeatureLine Compact and this is the line I am
having problems with, the other 2 lines are working perfectly,
detecting CID, answering incoming calls and placing external calls via
SIP devices.
I am receiving a error log entry:

Kolmogorow-Smirnow-Test to check if Data comes from Subbotin distribution
Hi,
I have a Data Set x and I want to check with a Kolmogorow-Smirnow-Test, if x comes from a Subbotin Distribution, whose density function is:
function(x,location,scale,tail) # Exponential power (=Subbotin)
{
const<- 2*scale*tail^(1/tail) *gamma(1+1/tail)
z<- (x-location)/scale
exp(-1/tail*abs(z)^tail)/const
}
How can i do this? Thank you

[PATCH 0/9] tools: remove or disable old/useless/unused/unmainted stuff
depends on "autoconf: regenerate configure scripts with 4.4 version"
This series removes some of the really old deadwood from the tools build
and makes some other things which are on their way out configurable at
build time with a default depending on how far down the slope I judge
them to be.
