Frontlines fuel of war - Problem
Hi,
I installed this game Frontlines fuel of war with wine 0.9.57,
it installs fine (2 DVDs german version), patching to 1.01 - no
problem. Starting from DVD does not work, so I have to use
a no-cd help.
But here is another problem :

Line Graphs
Hello,
I want to plot 6 line graphs. I have 10 points 0.1, 0.2, 0.3, 0.4, 0.5, 0.6,
0.7, 0.8, 0.9 and 1.0.
At each point say 0.1, I have 6 variables A, B, C, D, E and F. The variables
all have values between 0 and 1 (and including 0 and 1). I also want to
label the x axis from 0.1 to 1.0 and the y axis from 0.1 to 1.0.
My goal is to plot a line graph representing the mean of the variables at

Lattice / Trellis analog of axis(graphics) ?
My question is so basic that I am (almost too) embarrassed to admit that
I could not find an answer after an hour's worth of homework.
What is the Trellis / Lattice analog for the axis(graphics) function
that enables the creation of axes in locations other than the default
(i.e., bottom for X axis and right for Y axis) ?
For example when plotting mileage against weight (in American

Is it possible to highlight search keywords in results?
I''m wondering if ferret has any built-in search/replace mechanism that
I might be able to use to highlight the query data in each search
result. The reason I think this would be a good idea is that I could
end up having to practically duplicate the ferret query parser just to
interpret the query so that I can figure out how to highlight the
keywords in the search results. Just in case

Need help to locate my mistake
Dear readers
I would like to make General Linear Model (GLM) for the following data set

xOnes<- matrix(1,nrow=n,ncol=1)
x<-cbind(xOnes,fuelData[,3])
y<-fuelData[,4]
theta<-((t(x)%*%x)^(-1))%*%t(x)%*%y

Dos To Unix?
If we drag a file from a Windows directory - say autoexec.bat and drop it
onto a samba mapped Unix drive, when we then go to the Unix box and vi the
file all the lines end in the DOS EOL character (^M) is there any
option/configuration in samba to make it convert DOS text files to UNIX
format?

Ruby/Odeum vs. Lucene Performance
