Literature analysis
Dear all,
i am new in R. I am writing a review paper about batteries. However, i
am interested in analyzing all the papers by keywords, author,
references and year.
This could be done by "refviz" a software, which is only running on
windows machines and which is not free.
So my question to you is, is it somehow possible to write a script that
can do all of this work?
And if yes, with

question about centroid-linkage (cluster analysis)
...hc_c$merge
[,1] [,2]
[1,] -1 -2
[2,] -3 1
[3,] -4 2
[4,] -5 -6
[5,] 3 4
> Y.hc_c$height
[1] 2.000000 1.914214 1.517428 2.000000 9.692575
So, from this it would appear that the distance between the last two clusters is 9.692575!
How can it be?

convex hull for cluster analysis
...,] 23 94
[10,] 23 75
I was expecting hull to give me a few 2D points that would enclose the 100 random points generated,
but this doen't seem to be the case.
Probably I'm using the wrong tool here.
Any help with this would be greatly appreciated. Thank you.

The second result is the correct one. Why, then do
I get the y[701]=10.07404? This function is not supposed

Any help is greatly appreciated.

greek letters in rgl plot3d
...gt; plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5)
The expression(alpha) appears as "alpha", rather than as a greek symbol.
I suspect greek and mathematical symbols in general can be added to a plot3d
in rgl. Is that true?

rgl and lighting
...diffuses red light from the front face. I thought I could do:

but...the front side doesn't show any red-iness. Same goes for specular and ambient.
What am I doing wrong here? How should the fron side show in red colour?

sourcing a linux file with "system"
...nt variables.
I have tried:
> system("source /home/james/build//ccp4-6.1.13/include/ccp4.setup")
and got:
sh: source: not found
In fact, using Sys.which("source") I get an empty string.
How can I source that ccp4.setup file from within an R session?

summing a large, partitioned data frame
...YM and replace the sum
in a unique row in the new data frame. In other words there's first a partition and then
a sum.
I have tried with a for loop, but it really takes too long.
I was wondering whether anyone knows of a better and faster way of doing this operation.

recompile R using ActiveTcl

But...is it by any chance possible to "just" recompile the bit affected by
Tcl/Tk, like, for instance, to install tcltk with some environment variable
pointing at the right ActiveTcl library?
Many thanks for your suggestions and help.

automated image processing
Hi,
I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way.
I had a look on biops and EBImage (Bioconductor) but they are not automatic...
Did you already use/know a such package ?
Thanks,

new R package. How to hide data file
...isible to users. If I call SYMINFO as .SYMINFO, the functions needing
this bit of data do not work anymore, even if I replaced
data(SYMINFO)
with

Does anyone have ideas why this is happening? Would you handle the whole process differently?
Kind regards,

OPUS on cortex M4
...ssy, FLAC is lossless.
Visit https://xiph.org/flac/
As Timothy said, Opus is optimized for human
ears. I haven't worked with bird calls for over
40 years, but my recollection is that birds and
humans generate sound very differently.
Birds have no vocal cords, instead using a
vibrating fleshy membrane. Also, they have
two of them which can be used independently.
I don't feel you should be using Opus (or any
lossy encoder).

Martin

wilcox.test construction in r
Hi, I am very confused with constructing the wilcox.test in R.
I have two populations 'original' and 'test'.
I want to know if the 'test' is generally 'lower' than original.
I use alpha of 0.05.
So do I write the function as wilcox.test(original, test, alternative="l")?
or wlcox.test(original, test, alternative = "g")?
or wilcox.test(test,

problems with rgl in Ubuntu 'gutsy'
...In addition to that, the image is like "frozen", it can't be either rotated or shifted at all.
In short, rgl seems not to behave according to expectations. No error messages appear at any stage.
Has anyone a clue on what's going wrong here?

Fourier Transform

I wanted to perform a fourier transform on high frequency financial data. I
have searched and have not found much on this topic for R. I was wondering
if anyone has used any libraries for it or have come across any papers I may
read.
