vec_out = TRUE TRUE TRUE TRUE
or posictions values = TRUE: vec_out = 1,2,3,4

avoid NA in list
Hi!
I have list, for example:
...
[[22]]
[1] 27 51 69 107 119
[[23]]
[1] NA
[[24]]
[1] 54 57 62
And I would like to avoid NA value. Similar way like I may do it in vector
using na.value() function.
Do you have any idea?

about isoMDS method
Hi,
For example:
I built a half matrix "w" using a daisy(x, metric = c("euclidean"))
http://www.nabble.com/file/p25211016/1.jpg
And next I transformed this matrix "w" using isoMDS function, for example
isoMDS(w, k=2) and as result I got:
http://www.nabble.com/file/p25211016/2.jpg
And now I have two questions:
1. If number in matrix w[2, 1] (= 0.41538462) match

Quad monitor graphics card.
Hi there,
I have 4 identical monitors. So I decided to buy (not to expensive,
around 100USD) quad head graphics card. I do not need anything

monitors. I found following cards:
Nvidia Quadro NVS440
Nvidia Quadro NVS420
Both are actually dual GPU. Could you
