there a contact for security issues?
* Has a vulnerability disclosure program?
* Is there a bug bounty program?
* Does R require third party authorization/connections?
Thank you

,
rownames(distF) <- paste("A",dim(distF)[1])
it gives the following error;
Error in dimnames(x) <- dn :
length of 'dimnames' [1] not equal to array extent
What am I doing wrong? Any help is most appreciated

"cuz i dont know
how looking at the original data set would help becuase the matrix under
consdieration right now is the distance matrix and how it can be altered. I
have tried as.dist, doesnt work because my matrix as i mentioned eralier is
not a square matrix.

Any help would be highly appreciated.

I checked for k in 1:100 and it runs fine; its a huge matrix and takes
atleast an hour to run before I get the results so I dont wanna run the
whole thing again and get the same error. Please help!

My question is :
In the function "plot", can one decrease the leaf label size to make them
readable and clear? I am including over 380 proteins in my dendrogram
and each leaf has a label which are currently overlapping and not
decipherable?
Thanks

oki :D
and do you know if there is an inbuilt R pacakage that calculate moving
averages over time?
i found this ,
"Calculate various moving averages (MA) of a series."
Usage
SMA(x, n=10)
EMA(x, n=10, wilder=FALSE)
but when i tried SMA , R wouldnt recognize it! and there isnt such a packa
I have tried blockrand but it works in a way that it keeps altering the block
size.. like it alternates between 8,6,12. I want a constant block size of 8
:(

finds what it is looking for in the left hand column, it will
simply replace it with what is in the right hand column (the protein
name/label) under the attribute ("label")...
Please help!
Thanks!
