Hi, I'm trying to use a similarity matrix (triangular) as input for pam() or fanny() clustering algorithms. The problem is that this algorithms can only accept a dissimilarity matrix, normally generated by daisy(). However, daisy only accept 'data matrix or dataframe. Dissimilarities will be computed between the rows of x'. Is there any way to say to that your data are already a

Hi, I want to change my running software raid1 from ext2 to ext3. I'am currently running RH 7.1 with 2.4.18. The raid constist of two 40GB disks on a seperate UDMA Controller (HPT370). The system is installed on another disk. Can I just use tune2fs -j /dev/md0, or do need to rebuild the raid from scratch with ext3? Many thanks for your help! Regards, Ingo

Dear R users, I want to do a fitted.contour plot of selected columns of a dataframe M with M$AM and M$Irradiance as x and y axes respectively. The level of the contour shall be determined by M$PR. Some words on my data first. Dataframe M looks like: head(M$Irradiance) [1] 293 350 412 419 477 509 head(M$AM) [1] 2.407 2.161 1.964 1.805 1.673 1.563 head(M$PR) [1] 70.102 72.600 75.097 80.167

Hello, I would like to use my own dissimilarity matrix in a PAM clustering with method "pam" (cluster package) instead of a dissimilarity matrix created by daisy. I read data from a file containing the dissimilarity values using "read.csv". This creates a matrix (alternatively: an array or vector) which is not accepted by "pam": A call

A large test I ran on flac 1.0 recently finished so I thought I'd post the results. I took about 60 CDs, totalling around 30 gigs uncompressed, and compressed them all using all 10 of flac's default compression modes (-0 through -9). The CDs are of a wide variety of music; I think the only major genres not represented are country and rap (freudian slip). Anyway, the raw numbers: Opt

Hi, I'm planning on a new mail infrastructure which constists of multiple 'frontends' running webmail & public access pop/imap, which would communicate over imap/pop to 'backend mail stores'. My original idea was to run dovecot on the backends, use a predition on the frontends to proxy imap/pop and also run imapproxy in front of webmail [squirrelmail]. I've since

Hi all, Two days ago MachineBasicBlock got ilistified. What does this mean and how does it affect you? Read on. MachineBasicBlock used to have a std::vector<MachineInstr*> to represent the instructions it constisted of. This representation has the following problems: 1) O(n) insertions/removals to/from anywhere but the end of a basic block (removals are very comomn in peephole optimizers and insertions in register allocators) 2) After an insertion all std::vector<MachineInstr*>::iterators ar...

Interesting figures. Some corresponding figures for flac 1.0 for a set of 404 CDs, with a total of 4357 tracks are: Opt Uncompressed Compressed Ratio Encode Time --- ------------ ----------- ------ ----------- -8 234507744748 127468328349 0.5436 n/a Admittedly, this set includes at least one country album, and has a fair share of jazz in it. The worst-case track in this set

Greetings, I am reasonably experienced with R but I recently tried to do some clustering using the "cluster" package, in order to see if it would help. I only tried this once with the 1.3.1 version and it worked (I don't quite remember which method I used). Now, I tried with the 1.4.0 version and no clustering function seems to work with matrices that contain NAs, even though
