Vector base Cosine Similarity for two Matrices -- R in UNIX
Dear All,
I am facing a problem and I would be Thankful if you can help
Hope this is the right place to ask this question
I have two matrices of (row=10, col=3) and I want to get the cosine similarity between two lines (vectors) of each file --> the result should be (10,1) of cosine measures
I am using cosine function from Package(lsa) from R called in unix but I am facing problems with it
if these files had only one row per file I can calculate the cosine similarity as following
but facing problems reading lines of two files into Vectors to do the same
I have tried to write a code, it does not give any error but does not create anything and I dont know what I am doing wrong --- (new to R)
can you please help me?
I have no knowledge of R, but I see you have two while loops nested.
Shouldn't it be just one while loop from file1,
and within that you read one record from file2?
Something like

Yes, forgot to rewind the tape on that inner file before reusing it if you want an n squared cartesian product, but perhaps you want more of a paste: line N of both files only.
If you read a file to EOF with the inner while, then the outer while loops, the inner file handle is still at EOF. Sequential disk files are like tape drives, and FILE* in C has a redundant command rewind(), which is an fseek to 0 absolute. Man Page for rewind (opensolaris Section 3) - The UNIX and Linux Forums Of course, R may rewind for you, but that seems a bit too magic.
I have changed few things including the inner loop ... but now I get an error
I cant personally see how is it going to read each of the second files lines...

Hi All,
we have a requirement to split a content in a text file every 5 rows and write in a new file .

Hello all,
I have square matrices that look like the following, I want to merge these matrices together, and add the file names as headers. This is a simple example with two variables, actually I have ~1500 variables and 10 files.
The order of variables in the matrices are consistent.

I really need help in this :(
I have a file and would like to calculate the cosine similarity of the values in it...
For now I do use R which has an easy function for doing so
test <- as.matrix(read.csv(file="file.csv", sep=",", header=FALSE))
result<- cosine(t(test))

in win32 platform, i can easily find some GUI based ftp application like cuteFtp, WsFtp and etc which provides GUI + resuming download.
pls recommend me some similar application which runs on Sun Solaris sparc 8.
hopefully it is free.
thank you very much. (1 Reply)
