...R, could you explain to me how to resolve this question: If this is a matrix: Element S1 S2 S3 S4 0 0 1 0 1 1 0 1 0 0 2 1 0 0 1 3 0 0 1 0 4 0 0 1 1 5 1 0 0 0 1. How is possible to ompute the minhash signature for each column if we use the following three hash functions: h1(x) = 2x + 1 mod 6; h2(x) = 3x + 2 mod 6; h3(x) = 5x + 2 mod 6. 2. Which of these hash functions are true permutations? 3.How close are the estimated Jaccard similarities for the six pairs of columns to the tru...

It looks like a homework assignment. It also looks like you didn't read the documentation carefully enough. The 'len.out' argument in seq is solely for specifying the length of a sequence. The 'quantile' function omputes the empirical quantile of raw data in the vector 'x' at cumulative probabilit(y)(ies) given in the weights' argument, with interpolation I'm between. For example quantile(x=c(2.3, 1, 7, -4, 1), weights=c(0.60,0.45)) 60% 45% 1.52 1.00 So to do what you want, there may be a cann...

Hello everyone. My name is Jo?o Paulo I am a master's student in the course of omputer science. I intend to create a package for the R that makes the SQL language commands available for use. I know that there are already some packages that execute SQL commands within R. However, most of these commands require querys to be passed as a string. I wish SQL commands could be used more...

Dear list users, I need to learn about MCMC methods, and since there are several packages in R that deal with this subject, I want to use them. I want to buy a book (or more than one, if necessary) that satisfies the following requirements: - it teaches well MCMC methods; - it is easy to implement numerically the ideas of the book, and notation and concepts are similar to the corresponding R
