...ne backends. If you don't provide an implementation of wdf_upper_bound(), the default is to use the collection frequency of the term, so provided that information is available in the lucene files, the lack of wdf_upper_bound information isn't a show stopper. > I think this data will be caculated when doing copydatabase, I will update > the code later That's probably a good plan though.

Hi,All I use HTB to control traffic.Here is my script: /usr/sbin/tc qdisc del dev nas0 root /usr/sbin/tc qdisc add dev nas0 root handle 1:0 htb default 60 /usr/sbin/tc class add dev nas0 parent 1:0 classid 1:1 htb ceil 896kbit rate 896kbit prio 0 burst 60k /usr/sbin/tc class add dev nas0 parent 1:1 classid 1:10 htb ceil 896kbit rate 537kbit prio 1 burst 60k /usr/sbin/tc class add dev

may some one please help me to sort this out, i am trying to writ a R code for calculating the frequencies of the amino acids in 9 different sequences, i want the code to read the sequence from external text file, i used the following code to do so: x<-read.table("sequence.txt",header=FALSE) then i defined an array for 20 amino acids as following:

before I accuse somebody to "overbill" I would like you to calculate with me: Rate: 0.0189 for calling Taiwan via NuFone Duration: 930 seconds Lets vote for the answers: 0.7269 or 0.2929 ??? bye Ronald Wiplinger

Dear R Users I'm writing my first simulation in R. I've put across my problems with a smaller example in the attachment along with the questions. Please help.

This is a eaeir way to ask my prior question: I want to caculate how many an exact day of the month there is between two dates. For example; How many 7th of the month is there between "1998/12/17" and "2000/1/7". To make the problem simple, the day of the month (7) is the day in the 2nd date.

Hello£¬experts I am working on a simulation of effect of artificial selection on certain population in Animal Breeding.I am new beginner in coding. I have already build a matrix A(500*500) based on this code A<-matrix(,500,500) for(i in 1:500){ for(j in 1:500){ ifelse(i==j,A[i,j]<-1,A[i,j]<-0) } } and I need to caculate A2 base on A and X1(4500*4500).Here are the codes

...d_name:term, or file_name:term1 AND field_name:term2 Until now, I found some data needed for BM25 in Xapian are not existed in Lucene: 1. doclength_lower_bound?doclength_upper_bound 2. wdf_lower_bound?wdf_uppper_bound 3. total_length 4. doclength(for each document) 1-3 are statistics data, can be caculated when doing copydatabase, and store them in somewhere. But doclengh is hard to do this way. 1. some other data instead of doclength? 2. Xapian support other rank algorithm which does not need doclength? Is there some suggestions to solve this problem? And the demo patch is here: https://github.com...

I did not simulate my data with mean. besides I caculated R2 by myself but it cannot match the R2here I think R2=1-sum((y-x%*%lobj$beta)^2)/var(y)*19 #I have 20 observations...my R2 is lower than the one here Thanks a lot -- View this message in context: http://r.789695.n4.nabble.com/the-output-of-function-lars-tp3078460p3078460.html Sent from the R...

Hello list, I've got a question from reading Using Samba 3rd, where it puts: ... the final permission is caculated by below filters in the order used by Samba: 1. Apply any DOS attribute mapping options << I take this as either map DOS attributes to execute bits, or store DOS attributes in extended attributes. Correct? 2. Apply the create mask settings 3. Apply the force create mode settings....

Dear all I'm trying to caculate the MLEs for parameters of Inverse Gaussian distribution (in a k-sample problem with common mean) by using EM-Algorithm. I found some package for EM-Algorithm that are useful for missing or incomplete data and are not helpful for solving my problem. (Exactly, the problem is: Let Xij, i=1,..,k , j=1,...,ni, be a random sample from IG(?,?i). So the

hi: I want to know the math behind the "tm" package findAssocs(). I have found that someone had asked the question before, and have a good explanation by Rick. ?]http://r.789695.n4.nabble.com/findAssocs-td3845751.html?^ But I still don't understand how to calculate the correlation value between the two vectors. For example: # Correlation word2 with word3

Yes - TfIdfWeight doesn't ever use the document length (at least with the normalisations currently

hi,r project I am a new user who has some questions about r tool,I have some original data file in netcdf format which is a famous geometry data file format, The file contains very large weather information from every zone of the world,I want to extract only a part of them to calcuate, like the information in a city or the information between exact latitute range and longtitude range, can r tool

General goal: Write R code to find the inverse matrix of an nxn positive definite symmetric matrix. Use solve() to verify your code works. Started with a 3x3 matrix example to build the code, but something dosen't seem to be working. I just don't know where I am going wrong. ##Example matrix I found online A<-c(4,1,-1,1,2,1,-1,1,2) m<-matrix(A,nrow=3,ncol=3) ##Caculate the eigen

Apologies for what might seem like an simple question. I have written a model which gives me a frequency distribution for a particular score within a set. What I now want to do is loop this so that I get many different frequency distributions and append them to a table with a collum which specifies which loop the frequency distribution is from. What I wantto end up with would look something like

...lify H: sd = sqrt [ ( Si (Xi - mean(X) )?? ) /n ] -> simplified computation -> sqrt [ (n * Si( X?? ) - ( Si( X ) )?? )/ n?? ] This simplied formula is much easier in iterative programming, since I don't have to keep every element of X. E.g.: I have a vector X[1:10] and I already have caculated Si( X[1:10]?? ) (I will call this A) and Si( X ) (I will call this B). When X gets extendend by 1 element (eg. X[11]) it easy fairly simple to calculate sd(X[1:11]) without having to reuse the elements of X[1:10]. I just have to calculate: sd = sqrt [ (n * (A + X[11]??) - (A + X[11]??)?? ) / n?? ]...

Hello, My name is Maria, MBA student in Sanfransisco, USA. In my credit scoring class, I have hard time making "transition matrix", which explains probability especially in relation to "Markov chain model". It is regarding people's monthly credit payment behavior. Does R have function to caculate it? I am actually a novice in using 'R'. Please help me!!! Maria
