similar to: Aggregate certain rows in a matrix

I have a directed graph which is represented as a matrix on the form 0 4 0 1 6 0 0 0 0 1 0 5 0 0 4 0 Each row correspond to an author (A, B, C, D) and the values says how many times this author have cited the other authors. Hence the first row says that author A have cited author B four times and author D one time. Thus the matrix represents two groups of authors: (A,B) and (C,D) who cites

Hello I hope this question is okay: I have set up a radio with icecast2 and ices2. Everything works. I can access it from http://radio.protestbandet.dk:8000/stream? and? http://radio.protestbandet.dk:8000 I can listen to my radio in RadioDroid on my android phone, and I can listen via https://liveonlineradio.net/horsens-garage-radio in Firefox on my computer with Ubuntu.

Hello, I had an Inbox with 975,604 emails on ext3 filesystem. I keept getting dropped on the comand "copy 1:2000 inbox2", the syslog gave me an error message indicating "out of memory" problems. This despite the fact that the server has 800MB of ram free. Anyways, I asked if I could manuanlly move the files at the filesystem level or if that would mess up dovecot (break the

Hi ! I use Samba with OpenLDAP. The Samba users information are keept in LDAP. I'd like to keep the login scripts in LDAP. Something knows how can I do this ? And how Samba would read the login scripts in LDAP and not in netlogon directory ? Thanks, Bruno Stella PS: Sorry by my English :-)

Hola Juan. ¿Si yo en vez de querer obtener la media quiero sacar el porcentaje de casos que son menores que la media como lo haría? Saludos, Sebastián.

Dear list, I want the 1st, 2nd, 5th, and 6th columns of mtcars. After copying them, the columns become numeric class rather than data frame. But, when I copy rows, they data frame retains its class. Why is this? I don't see why copying rows vs columns is so different. > class(mtcars) [1] "data.frame" > head(mtcars) mpg cyl disp hp drat wt qsec vs

Estimados: Dentro del aggregate utilice un table, son cuatro los valores que puede tomar la variable, ¿como puedo desarmar la lista y crear cuatro variables nuevas donde le asigne 0 si no se da ese valor?

Estimados usuarios de R: Estoy aprendiendo a usar el comando aggregate. Por ejemplo tengo la siguiente tabla: A B C X1 X2 X3 X4 1 1 1 10 0,333333333 25 1 2 1 1 20 1,818181818 36 1 3 2 1 30 1,428571429 46 1 4 2 1 11 0,35483871 26 2 5 3 2 21 1,75 37 2 6 3 2 31 1,409090909 47 2 7 4 2 12 0,375 27 3 8 4 2 22 1,692307692 38 3 9 5 3 32 3,2 50 3 10 5 3 13 0,65 28 3 Yo quiero agrupar usando como

Daniel, en vez de mean utilicé table. Entonces me genera una lista y quiero que quede una matriz. Unlist no me sirve porque me pasa todos los valores a un vector y me pierdo de saber a que caso corresponde. Saludos, Sebastián.

Hello, I am stuck with selecting the right rows from a data frame. I think the problem is rather how to select them then how to implement the R code. Consider the following data frame: df <- data.frame(ID = c(1,2,3,4,5,6,7,8,9,10), value = c(34,12,23,25,34,42,48,29,30,27)) What I want to achieve is to select 7 rows (values) so that the mean value of those rows are closest to the value of 35

Dear all, I have a simple question which I unfortunately do not seem to be able to solve myself. I have a (NxK) matrix and want to generate a new matrix by multiplying each row with itself such that the new matrix has dimension ((N*K)xK) (or better, generate an array with dimension (K,K,N)). I tried apply, but that did not work. Any suggestions? Thanks! Stephan ## Here is a simple

The documentation for `aggregate` makes it sound like aggregate.formula should behave identically to aggregate.data.frame (apart from the way the parameters are passed). But it looks like aggregate.formula is quietly removing rows where any of the "output" variables (those on the LHS of the formula) are NA. This differs from how aggregate.data.frame works. Is this expected behavior?

Hi, I use the code below to aggregate / cnt my test data. It works fine, but the problem is with my real data (33'000 rows) where the function is really slow (nothing happened in half an hour). Does anybody know of other functions that I could use? Thanks, Hans-Peter -------------- dat <- data.frame( Datum = c( 32586, 32587, 32587, 32625, 32656, 32656, 32656, 32672, 32672, 32699 ),
