similar to: for loops

First I wanted to thank both Marc Schwartz Greg Snow and for their reply. Then I needed to add a level of complexity to the problem. I would be able to create the biggest possible matrix. In other way does it exist a method to ask smthing like the following : max number of rows for a matrix if column=x?

Hi, I've noticed that if I disconnect or reconnect a phone from the net, Asterisk take long time to realize that (even more then 10 minutes). Is there a way to reduce this time, working on the configuration files? Thank you. silvia ------------------------------------------------------ Passa a Infostrada.

Hello, Given a vector I would like to rapidly identify duplicated non contiguous elements. Given for example c(1, 1, 2, 3, 2, 4, 5, 6, 4) I would like to get: FALSE FALSE TRUE FALSE TRUE TRUE FALSE FALSE TRUE In fact I need to check this on the columns of a matrix! I can do that of couse with loops but is there any function already available? Thanks

I have functions using get.hist.quote() from library tseries. It seems that something changed (yahoo) and function get broken. try with a simple get.hist.quote('IBM') and let me kow if for someone it is still working. I get this error: Error in if (!quiet && dat[n] != start) cat(format(dat[n], "time series starts %Y-%m-%d\n")) : missing value where

Yes you are right ... an example is mandatory. So ... I have a matrix of 0 with just a single 1 per row and per column I need to extract all maximal 'diagonal' submatrices Let's say I have the following matrix A B C D E a 0 1 0 0 0 b 1 0 0 0 0 c 0 0 1 0 0 d 0 0 0 1 0 e 0 0 0 0 1 well I would like to get, for this example, the two following submatrices A B C D E

Hello, I have a question about the lars package. I am using this package to get the coefficients at a specific LASSO parameter s. data(diabetes) attach(diabetes) object <- lars(x,y,type="lasso") cvres<-cv.lars(x,y,K=10,fraction = seq(from = 0, to = 1, length = 100)) fits <- predict.lars(object, type="coefficients", s=0.1, mode="fraction") Can I assign

Hi I am trying to use RODBC in R installed on Windows to access MySQL database (on a linux box). I set up a DSN and specified this DSN in R as follows library(RODBC); channel <- odbcConnect("mysqldsn"); RODB Connection 5 Details: case=nochange PORT=3306 ........ Although this seems to connect properly, running any command yields NO results. i.e. sqlQuery(channel, "show

Does anyone have a simple explanation and example on how to add histograms or barcharts to an other graph like in the example at the R-graph gallery: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109 looking at the code I'not undertand very well how to add graphs in arbitrary/clever position with an adequate scale. If somebody have a simplier example with explanations it

I have to perform ANOVA's on many different data organized in a dataframe. I can run an ANOVA for each sample, but I've got hundreds of data and I would like to avoid manually carrying out each test. in addition, I would like to have the results organized in a simple way, for example in a table, wich could be easy to export. thank you for assistance simone

thank you to both Adaikalavan and Patrick. on the basis of Adaikalavan example this is an example that point out my problems. >log_raise=function(num, exp, base){return(log(num^exp,base))} I would like to have optional fields, so some settings to be default parameters; if I declare the function as above the operator must of course input all the variables. Finally I could fix as follow.

Dear Partecipants to the list, I am searching a R function, which can calculate the inverse of one real value function. Does it exists a R code in order to make it?

I tried to use gpuCor function in the gputools package of R to calcuate the pairwise correlations of a matrix of 40,000 columns. Becuase there would be memory issues if I use the whole matrix at a time, I splitted the matrix into submatrix of 10,000 columns and then calculate the pairwise correlation of different submatrices. There are altogether 4 submatrices, so I need to calculate the pearson

Hi, I have samba-3.0.23d-1tr on a trustix 3.0 system. This samba was joined to a win 2k3 domain and it works perfect for lot of months. Now I can access only to tmp share, and samba server is sometimes slow to expose all shares. If I launch wbinfo ?u or wbinfo ?g, I still see the users/group from win2k3 server, but in the log of my winxp client (whose name is Euro15), I see: [2006/12/27

Hello, I have several questions around matrices size limitation: can i create a matrix with 700000 rows? does it depends on the number of columns? if so can Is there a way to ask to R, given the number of columns, the max number of rows I can have? I need in fact to do regression prediction on a huge matrix (700000x1000)ca. ... I will probably have to decompose it on several

I've done all the googling I can on this, and have come to the conclusion that a Grandstream BT101 can be abused to be a door phone. Could someone with access to one, confirm that the following is possible? Researched: 1. When set to auto-answer, dialing the phone will result in a short beep and instant speaker-phone connection. 2. When pressing the "message" button while

Does anyone have something like tapply that is extremely fast for matrices when there is a very large number of levels of the grouping variable? I'm referring to, for example, tapply(x, grouping.variable, function.operating.on.submatrix) where x is a matrix and the submatrix is a subset of the rows of x. The grouping variable's length equals the number of rows of x. -- Frank E
