similar to: Extracting data from a list of matrices

Hi, netters, This is probably a rookie question but I couldn't find the answer after hours of searching and trying. Suppose there'a a dataframe M: x y 10 A 13 B 8 A 11 A I want to locate the rows where x >=10 and y="A". I know how to do it to vectors by using which, but how to do it with the dataframe? Thank you very much! Zhihua Li

Hi Alex, Would you recommend any specific link in respect on how to compile in debug mode? I downloaded the Mac OS version on the website so I did not compile anything. I am sort of a rookie on bash but I should be able to figure my way around this. Also, is there any particular reason why this functionality is only available on debug mode? Thank you so much for the fast reply, was driving me

Hi Carlos, You can just download the source code from http://llvm.org/releases/download.html#2.9 and then read http://llvm.org/docs/GettingStarted.html which should tell you how to compile it.

I am producing 2X2 correlation matrices by a class variable. I need to extract a vector of correlation coefficients only. I am doing that in a loop (see below) but I am sure there would be a simpler way. Please help! > by(d1[,c(2,3)],d1[,1],cor) d1[, 1]: 1 c e c 1.0000000 0.1972309 e 0.1972309 1.0000000

Hi all, I have an object that looks (roughly) like the following: l <- list(a = matrix(rnorm(9), 3), b = matrix(rnorm(9), 3), c = matrix(rnorm(9), 3)) l$a[3,] <- sample(c("Message 1", "Message 2", "Message 3")) l$b[3,] <- sample(c("Message 1", "Message 2", "Message 3")) l$c[3,] <- sample(c("Message 1",

Hi Joey! Thanks I just replied your message on stack and I was actually looking into this right now. Is this the option? I just wanted to confirm: - make [-j] - The -j specifies the number of jobs (commands) to run simultaneously. This builds both LLVM and Clang for Debug+Asserts mode. The --enabled-optimized configure option is used to specify a Release build. The -j parameter is

I've just installed Redhat 8.0 + latest updates on a Intel PC and am trying to install the R 1.6.1-2 rpm but get the following: # rpm -i R-1.6.1-2.i386.rpm warning: R-1.6.1-2.i386.rpm: V3 DSA signature: NOKEY, key ID 97d3544e error: Failed dependencies: libtcl.so.0 is needed by R-1.6.1-2 libtk.so.0 is needed by R-1.6.1-2 What am I missing?

Hi, The -j option just says how many processes are started to parallelise the build. The default option is to build Debug+Asserts, so unless you add any extra arguments when you run './configure', you should be fine!

Hello List, I have a problem with the CA on my Puppetmaster. This Puppetmaster is connected to different Networks with different sub domainnames. The Puppet clients connecting via different Interfaces. There is no routing between subnets. Only one subnet can connect successfully. This is because the subject in the Certificate is the name of this subnet. All other clients get: Could not

Hi all, Running R 0.90.1 on a RH 6.1 system. Installation of the integrate_2.1-2 package went smoothly. My code contains a loop in which integrate() is called several times in each pass. I get a segmentation fault after what seems to be a random number of calls to integrate(). Debug output shows: Program received signal SIGSEGV, Segmentation fault. promiseArgs (el=0x40276414,

I have 2 matrices. One which contains a complete set of row combinations. Another which contains a subset of the first. What I would like to extract is the rows which are in the first but not repeated in the second. For instance if the following were my two matrices, A [,1] [,2] [,3] [,4] [1,] 1 2 3 4 [2,] 1 2 3 5 [3,] 1 2 3 6 [4,] 1 2 3

Hello, after an update I've got troubles with nut. It is not able to connect via usb to our UPS anymore. I dont know wether it is the nut update or the kernelupdate or both. In any case, it is difficult to get new rpms for CentOS. So if someone has an Idea, what I can try to solve this Problem: please help. Atached are relevant information.

Hi dear users, I try to split a matrix into a few matrices, for example, suppose that I have 1000X4 matrix from mvrnorm(1000,m,c) with m<-matrix(c(0,0,0,2),4,1) and c<-matrix(c(1.0,0.2,-0.5,0.3,0.2,1,0.2,-0.5,-0.5,0.2,1,0.2,0.3,-0.5,0.2,1),4,4,byrow=T) How to split the matrix into a. 2 matrices which the first one consists of the first 500 rows, and the second one consist of the

Dear All, Let a, b and c are?three matrices with same no. of column but different no. of row. a <- matrix(1, 1, 2) b <- matrix(2, 2, 2) c <- matrix(3, 3, 2) Could someone help me to combine these matrices together as a single matrix? Thank you Fir

There is probably a simple and obvious answer to this, so sorry for wasting your time... I have a matrix of predictions from an proportional odds model (using the polr function in MASS), so the columns are the probabilities of the responses, and the rows are the data points. I have another column with the observed responses, and I want to extract the probabilities for the observed responses. As

Dear R list I have an m * n matrix P and a vector V of length n containing indices for rows in P. For each of the m columns I want to extract the value in the row specified by V, and put these values into a new vector W of length n. At present I am doing this with a for.... loop, but I imagine there is a faster way that doesn?t involve loops. If anyone knows the way I would be most grateful.
