Create new string of same length as entry in dataframe
I suspect that this is simple, but thanks in advance for any advice... I have a dataframe, t2: V1 V2 aaa 3 aaaa 4 aaaaaa 6 a 1 aa 2 V2 is the length of the string in V1 using nchar(as.character(t1$V1)) I'd like to create a third column, that contains a string of the length of V2, but containing an alternate text, e.g. V1 V2 V3

How to repeat a procedure
Hello, 1. After I generate a 100x50 matrix by x3<-matrix(0,100,50);for (i in 1:100) {x1<-rpois(50, mu[i]);x2<-x1; x2[runif(50)<.01]<-0; x3[i,]<-x2}, 2. I want to calculate means and sample variances of each row and create a new matrix 100x2; 3. I then want to repeat above procedure 500 times so that eventually I will have 500 100x2 matrices. Would someone mind helping me to

Creating Multiple Repeating samples and Cross Correlating them.
I'm having a lot of trouble getting this done and nothing I've written has been remotely successful. Basically I have about 64 binary data sets stored as vectors, with 72900 entries in each. I am not very familiar with cross correlations, but I was advised that I should create 1000 randomized date sets (used sample() for that) to use as a control, then compare the cross correlation of my

correlating matrices
Hi, thank you for taking the time and reading my question. My question is twofold: 1. I have several matrices with variables and one matrix with water levels. I want to predict the water level with the data in the other matrices. Basically, * mod<-lm(matrix1 ~ matrix2+matrix3)* ( What looks like a minus is meant to be the wiggly minus.) Of course I could dissemble the matrices and paste

Problem correlating TSC read from domU with Xentrace's TSC
Hi, I am trying to correlating performance issue in guest VM with the scheduling trace from Xentrace. User-mode application in guest VM periodically dump APIC ID and RDTSC into trace. I also start Xentrace in Dom0 during the same period. However, I notice that range of TSC values report both trace is completely disjointed. TSC values from Xentrace is always greater than what guest VM see, even

Help with beanplot fromatting
Dear Helpful R Users, I am graphing some data using the beanplot, but I am having trouble getting the output I desire. I have five tanks (A-E) and 2 groups for each tank grp1 or grp2, except tank C where there is only grp1. (I only changed the grouprep to "C grp1" for the example) When I plot them, I would like A B C(only grp1 - half of the bean plot) then D and E (as full beans).

Analyzing and correlating Dovecot with Postfix logs
Hi All, I was wondering if anyone knows what are best practices for correlating logs between Postfix and Dovecot ? I am having setup with postfix + amavisd + spamassassin + dovecot and everything looks like a charm for few years now. However, when e-mail arrives to my system, postfix is sending it to amavisd on port 10024, which is returning back to postfix on 10025, and postfix is then

Calculating sum of squares deviation between 2 similar matrices
Hi all, I've got clusters and would like to match individual records to each cluster based on a sum of squares deviation. For each cluster and individual, I've got 50 variables to use (measured in the same way). Matrix 1 is individuals and is 25000x50. Matrix 2 is the cluster centroids and is 100x50. The same variables are found in each matrix in the same order. I'd like to

ustack() issues && correlating SIGSEGV activ ity?
Hi Ryan, > Does anyone happen to know why the ustack() doesn''t show lex, > yak, main > and _start? A quick look with the source browser seems to indicate that _rt_boot is code executed very early in the lifetime of your process by ld.so.1. What seems to be happening is that ld.so.1 has allocated some memory before DTrace got control of your process - long before main() was
