sapply and loop
Dear all, I am doing 200 times simulation. For each time, I generate a matrix and define some function on this matrix to get a 6 dimension vector as my results. As the loop should be slow, I generate 200 matrice first, and save them into a list named ma, then I define zz<-sapply(ma, myfunction) To my surprise, It almost costs me the same time to get my results if I directly use a loop

run R under linux
Dear all, Our department uses the linux system and we are not allowed to submit job directly. We must make a batch to submit through "qmon". so, I make a foo.sh file, which only contains one line: nohup R --vanilla < foo.txt > foo.results foo is all my codes. It is a simulation of 200 times. I set the seed at the beginning. It is to estimate the success probability, which is

Estimate of variance and prediction for multiple linear regression
Hi, everyone, Night. I have three questions about multiple linear regression in R. Q1: y=rnorm(10,mean=5) x1=rnorm(10,mean=2) x2=rnorm(10) lin=lm(y~x1+x2) summary(lin) ## In the summary, 'Residual standard error: 1.017 on 7 degrees of freedom', 1.017 is the estimate of the constance variance? Q2: beta0=lin$coefficients[1] beta1=lin$coefficients[2] beta2=lin$coefficients[3]

Don't Understand Error Entry
I am using dovecot-0.99.11-8.EL4 on my system and decided to check the logs since I just took over as the administrator on this system and I noticed the same error entry over and over in the logs. I went to /var/log/dovecot.err and see: imap(rangry): May 22 13:33:31 Error: Error parsing IMAP envelope: "Thu, 20 Apr 2006 10:10:01 -0400" "Re: Hi there I have a question"

Renaming Journey and avoiding libraries with common noun names
Hi all, I know this is a long shot, but could renaming the "Journey" module please be considered by those in a position to support it? I''ve written an issue on this in the journey repo also: https://github.com/rails/journey/issues/49 Essentially our project has a model named Journey, the same as Rails 3.2''s new routing driver. As a consequence we can no longer

what's the R code for wavelet decomposition (Haar transformation)?
Dear all, Using R function "dwt", it seems that I cannot specify the wavelet transformation like Haar. What's the R code for wavelet decomposition which allows me to specify Haar wavelet transformation? Of course, if it can include "db2", that is even better. In general, I want an R function like matlab code "dwt". Thanks in advance! Zhen Li

command line limit under unix?
Dear all, I have made my testing program to run successfully under unix in the background. However, my simulation work does not work. I read the foo.results file, I found it only have part of my code and not any output I want. Is there any line limit? My code is nearly 400 line. I can cut some of them, but I want to know whether there is any limit or exactly the number of limit is. Thanks.

Independent variables omitted in lm and glm
Dear List, Some independent variable were missing in calculation using lm and glm (gaussian). (X= Y1+Y2+…..+Y16, Independent number: 16 variable) However, those variables did work well in cor(X, Y) respectively. str(dataframe) was also run to ensure that the variables were all numbers. Moreover, the missing variables were different in lm and glm. In lm, 3 factors were not taken into

sort the values of members and obtain their ranks within groups
Dear all, I would like to sort the values of "member" for each group, and obtain a variable to indicate its rank within the group. For example, we have original dataset as follows: df <- data.frame(group = c(rep(1, 3), rep(5, 3)), member = c(30, 10, 22, 21, 44, 15)) group member 1 1 30 2 1 10 3 1 22 4 5 21 5 5 44 6 5 15 After

How to use the pass 'Unroll and Jam'
Dear LLVM developers, Recently I want to try the pass '-loop-unroll-and-jam' to observe how the IR is transformed, but I don't see the IR changed after doing the following steps. Here are the details for preparing my experiment and I have tried the LLVM 6, 7 and 8: 1) Simple 2D array source code (loop.c) is given ``` #define M 32768 #define N 32768 double a[M][N], b[M][N],

Question on Rprof(); was: Re: sapply and loop
Yes. It should have something to do with read/write permissions, but it is not clear how it happens. I can write file to C drive using R. I usually write my results matrix to a txt file in C drive. For Rprof(), the boot.out file can be created, but only with one line sample.interval=20000 The situation is the same even if I specify the directory to the D drive,where I have the full

why vlan tag is retained in promisc mode
In current Crossbow''s implementation, vlan tag seems to be unconditionally retained for promisc mode listener even when MAC_OPEN_FLAGS_TAG_DISABLE is not specified. I saw comments in mac_rx_deliver() saying that this is deliberately designed like this. I''m wondering why we design it like this (choose not to respect MAC_OPEN_FLAGS_TAG_DISABLE flag for promisc mode listener)? Or
