Hi, I have a data frame with one column and several rows of the form. "Peak Usage : init:2359296, used:15859328, committed:15892480, max:50331648Current Usage : init:2359296, used:15857920, committed:15892480, max:50331648|-------------------|" I tested the regex Current.*?[\|] in an online tester which greedily matches upto the first 'pipe' character Current

Hi, I would like to understand how to draw a graph to find out the average memory used by a single httpd process given these details collected over a period of several days. I code R but this is about a method to find an average memory utilization. I believe I have enough data. How should I statistically calculate this ? The figures inside braces are the total httpd processes at

Hi, I haven't tried the code yet. Is there a way to parse this data using R and create bar plots so that each program's 'RAM used' figures are grouped together. So 'uuidd' bars will be together. The data will have about 50 sets. So if there are 100 processes each will have about 50 bars. What is the recommended way to graph these big barplots ? I am looking

Hi, I have been using R for a few months and I have this working code. Don't seen any problem but this takes a long time. So if I have about 30000 rows it takes a few minutes. If I have 100000 it does not seem to complete. Original Data: Proto Recv-Q Send-Q Local-Address Foreign-Address State tcp 0 0 172.20.100.2:60255

Hi, This is not a sophisticated statistics question as the subject suggests. But I am logging data - number of user sessions in a web application - before and after new users are migrated. I use R to graph but I am looking for a way to quantify the growth in the number of user sessions. As more users are now using the web application there is a growth. What is the way to measure this

Yes. I tried that already. Not straightforward. data <- read.csv("20_newsgroups.csv",fill=TRUE,as.is=T,header=F, quote="", sep=",", encoding="UTF-8") This line does read it haphazardly. The emails in the column are split into multiple columns and there are several columns with just ?NA?. Totally 202 columns. And then I removed columns with NA?s and

Hi, Reading http://ssc.wisc.edu/~ahanna/20_newsgroups.csv after downloading it using data <- read.csv("20_newsgroups.csv",header=TRUE) throws this. Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : EOF within quoted string So, for example, the first line in the file is this. This column contains only such text. Is there a way read it ?

Big news for all Java programmers out there. Now you can use Cucumber with pure Java! That''s right, you don''t have to write a single line of Ruby! (1) All of your step definitions can be written as annotated methods in POJOs (Plain Old Java Objects). To get a taste of what this looks like, check out the simple example in the cucumber_java project on GitHub: * README for

Hi, I am again asking a generic question and the general response for such questions is cold. I am a beginner but use and write simple R scripts. I am looking for some ideas to calculate the confidence intervals based on this excerpt from the paper. Moreover it would help if someone points to material to read about degrees of freedom and any related concepts. Thanks,

Hi, plot(xc, yc, type="l", ylim=c(0,50), xlim=c(0,50), lwd=2, xlab="M", ylab="seconds") abline(a=-think, b=cpustime, lty="dashed", col="red") abline( 2.2, 0, lty="dashed", col = "red") This draws a response time curve an asymptote and a horizontal line. How do I draw a line from the intersection of the asymptote and

Hi, I plot no: of bytes against time and find the distribution curve using R. These bytes are sent from the client to the server. Is there a way to generate bytes randomly using R according to a distribution ? I would like to send these bytes to the server. Hope I am not misguided here. My goal is to simulate a certain distribution of bytes. Thanks, Mohan DISCLAIMER:\

Hi, Is there a way to calculate variance directly by specifying confidence interval using R ? I am specifically asking because I wanted to investigate how this could be useful for project schedule variance calculation. Moreover I am interested in using R for monte carlo simulation as well and any simple examples would help. I read that project schedules would benefit from this.

Hi, I am looking for some assistance with these requirements. We are trying to simulate web requests to hit a web applications. Let's assume I have a url to hit that requires a username and password. 1. These web requests should have exponential inter arrival times. 2. Generate self-similar traffic. I am not very sure about the properties of this traffic. Is Variance Time plot

Hi, I have a hierarchy of such classes. Subject has a list of measurements. Let assume I have a list of such 'Subject' RC's. Can I use dplyr to navigate from Subject to the list of measurement RC's and filter and group data ? dplyr should be able to call the methods on these RC's to operate on the data structure ? I tried to coerce the list of RC's into a data frame

Hi Everyone I am considering learning Java. There have been well publicized Java security incidents recently that make me not want to learn it. However it's in Centos and I trust Centos, are the concerns in the media blown out of proportion ? -Patrick

Hi LLVM developers, I have successfully installed LLVM 2.9 on an ubuntu linux box, with a LLVM-based frontend support of gcc and g++. After installing successfully vmkit I have tried running my java applications, but it failed. I have installed the latest stable release of vmkit (0.29) using the introduction text of the LLVM website. The application does consist of two programs. The first
