Averate memory usage trend
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

Memory usage bar plot
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

Functional Programming patterns
Hi,
'
Not specific to 'R'. I search for patterns and found
http://patternsinfp.wordpress.com/ which is too heavy for me. There is a
'Pragmatic Programmer' book on such patterns for Scala and Clojure. Is
there anything for R ?
I wanted to code this. Is there a functional pattern in R for multiple
'if' loops like this ?

Locating inefficient code
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.

Growth calculation
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

EOF within quoted string
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

EOF within quoted string
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 ?

Basic question about confidence intervals
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,

variate generation
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,

Variance with confidence interval
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.

Operating on RC in a list
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
