similar to: Website, book, paper, etc. that shows example plots of distributions?

I am a beginner in R, so please don't step on me if this is too simple. I have two data sets datax and datay for which I created a qqplot qqplot(datax,datay) but now I want a line that indicates the perfect match so that I can see how much the plot diverts from the ideal. This ideal however is not normal, so I think qqnorm and qqline cannot be applied. Perhaps you can help? Ralf

Hi, is there a way to take a data frame with 100+ columns and large data set to do efficient exploratory analysis in R with pairs? I find using pairs on the whole matrix is slow and the resulting matrix is tiny. Also the variable of interest for me is a binary var Y or N . Is there an efficient way to graphically view many variable relationships that does not look teeny ? I could do

I have Acts_As_Taggable Plugin working. I have a HR controller and a sales controller. I have a document in hr tagged whitepaper and a differnent document in sales tagged whitepaper when I am in hr I see the hr document tagged with whitepaper and not the sale document (what I want). but if I click on the tag whitepaper I return two documents, hr and sales. I just want to return the hr document

For a financial data set with large variance, I'm trying to find the outlier threshold of one variable "x" over a two year period. I qqplot(x2001, x2002) and found a normal distribution. The latter part of the normal distribution did not look linear though. Is there a suitable method in R to find the outlier threshold of this variable from 2001 and 2002 in R?

Hi All, I am trying to plot 4 graphs on to 1 page using layout(...), or par(mfcol = c(...)); with the function QQplot from the package PerformanceAnalytics. The problem is that, no matter what order I use, it only plots 3 graphs on to 1 page and the last QQplot is shunted to the next page. Also, this only happens to the QQplot, i.e. there is no problem with 4 Histograms. set.seed(1033) data

I've seen this asked, but never fully answered.  Is it possible to plot stacked histograms in R? I have four data sets that I would like to show combined vertically in histogram format.  Is this possible?  Thank you for any feedback you can provide. P.S. I know I can show the four sets side by side, but I want to combine them, but still uniquely identify each.   Thanks again.

Attached is a 500KB read-only .doc file with a Samba and Terminal Server whitepaper. I have tried to hit every known issue and all available workarounds. If anyone has comments or suggestions, let me know. JT has it, so it should end up in the next How-To. Sorry about the file format, but the .pdf was 2.5MB, which I thought was too big to post.

I have summary statistics from many sets (10,000's) of near-normal continuous data. From previously generated QQplots of these data I can visually see that most of them are normal with a few which are not normal. I have the raw data for a few (700) of these sets. I have applied several tests of normality, skew, and kurtosis to these sets to see which test might yield a parameter which

Hello, I am analysing several samples whose sizes are from 9 to 110. I would like to test their distribution with R, whether they are normal or not. I wonder which test for normality from R should I use . Thank you for help.

Dear R-ers, I don't understand the following, maybe someone will help me explain: > setClasss('A') [1] "A" > new('a') Error in new("a") : trying to generate an object from a virtual class ("a") > setClass('b', contains='a') [1] "b" > new('b') An object of class ?b? <S4 Type Object> In what

Good Night I made different test to check normality and multinormality in my dataset, but I don´t know which test is better. To verify univariate normality I checked: shapiro.test, cvm.test, ad.test, lillie.test, sf.test or jaque.bera.test and To verify multivariate normal distribution I use mardia, mvShapiro.Test, mvsf, mshapiro.test, mvnorm.e. I have a dataset with almost 1000 data and 9

Hi all, i have read in the * whitepaper the following: "s: The "start" extension. A call which does not have digits associated with it (for example, a loopstart analog line) begins at the "s" extension." I think this means the s extension will be execute when the phone is picked up. But when i pick up the phone the s extension will be never executed. Whats wrong

Hi all, I''m not able to use shorewall for manage a bridge.

I have test many configuration (managing hosts,interfaces,zones files), but I get always the same error. Have I to compile a new kernel? With which

Dear R community. I am using the identify() function to identify outliers in my dataset. This is the code I am using: #################################################################### # Function to allow identifying points in the QQ plot (by mouseclicking) qqInteractive <- function(..., IDENTIFY = TRUE) { qqplot(...) -> X abline(a=0,b=1) if(IDENTIFY) return(identify(X))

In the subdivision where I live, we have a well that time to time has problems. Currently, our trustees call me, I take a message, and then call the people on our "phone calling tree" and give them the message. They, in turn, pass the message on to the rest of the residents. We have a few problems with the way this works -- people don't bother to relay the message, or,

Hello How to compare  two statistical histograms? How i can know if these histograms are equivalent or not??   Regards [[alternative HTML version deleted]]

TL;DR: At Google we use a call tracing system called XRay which inserts patchable instrumentation points into function entries and exits. If the community is interested, we'd like to contribute this system to the LLVM project. Many more details are contained in the whitepaper at: https://storage.googleapis.com/xray-downloads/whitepaper/XRayAFunctionCallTracingSystem.pdf Who's
