I've got a data set with integer codes from 0--3. I'd like a histogram with a single bar for 0, 1, 2 and 3. I'd like each of the 4 bars centered over a label. hist(mydata, breaks=4, main="Simulation") gives me three bars. The best I've been able to do is do something like print(hist((wexp), breaks=25, main="Simulation")) This gives me something

I'm doing a study where people place a deck of cards in a certain order. It's sufficient to assume that their colors & each has a number (it's actually about attributes of hobbies). I'd like to look for patterns in how they've arranged the deck. For each subject I have a list like 3,5,2,4,1, indicating that (s)he chose 3 first, then 5, then 2. . . . I think what I first

I've got a graph with really long labels. I've tried decreasing the font size, but they're still getting truncated. I've RTFMed & it seems that mgp should have something to do with this, but I can't make it work. I need about 2-3x as much space for labels as is available by default (or on the example below). boxplot(split(ranks,c(1:25)), names=items, horizontal=F)

It appears that fetch() gets only the first 500 rows by default. I don't see this in the documentation, but timeinfo <- fetch(rs) gets only 500 rows where timeinfo <- fetch(rs,n=-1) gets (correctly) 736 for the same query. Is this an undocumented feature? I played with this data for an alarming amount of time before I realized that I was missing a third of the data. I

I'm an R novice and my colleagues are about to convince me to get my data into SPSS, which will presumably be easier for someone who doesn't live in R to point and click his way into some kind of analysis that might be meaningful. I've got two groups of subjects (classkey in the table below). They've each received several different treatments. One measure is a 1-7 rating taken

I've got a background in computer science & have been using Linux for nearly a decade. I'm working on a Ph.D. in education and technology and I essentially live in emacs and do all of my writing in LaTeX. To me R seems like the perfect stats package. Unfortunately, the learning curve is killing me. I feel like that if I'd waded through pulling down menus in SPSS or SAS I could

Hello, I have a data set that needs to be combined so that rows are summed by a group based on a certain variable. I'm pretty sure rowsum() or rowsums() can do this but it's difficult for me to figure out how it will work for my data based on the examples I've read. My data are structured like this: Plot SizeClass Stems 12 Class3 1 12 Class4

Another naive stats question. I'm trying to better understand what boxplots are telling me. I think what I see is the median and the boundaries of the 1st and 3rd quartiles. The whiskers represent the range of the data unless there are points which are outside "range" (default: 1.5) times the distance from the median to that quartile. Is that right? I've read the

Thanks for all the help on my previous histogram problem. I intend to summarize the solutions back to the list Real Soon Now, but first, I've got another problem. I've made a bar chart that reports means. I'd like to put the number of observations on top of each bar. Here's what I've got: barplot((subset$x), col=grey(.5), ylab="Mean Engagement

Hi, Please advice on what type of graph can be used to display the following data set. I have the following: Name Class a Class 1 a Class4 b Class2 b Class1 d Class3 d Class5 e Class4 e Class2 So each entry in name can belong to more than one class. I want to represent the data as to see where

Hello, i'm a french student of medical oncology and i'm working on breast cancer. I have a variable with the histologic type of tumor wich is between 1 and 5. I use as.factor function to make some variable with level between 1 and 5. When i put it in the cox model i have only the level between 2 and 5. The level 1 doesn't appear. I think i have to change the number of level but i

Dear All, After having overcome the issue of legends (thanks, Thierry, once more), I am trying to use facetting, but here also I can not find how to do this. I do not want to use qplot, but rather the more flexible options. However, it seems I am doing still something pretty stupid, because I always get an error, even if it seems I am doing everything like the examples. My code is below.

Hi, I'm working with Version 1.9.0 (2004-04-12) on Windows 98/NT/2000 where I found the following wrong (?) behavior of setValidity(). I already mentioned this on the R-help list (2004-06-11, was "setValidity changes Extends?") , but as I got no answer I tried to figure out what's happening. Well, setValidity() behaves not as I would expect (something about the

Hello, I have a question concerning the R-function chisq.test. For example, I have some count data which can be categorized as follows class1: 15 observations class2: 0 observations class3: 3 observations class4: 4 observations I would like to test the hypothesis whether the population probabilities are all equal (=> Test for discrete uniform distribution) If you have a small sample size

Hi, I have a question about running multiple in regressions in R and then storing the coefficients. I have a large dataset with several variables, one of which is a state variable, coded 1-50 for each state. I'd like to run a regression of 28 select variables on the remaining 27 variables of the dataset (there are 55 variables total), and specific for each state, ie run a regression of

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

Hi I share my bandwith (adsl 512/128) between 12 users. I set up simple qos script for incoming (IMQ) and outgoing traffic using htb in root, 4 classess and esfq qdisc at leafs. Interactive traffic goeas to class1 , http,mail etc. to class2, p2p, ftp to class3, and rest to class4. Classess divide link in proportion 20% (prio 1), 40% (prio 2), 20% (prio 3) ,20% (prio 4) This works

Here is the setup: Dell 6250, Quad Proc P3 500Mhz. Digium Single Span T1 card. System has 71 sip peers/users. All calls are G729; we have 10 licenses. All calls follow this path: UA -> Asterisk -> Digium PRI -> Class4/5 switch. The switch dictates if it should go out local PRI for local termination or out PRI to our Cisco AS5300 for LD termination. Our biggest problem is echo.

Hi, I run R 2.10.1 under ubuntu 10.04 LTS (Lucid Lynx) and klaR version 0.6-4. I compute a model over a 2 classes dataset (composed of 700 examples). To that aim, I use the function NaiveBayes provided in the package klaR. When I then use the prediction function : predict(my_model, new_data). I get the following warning : "In FUN(1:747[[747L]], ...) : Numerical 0 probability with
