I would like to get a curve of normal distrubtion over the histogram. Something like the following (which obviously doesn't work; see attached example). maluj <- function() { vrhy=read.csv("pennies.csv",head=TRUE) hf=table(vrhy$HEADS) postscript("heads.eps",onefile=FALSE,width=4.134,height=3.445,pointsize=12) plot(hf,main="Frequency distribution of

Hi, how to do quickly equivalent of the following? counter = 0 for(i in 1:length(data$S2)) { if(!is.na(data$S2[i])) { counter = counter + 1 } } I have imagined something like length(x,na.rm=TRUE). How can I get values usually taken from tables like z-score, values of t distribution etc.? I could not find them among values mentioned in info file. Thanks, Matej -- Matej Cepl,

Hi, I have this table (BTW, published by FBI and representing age distribution of the WTC tragedy victims): "LABEL" "FREQ" "MIDPOINT" "1" "Infant (under 1)" 0 "2" "1 to 4" 5 "3" "5 to 8" 1 "4" "9 to 12" 3 "5" "13 to 16" 0 "6" "17 to

I have probably misunderstood something (again :-(): > CEMPLOY<-TEMPLOY[!is.na(TEMPLOY)] > sum(CEMPLOY^2/length(CEMPLOY))-mean(CEMPLOY)^2 [1] 30877.28 > var(TEMPLOY,na.rm=TRUE) [1] 30981.25 Could anybody tell me, what's going on? I suppose that var=sum(x^2/N)-xbar^2 or what did I enter wrong? Thanks Matej -- Matej Cepl, matej at ceplovi.cz, Finger: 89EF 4BC6 288A

How do I get non-squared correlation coefficient in some more sensible way than sqrt(summary(lm(y~x))$r.squared)?

Hi, I have probably overlooked something obvious, but could anybody help me with following, please? Trying to make regression analysis. I have a huge dataframe with results from National Opinion Survey on Crime and Justice (www.abacon.com/fox/) with two variables G5 and N3 which are imported to R as ordered factors: > levels(noscj$G5) [1] "Strongly agree" "Agree"

Hi, I have a question, how to most properly select set of cities which would be as similar as possible in some particular variables with the City of Boston (which I use as my base line). I thought about ordering cities by sum of ((differences between value of that particular variable for that particular city and the value of same variable for Boston) divided by the standard deviation of the

Hi, I've heard somewhere that it is possible to store inside .ogg files text streams and thus it should be possible to store lyrics for the sond directly in the file. Is it true? Could anybody point me towards some code how to do it (Python preferable, but not required)? Is there any documentation for text streams in .ogg files? Thanks for any reply, Mat?j -- GPG Finger: 89EF 4BC6 288A

Hi, I have got to my hands an excellent book by Michael J. Crawley ``Statistical Computing: An Introduction to Data Analysis using S-Plus'' (John Wiley & Sons, Ltd, ISBN 0-471-56040-5). Its beauty for me is in the fact, that it is more of ``An Introduction to Data Analysis'' than ``using S-Plus'', but I guess that it may be of interest for many others. Most of the

Hi all In two days, I am giving a small, informal workshop in our Department about using R. Initially, it was just for statistician, but surprisingly (to me anyhow) many mathematicians are also coming who have a MATLAB background. They are coming at the Workshop from a teaching perspective. They are considering using R to avoid licensing issues with MATLAB. One thing they were hoping me to

Hi, I understand that I can find t-test for the significance of the correlation coefficient on sample to population, but is there way how to make this test for more than one pair of variables together as easily as I can make a correlation matrix for more variables with cor(cbind(A,B,C,D))?

Hi, I would love to make multiple histograms transposed one on another in order to show relation between the sets. I tried to write a function like this, but R tells me, that I cannot use add=FALSE in high-level commands. That's nice but I am supposed to do? rm(list=ls()) # what's wrong with underscore? #getwd("/home/matej/docs/skola/stat\_anal-cj3534/assign01/")

I just detected R and have, after browsing the manual, one question: I look for quite a lot of time for graphical software which allows to plot data from a table or external file _with the axes of the coordinate system changed_, i.e. the x-axis should run from top left to bottom left, and the y-axis from top-left to top-right. It is of no use to interchange the rows in the table, the

Hi, I have a SPSS datafile which is used for my textbook in the statistics (and which is available on http://abacon.com/fox/s6720p2.sav, but it is originally from ICPSR). When I opened it with SPSS 10 and run Frequencies on it I have got 979 valid data a 27 missing. However, see below (unfortunately, I have used R in preparation of my homework, which caused me an error on this): >

Without having dug into the details, it could be that one could update the parser by making a 'return' a keyword and require it to be followed by a parenthesis that optionally contains an expression followed by end of statement (newline or semicolon). Such a "promotion" of the 'return' statement seems backward compatible and would end up throwing syntax errors on:
