histogram question
hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300)) gives a histogram with "touching bars" hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000)) gives a histogram with space between the bars. is there a way to control the space betweent he bars easily? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at

factor always have type integer
typeof applied to a factor always seems to return "integer", independently of the type of the levels. This has a strange side effect. When a variable is "imported" into a data frame, its type changes. character variables automatically are converted to factors when imported into data frames. Here is an example: > v1<-1:3 >

Statconnector and Excel
Hi, I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both. However I would like to display the r-generated data in an Excel sheet as an array but I don't manage. Here is an example of my source: Sub doR() Call RInterface.StartRServer Call RInterface.RRun("library(mdnn)") Call

A Question on lowess() function
Hi, all, I want to use lowess(x, y) where x and y are vectors of length of 4000+. In fact, x and y are log of some vectors. So, some of the elements are NaN. lowess() can not take away those elements then do the fitting. It will give the error message and do nothing. 1. Can anybody tell me how to get rid of those NaN's and use lowess()? 2. How to get the LOWESS fitting values for any

Local parameter calculation
Dear all, I am a newbie in R. I encounter a problem as follows. I have 2 vectors X and Y that have a equal length of several thousand. I see Y as the function of X. Both of them are random. X is not arrranged in any order. Of course, I do plot(X,Y). Now, I want to use a sliding narrow window to run over each X, then calculate the variances within that window. Anyone knows easy way in R to do

about the function order()
Dear all, I have recently experienced something with the function order I cannot explain: The help(order) (which I admit having overlooked before) rises even more my confusion... The following lines made me think order() was returning the 'order' each value in a vector would take when sorted. > a <- c(4.1, 3.2, 6.1) > order(a) [1] 2 1 3 Doing > plot(a,

New unique name
In some languages there is a function gensym() which returns a new unique name (in the current environment). This is quite helpful when one has to do temporary assignments.

R as a library
I would like to write a stand-alone application (in C) using R's statistical and graphical capabilities. To make it more challenging I would have to do it using Windows 2000 platform. I seem to remember that R can be compiled into a library of subroutines and linked to an external program. Is this true or is my memory playing tricks on me? I scanned the FAQs and the "extensions"
