Hello, I am trying to learn how to create a simulated dataset of a forest stand: I must simulate 10 stands, for each of the stands I have been creating a random number of trees. For each tree I should create a random diameter. The problem I have is that I cannot use a matrix because the length of the three items is different. I was trying with list but I have no clue on how to make a dataset out

My name is Giovanna and I am a PhD student in Norway. I am a beginner with statistics and R, hence my ignorance. Apologies from now..... I have been collecting data on time performances of 5 subjects using a 1:3 scale tower yarder. The task was consisting in yarding 5 small logs placed on permanently marked course. Four subjects had different previous experiences (None, Some) and the fifth was a

Dear All, In the last few days I started using the last version of R as I encountered a problem with R1.9 and the use of RWinEdt, however the problem shows with R2.01 as well. More precisely 1. I install R2.01 after removing old verions of R 2. I Install RWinEdt package versione RWinEdt_1.6-2 and SWinRegistry_0.3-2 and everything seems fine 3. I recall the RWinEdt library (library(RWinEdt)) and

Hello! When I tried to call Front41 in R, I met some problem.

Dear All, I have a database of 200 observations named myD. In the dataframe there are a column named code (with codes varying from 1 to 77), a column named "prevalence" with some quantitative measurements are given and an column named Pr_mean, with no values. I would like to set a cycle to compute the average of prevalence values for each different code and store the averages under the

Dear R helpers, I'm using R2.2 under windows XP professional on a Dell double processor workstation. I have a large (29Mb) workspace that I'm trying to load both, by double clicking and by direct load. The message I get is "Bad restore file magic number (file may be corrupted)...". I believe that this is a consequence of a huge spike in the electrical system that my voltage

Hi, i have to optimise a function f(a,b), with a, b vectors in R^d such that a and b are orthogonal, that is a'b=0. Anybody has a suggestion?

I'm collaborating with and electronic musician to experiment on the production of music from number sequences. As I'm an R user I started playing around with the sound library and I found it very useful. However there are several things I do not understand (I'm not an expert in acustic nor audio signal treatment). The first thing I'd like to understand is: let s be a normalized

Imagine that I have a large number of points (given by coordinates x and y) that vary in density per space. For the purpose of demonstration it could be generated like this: s <- data.frame(x=runif(10000,0,900),y=runif(10000,0,900)); plot(s) I want to create polygons around the points where point density is greater than a selected threshold (for example, by using krieging or equivalent

Dear R users, I would like to inform you that everything of the "micEcon" package that is related to Stochastic Frontier Analysis (SFA) has been moved to the "frontier" package, because this is a more appropriate place for the functions "front41WriteInput", "front41ReadOutput", and "front41Est", and the corresponding (S3) methods. The data

Hi, I would like to compute the autocorrelation time from my 2-D time series, but I cannot find how to do using R. I have found the fucntion acf and acf plot, but how can find the autocorrelation time? thanks -- View this message in context: http://r.789695.n4.nabble.com/help-on-autocorrealtion-time-tp2065129p2065129.html Sent from the R help mailing list archive at Nabble.com.

Dear all, For my research I need to perform a Levene's test on my data.I have not large experience with this test and with R,so I have some problems to use the leveneTest function. I read some previous posts on this topic but I cannot understand what I have to do. I have a five-columns data frame organised in the following way: number of observation, number of subject, score, type of
