Sgeostat module
Dear Users, I use Sgeostat to calculate co variogram (function est.variogram with two variables). If i inverse the 2 variables in the functions, the co variogram change! Normaly it is symmetric, isn't it? Someone could me explain why, or give me an idea to calculate co variogram in a easy way...

plotting overlapping data points
I am just learning to use R. The data from my current project are integer-valued. I am able to create scatterplots, but I would like to have some indication on the plots when multiple data points overlap at the same x-y coordinate. SPSS uses 'petals', and other packages use jitter. Are there similar options in R? I have not been able to find any in the documentation. Thanks very much,

Importing many files
Hello Cracks, we want to import 10 x 365 files containing each 7 variables with 1211 rows. The filenames end with numbers from 1 to 365. We tried a for loop to import using read.table but we couldn't create the r objects within the loop. We want each file in an own r-objekt (matrix). Does anyone know what can be done?

Quick question!
Thanks very much to all who answered my question yesterday on loops. Just a further quick question: If I have this: for(i in 1:n) { subset <- data[which(data$id==i),] which returns the rows where I have the variable ID=1, how can I tell the same statement to return just column Y where ID=i? I have tried this for(i in 1:n) { subset <- data[which(data$id==i),data$Y] but it

Re: R: Mailing Lists
Is it true that append=T does not work in assignTable() in RMySQL ? More specifically: I cannot append a data.frame to an existing table in a MySQL database, although I can use the same data.frame to create a new table. Even more specifically: > assignTable(con,"employee",dita,append=T) Error in execStatement.MySQLConnection(con, statement, ...) : RS-DBI driver: (could not

Help for Linear Discriminant Analysis
Dear colleague, I'd like to compute linear discriminant analysis, using R. In the book Modern applied statistic with Splus (Venables & Ripley, p. 396), lda function is used. Could you tell me where I can find this function? At what site, can I download this library ? Thank for your help.

No subject
Hi, I'm a new R users (although I have a little experience with S+). I am using the latest version (1.4.1) of R on a Windows 2000 system. I have obtained several of the additional R packages ("modules") and would like to know how to permanently install them. What I am after is something similar to the following in S+ > .First <- function() { module("module_name")

overlay plots
Hi all! I new to R (I don't know anything about S+ either!) I've a simple question: How do I generate overlay plots in R? So far as I can see the plot(x, y) operator will only give me one graph and the plot(x ~ y + z) will give me 2 separate plots. Is there an easy way to overlay or am I missing the obvious? Any help welcome. Gerard Keogh The information in this email, and any

Opening all files in a directory
Is there any way that R can be programmed so that it will cycle through all files in a directory without having to define file names? The reason I ask is because I will have about 50-100 files in a directory which will be randomly named. ie: MIDEX, OACES-CO2, ODEN91, etc... If not...are there any languages out there that will do this sort of things? Or is there another method you could

I have my data in a postgresql database, and I manage to get them into R as a dataframe with columns for respectively: Name of the analysed m2, Name of the species, coverage of species in the square in %.

RMySQL fetch defaults to N=500?
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

URGENT Help required
I've the following problem: The below function runs a loop with regression analysis and stores F-Stat in a matrix. When I call the matrix elements (models[i,j]) in the function I get proper results, but when I try to call the same elements outside the function the matrix appears to be empty e.g when I call compt inside the function I get: 5 but when I call it outside I get: 1.
