similar to: overlay plots

Hello again! thanks to all who helped with overlay plots - v. easy in the end. Anyway, another new(ba)bee type question - the gurus will cringe I'm sure! Q. simple R function mm <- function (u) { x <- u$GDP x m <- mean(x) m } When the function is called the vector "x" does not get printed from within the function, but the mean value "m" does, why? I

Hi all! I'm sure this must have been asked many times before but here goes anyway. I'm looking for a kalman filter in R for ar(i)ma time series. I'm sure there must be one around but it does not seem to be in either ts or tseries packages? Any suggestions welcome.

I have just installed R on a Windows NT system. Unfortunately I am unable to open any of the data files I wish to work with. I have tried using read.table and scan and to the best of my knowledge am using the correct syntax. The error message I receive is Error in file(file, "r") : cannot open file [file name] I have the data in text files in white-space delimited form. I put them

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... Thanks in advance Laurent ps : sorry for my english Laurent William Dubroca Centre de

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,

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? Thanks, Felix -- Felix Tiefenbacher Eidg. Institut f?r Schnee- und

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

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.

Can anyone tell me what's wrong with this command?? xx<-subset(x,LOCAL.NAME==c("Chifumbata","Chikota"),select=c(13,16,19,23,26,2 9,30,33:48)) Warning message: longer object length is not a multiple of shorter object length in: LOCAL.NAME == c("Chifumbata", "Chikota") both of the following commands work fine

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")

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 am quite new to R, so please bear over with me if I have problems with the R terminology. I want to (try to) use R for some analyses within vegetation ecology, using the vegan package. 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 %. I

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'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. This is the

Dear All, I am new to R and can see it is a very powerful and versatile system for programming and statistical analysis. Say I have written a simple function and want to use it on a regular basis. I have the file as a text file say 'c:\R-funcs\func.txt' how do I get R to find it on the hard disc or alternatively where is the default location for looking up functions where I can place

Hi all, there is a vector v with several NAs. I want to create a new vector n of the same length as v and the same NAs as in v and tried this: n <- vector(length=length(v), mode="numeric") replace(n, which(is.na(v)), NA) but this does't work, all values in n are 0.
