Dear members, How can I read and plot an ArcGIS raster file into R ? The file has extension .aux and contains floating point bathymetry data. The purpose is to create a spatial model in R that uses ArcGIS map data. I have managed to read and plot various shape files into my R project, but I am stuck with this now. I am new to this list and also to R, so any help would be much appreciated. Many

Dear all, I would like to know whether it is possible to unlist elements and keep the original format of the data. To make it more clear, let me give an exemple: I have a list l of dataframes that I created with apply but which looks like this: x1=data.frame(Name=LETTERS[1:2],Age=1:2) x2=data.frame(Name=LETTERS[3:4],Age=3:4) l=list(x1,x2) l [[1]] Name Age 1 A 1 2 B 2 [[2]] Name

Dear all, I would like to know if there is an easy to transform a vector of strings to a vector of integers.

Dear all, I have a problem with constructing a nested loop. I have two matrices: pnr: 800 rows 14 columns where rows are 40x20 meaning that 40 rows belong to one of twenty objects in the matrix pnr mvp: 20 rows and 14 columns I want to: calculate a distance value with the first 40 rows of pnr but 20times with the 1st row of mvp then the next 40 rows of pnr and 20times with the second row

Hi, I am facing a problem with the legend, I don?t know how to use the fill option in the legend in order to achieve the same standard gray levels that are plotted. Sorry for this easy one, but I really did not find anything so far. It works fine with color: ###### C O L O R mat <- matrix(2,3,rep(2,6)) rownames(mat)<-c("A","B","C") par(xpd=T,

HI! I?ve 3 vectors of different length (a,b,c) and want to arrange them in a matrix a,b,c as rows and the figures of these vectors in the columns (with that matrix i want to calculate a distance between thes vectors - vegan - vegdist - horn). Is there a possibilty to create such a matrix and to fill up the missing fields with NA?s automatically???? Thanx marten winter -- *Marten Winter*

Dear friends: I am a new R user, and not very good at statistics and maths I find it difficult to find the minimum of this item: ((p*(b-1)-1)*(p+1)^(b-1)+1)/p^2 It seems that the method optim can find the minimum. I tried several times , but R constanly tells that " failure to find b or p" Would you please give some suggestions? Thanks in advance. Best

Dear all: "predict.glm" provides an example to perform logistic regression when the response variable is a tow-columned matrix.

Which is the most transparent way to handle character encodings in your experience? For a small internal application in Spanish I was going to go with everything in UTF-8, database and views. Does that work smooth in your experience? How do you handle the encoding of input coming from forms? -- fxn

Hi, We are running a samba server ( Version 3.0.10-1.4E.6.2 ) on a redHat RHEL release 4 (Nahant Update 3).

I have a data set with 35 observations and 4 variables. I have removed 4 observations as they were skewing the data analysis but I want to dummy them back in, (not entirely sure on the reason, but have been told I should try). I have used this in order to do it, but I am not getting any statistical analysis with my dummy it's all NA. > dummy15=rep(0, times=n) > dummy15[15]=1 >

Greetings, Yet another strange pattern of traffic is being halted at the shorewall firewall, but I have no idea what this is.

Dear friends : using the "glm" function and setting family=binomial, I got a list of coefficients. The coefficients reflect the effects of predicted variables on the probability of the response to be "1". My response variable consists of "A" and "D" . I don't know which level of the response was set to be 1. is the first element of the response set
