I would like to use the output from the map function in the package maps for use in, say, the spatstat package. I don't quite understand the coordinates for the border of the state: Example: library(maps) iowa<-map("region","iowa) x<-iowa$x y<-iowa$y There are NA's and duplicated coordinates. What would I need to do to use this in the spatstat owin command?

Hi, I was wondering if anyone could tell me why prcomp() will "Invent" modes of variation in a PCA on identical replicates of data? I would have expected 50 (or whatever number) of identical replicates to return a null score in such an analysis (or at the least, all variables would share the same PC score). This is not the case and I was wondering could someone point me in the direction

I was hoping someone could help me! How do you exclude outliers from a set of data? Thanks, Laura [[alternative HTML version deleted]]

Dear R users, I've used the function qr.fit.sfn to estimate a quantile regression on a panel data set. Now I would like to compute an statistic to measure the goodness of fit of this model. Does someone know how could I do that? I could compute a pseudo R2 but in order to do that I would need the value of the objetive function at the optimum and I don't see how to get this from the

Hello all! As beginner I'm struggling for a while with time zones issue and can't find a suitable solution. I would be grateful for any help. Dataset imported from excel has a variable transplant.date which has been recorded with CET time zone. > subDataset$transplant.date [1] "2000-01-01 CET" "2000-01-01 CET" "2000-01-02 CET" "2000-01-02 CET"

Hi, I was wondering if anyone knows of a way by which one can estimate values from a contour plot created by using the loess function? I am hoping to use the loess contour plot as a means of interpolation to identify the loess created values at points at pre-defined (x,y) locations. Could anyone point me in the right direction please? Thanks. Laura Quinn Institute of Atmospheric Science School

Hello, I am very new to R and data analysis in general. I am trying to generate values to append to my data frame using conditional statements. I am playing with this simple example: a <- c(1:4) b <- c("meep", "foo", "meep", "foo") d <- cbind(a, b) now what I want to do is , each time there is a "meep" in column 2 of d, print

by modify I mean add, change and/or remove DNS records (depending on the values passed to the API). Also, yes I mispoke, we would only be modifying the records on one DC, and replication would take care of the rest.

I am dealing with a huge matrix in R (20 columns, 54000 rows) and have lots of missing values within the dataset which are currently displayed as the value "-999.00" I am trying to create a new matrix (or change the existing one) to display these values as "NA" so that I can then perform the necessary analysis on the columns within the matrix. The matrix name is temp and the

Hi all- I fit a zero-inflated Poisson model to model bycatch rates using an offset term for effort. I need to apply the fitted model to a datasets of varying levels of effort to predict the associated levels of bycatch. I am seeking assistance as to the correct way to code this. Thanks in advance!

Hello, I'm a beginner with R and it's the first time I'm using the R-help list... I hope I'm in the right place, if not: Sorry!! I need to do non linear regressions on a data set which columns are: "river.name" "Portata" "PTG.P" "PO4.P" "NT.N" "NH4.N" "NO3.N" "BOD5" "SiO2"

Dear Laura, It looks like you want to remove all rows for which each column is NA. You can to that with the code below. na.matrix <- is.na(MyData) all.na.row <- apply(na.matrix, 1, all) MyData[!all.na.row, ] Best regards, ir.

Hi, I'm having a mental block as to how I can automatically assign filenames to the output of the following code. I am wishing to create a separate .png file for every image created, each of them having a sequential filename ie "sourcefile_index.png" so that I can create a movie from them. Please could someone tell me where I am going wrong? the following code works fine and

Hi, Just a quick query - if I'm creating a function to produce a number of histograms per page of output (one per column from a matrix), how can I pass the column name of the matrix into the title (or indeed to form part of the x-axis label)?

Hi, Is it possible to recreate "smoothed" data sets in R, by performing a PCA and then reconstructing a data set from say the first 2/3 EOFs? I've had a look in the help pages and don't seem to find anything relevant.

Dear R users, I am in trouble using the function solve(matrix) in a loop. When it happens that I have a singular matrix, I get an error message saying so and the loop stops. My question is if there in any way to keep on going in the loop. Thank you in advance, Laura *---------------------------------------------------------* Laura Antolini, PhD Department of

Daniel, I could kiss you :D I am using the default SSL certs in samba. I tried connecting to the new DC using it's FQDN instead of it's IP, and BAM, it connected just fine.
