Dear all, I would like to announce the availability of a new package on CRAN: RNetCDF: R Interface to NetCDF Datasets This package provides an interface to Unidata's NetCDF library functions (version 3) and furthermore access to Unidata's udunits calendar conversions. The routines and the documentation follow the NetCDF and udunits C interface, so the corresponding manuals can be

Dear list users How is it possible to visualise both a linear trend line and a quadratic trend line on a plot of two variables? Here my almost working exsample. data(Duncan) attach(Duncan) plot(prestige ~ income) abline(lm(prestige ~ income), col=2, lwd=2) Now I would like to add yet another trend line, but this time a quadratic one. So I have two trend lines. One linear trend line

Hi all -- I'm trying to use R for my "Analysis of Categorical Data" class, but I can't figure out how to do a weighted linear trend analysis. I have a table of categorical data, to which I've assigned weights to the rows and columns. I need to calculate r and M^2, which is apparently done in SAS using "PROC FREQ" and in STATA using "correlate var1 var2

I'm fitting a mixed effects model: fit.1 <- lme(y~x,random=~1|id,data=df) There are two different observations for each id for both x and y. When I use plot(fit.1), there is a strong increasing linear trend in the residuals versus the fitted values (with no outliers). This also happens if I use random=~x|id. Am I specifying something incorrectly? Rick B.

Hi Im confused by one thing, and if someone can explain it I would be a happy > rev(strsplit("hej",NULL)) [[1]] [1] "h" "e" "j" > lapply(strsplit("hej",NULL),rev) [[1]] [1] "j" "e" "h" Why dossent the first one work? What is it in R that "fails" so to say that you need to use lapply for it to get

Dear people, I've a problem in doing a power calculation. In Fryer and Nicholson (1993), ICES J. mar. Sci. 50: 161-168 page 164 an example is given with the following characteristics T=5, points in time R=5, replicates Var.within=0.1 q=10, a 10% increase per year The degrees of freedom for the test are calculated as Vl=T*R-2=23 and the non-centrality parameter Dl=4.54. Using this they get a

Dear R-users I would like to draw a barplot with a special y-axis. Most of my data points are in the range from -50 to 50, apart from one value that is 550. I would now like to have a y-axis from -50 to 50, then a "break" and the "rest" of the y-axis, let's say from 500 to 600. In order to make clear what I'm trying to do, I attached a figure. Is it possible to do

hi, i've been trying around for a month or so to get isolinux on my toshiba satellite 4010cdt running. It doesn't really work.

Hi I am struggling to fit a non-linear trend using the likfit function in geoR. Specifically I want a sigmoidal function, something like SSfpl in the nls package to fit the trend. But it seems trend.spatial in geoR only works with lm or glm type models. Any ideas how I can specify the model to calculate the kriging parameters using REML, including the parameters of a sigmoidal trend function
