similar to: Reading Wyoming radiosonde data files with RadioSonde package

Hello, I am building a package to read in a pretty common atmospheric data format and create a SKEW-T, log p diagram (also very common for the atmospheric community). The problem is this: How should one address the (ASCII) data files so that the examples find them? I have read through the "Writing R Extensions" document and still have a problem. There seems to be some sort of

Hi All Please see the Rprofile file which i have modified as follows and after that when I start R then I see that R says to me "TRUE" for all the packages implying that all loaded at once. But when i try to use commands as simple as help("lm"), it doesnt work nor any of the menu "Packages" is not working. Although the regression using lm ( Y ~ X ) is working

Sir, I want to solve the equation Q(u)=mean, where Q(u) represents the quantile function. Here my Q(u)=(c*u^lamda1)/((1-u)^lamda2), which is the quantile function of Davies (Power-pareto) distribution. Hence I want to solve , *(c*u^lamda1)/((1-u)^lamda2)=28353.7....(Eq.1)* where lamda1=0.03399381, lamda2=0.1074444 and c=26104.50. When I used the package 'Davies' and solved Eq 1, I got the

Hi, I have been trying to make a surface plot using R - I came across functions like plot.surface, surface but I could not use these functions as they seem to be in FOO package which I cannot load. I also want to make a plane that fits the surface plot. Can anyone help? divya [[alternative HTML version deleted]]

Hi all, Appologies for the rather basic IO question but I am rather new to R... Migrated from IDL/Matlab recently. I have a rather simple Fortran control file (sigh...) that I am trying to parse and read using R. My problem is that the file's format is somewhat flexible. Imagine: --- 1> 39 1901 2> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 3> 22 24 26 28 30 32 34 36

Would anyone help me solve my problem with R, please? I am very new to R. I am doing logistic regression analysis on the presence/absence of salamanders using several predictor variables, as shown below. I have checked my data, but I didn't find any 'NA' or empty cells. When I used step() or stepAIC to select significant predictor variables, <none>s appear to places where

Dear R-list members, Some months ago I wrote a message on the usage of gnls (nlme library) and here I come again. Let me give an example: I have a 10 year length-at-age data set of 10 fishes (see growth.dat at the end of this message) and I want to fit a von Bertalanffy growth model, Li= Linf*(1-exp(-k*(ti-t0))) where Li = length at age i, Linf= asymptotic length, k= curvature parameter, ti=

I have a FreeBSD 4.8-Release machine that I upgraded from a 4.5 or 4.4 machine. It works just great for about 9 days, then processes will not die. It starts to become a problem when I can't kill processes, restart services, connections hang, and I can't reboot or shutdown, I have to do a hard reset. I can't really find anything in the logs to indicate what is giving me

Hi, I have a question about estimating IRT models by using nlme, not just rasch model, but also other models.
