Hello Dimitris, I was goggling for some help on Sensitivity vs 1-specificity and saw your link. I hope you can be of help to me in one of the issue that I am facing in generating combo chart(bar chart and plot). I am a novice and have some difficulty in getting this logic correct. I am give a dataset (I am attaching a sample dataset). I am using a barplot() and passing values for

Hi, I'm having trouble installing R. I'm sure this is a very simple problem but I'm stuck. When running the ./configure script, to install R (version 1.6) on Solaris 2.6, I get an error message at the end of the configuration process "WARNING: f77 and cc disagree on int and double. configure: error: maybe change CFLAGS or FFLAGS?" However, I have seen no documentation on

Dear R-helper, I wonder if anyone can help me. I am trying to convert a dataset to a format recognizable by a software onboard a research vessel but I am having problems with some steps. I have a data frame as follows: Conc Lat Lon Depth Point0000 56.25 -5.65 70 Point0001 56.55 -5.35 85 Point0002 56.25 -5.65 65 Point0003 56.37

Hi, Does anyone know how to compute the confidence prediction intervals for a nonlinear least squares models (nls)? I was trying to use the function 'predict' as I usually do for other models fitting (glm, lm, gams...), but it seems that se.fit, and interval computation is not implemented for the nls...

Hi, I am hoping someone can help me with a sampling question. I am using the following function to sample 10 unique observations: x <- sample(1:100, 10, replace=F) Given the first 10 observations, I need to sample another 5 unique observations from the remainder. I essentially want to do a Monte Carlo type analysis on the results. I would appreciate any feedback. Thanks -- View this

Hi, I've got the R library "mgcv" for GAM written by Simon Wood which works well in many instances. However, over the years I got attached to the S+ implementation of GAM which allows loess smoothing in more than 1 dimension as well as spline smoothing. Has anyone ported the S+ GAM library to R?

Hi, I want to do a barplot with no black lines drawn around each bar and no space between each bar. I can do the nospace bit but keep getting black line around each bar no matter what I try. Ie. for a red bar I want a red border, for a yellow bar a yellow border and so on. I've tried everything I can think of but no luck. Any suggestions? At the moment I'm using R 5.1 under Redhat Linux

Dear all, I am developing Fortran code for general distribution, which will assist fisheries scientists in making forecasts about future fish-stock population dynamics. I have produced an S-PLUS script which takes the output from this code and generates the necessary summary plots, but I am aware that not everyone can afford to buy S-PLUS. Hence, I am interested in the use of R to produce these

Hi I am having difficulty getting the right format for a lattice plot I am trying to produce. Here is a pic of the plot as I get it now http://i235.photobucket.com/albums/ee37/scotrivers/lattice_plot01.jpg and here is the code I am using: RN<-read.csv("N:/data.dat",header=T) DATA<-RN[is.element(RN$age,0:3),] #select data on age

Hi, I have matrix of sea bottom depths that I am plotting in R with the function 'image'. I am particularly interested in the 200m depth contour (I'm using 'distance from this feature' as a covariate in a model) and would like to extract the data at evenly spaced points along it. I can easily superimpose a line at 200m using the function 'contour'. What I want to
