[R] Gelman-Rubin convergence diagnostics via coda package

Dear, I'm trying to run diagnostics on MCMC analysis (fitting a log-linear model to rates data). I'm getting an error message when trying Gelman-Rubin shrink factor plot: >gelman.plot(out) Error in chol.default(W) : the leading minor of order 2 is not positive definite I take it that somewher

[R] Generating time progressing line for Google Earth

Dear, I am trying to visualise a time-progressing line (it's supposed to represent spread patterns) using brew package and Google Earth. The idea is to have a function which takes start and end point geographic coordinates, as well as number of intervals to chop the path up, and returns the coll

[R] Generating kml lines output

Dear, I would like to generate kml file with lines () of different style (definitely color, but width would also be nice to see). However with kmlLine from maptools package I am able only to output the single first Lines object (first row of SpatialLinesDataFrame) I guess the option would be to

[R] Reading parts of data files

Dear, I'm doing analysis where I need to work on relatively large (50-60 MB) text files, though I'm really interested only in parts with binary variables (named indicators1, indicators2, ... etc.) Every text file contains other numeric columns, but not always the same and not always in the same o
