It is known (several discussions on internet) that axis() cannot be used after fields:::image.plot() (axis() shows nothing). However, if points(1.5, 1.5, type="p") is inserted before the axis() finctions, it works. I have investigated what points(1.5, 1.5, type="p") is doing to allow axis to work and I don't find a solution. par() options are identical (p1 and p2 are identical). Has someone a solution ? Thanks Marc library(fields) p0 <- par(no.readonly=TRUE) image.plot(D, co...

Dear All, I am using the scatter.dudi finction in the 'ade4' package to produce correspondence analysis (nice) plots. I do not seem to figure out how to plot the raw coordinates only -- or column coordinates only. I would appreciate any help in doing that. Here is the example I am following -- from the package. data(banque) > banque.acm <- dudi.acm(banque, scann = FALSE, nf =

I used the AR modelling written for R (S) on blood pressure and heart rate signals. I used 60 one second samples and a model order of 20. I used the "ar" finction in the "ts" package. Given that blood pressure is measured in mmHg would the spectral density (on the graph displayed be [mmHg]sq/Hz ? And the heart rate is measured in Beats Per Minute (bpm) - so would the

Hi all: Newbies (and others!) may find useful the R Reference Card made available by Tom Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf or through the "Contributed" link on CRAN (where some other reference cards are also linked). It categorizes and organizes a bunch of R's basic, most used functions so that they can be easily found. For example, paste() is

For instance the write_callback thing: client_data ? can it be a pointer to just about anything? For instance a pointer to a two-dimensional array? Are those FLAC-WAV and WAV-FLAC examples the only examples available? What would be the best approach to read a FLAC file to an array of some kind? Passing a pointer to the array as ?client_data?? I'd like to use a two-dimensional array, but

Hi, Which user-authentication plugins should one try first? Too many out there and too little time to try them all fairly. Thanks for your recommendation. cheers! -- Posted via http://www.ruby-forum.com/.

Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the

I assume you mean: https://www.xiph.org/flac/api/group__flac__stream__decoder.html#ga13 which defines the type: typedef FLAC__StreamDecoderWriteStatus (* FLAC__StreamDecoderWriteCallback) (const FLAC__StreamDecoder *decoder,

Any ideas on this? How does one drill down into
