...; tkfilefind("C:/") [1] "C:/Program/Files" "/R/rw1031/FAQ" I was wondering if there was an easier way around these problems? I find the tkfilefind function very useful when writing small GUI's that read/write data from files. Cheers, Jonathan -- Jonathan L.

Dear List, I am looking for a possibility to fit a mixture model under R using maximum likelihood estimation. Venables and Ripley describe a solution working under S+ (in MASS, 3. ed., p. 263) which requires the D system function and deriv3. This solution does not seem to be portable to R or at least I do not realise how. Is there anyone who a) knows how one could make the MASS-method run under

...ed images together with conversions between all three formats. The classes allow images also to have a coordinate system attached, such that, e.g., locator() can be used meaningfully on geographical maps. This is a first release, all comments and feedback are more than welcome (thanks to Jonathan Marchini for valuable feedback on the first development version).

Dear Fred, If x1 and x2 are *not* normally distributed, you can use independent component analysis (ICA) which is based on the idea that x will be "more normal" than either x1 and x2 following the central limit theorem. See package(fastICA) by JL Marchini, C Heaton, and BD Ripley for details.

Hi, Is there any package in R which i can use for Coalescent Theory/Genelogical Trees? Is this possible to use R function in C language? I would be very thankful to you.

In the following, 'probability=T' is ignored, i.e. the vertical axis is labelled in frequencies. However hist(islands, freq=F) achieves the desired effect. > data(islands) > hist(islands, probability=T) # Vertical axis gives frequencies > hist(islands, freq=F) # Expected result --please do not edit the information below-- Version: platform = i386-pc-mingw32
